Babies with Bite – Piranha Hatchlings Are a First at the Tennessee Aquarium

Earlier this year, Aquarist Brad Thompson made a unique discovery. While checking the Red Piranha pop-up tank in the Aquarium’s Ranger Rick gallery, he noticed some tiny, wiggly specks gathered around the water’s surface.

“It was very surprising to find baby piranhas in the tank,” Thompson said. “But I was able to quickly gather them up and place them in a separate tank behind the scenes to keep them safe. This is the first time we have raised piranhas at the Aquarium.” A special nursery for the babies was set up within a smaller container, called a pal pen. This tank floated inside a larger system which provided the babies with clean water.

At their tiniest stage, the baby Piranhas began a diet of Mysid Shrimp and were later introduced to bloodworms and shrimp as they grew.


They developed quickly and soon took on more of a recognizable piranha-like shape.


Later came the coloring similar to the adults.


In May, the young piranhas were sent to Wonders of Wildlife in Springfield, MO. We are happy to share our success with other institutions.

Tennessee Aquarium Announces First Penguin Chick of 2014

The Tennessee Aquarium's first penguin chick of 2014 at two days old

There’s a fluffy new face in the Tennessee Aquarium’s Penguins’ Rock exhibit. Aviculturists welcomed the new chick to the colony in June. The proud parents, “Chaos” and “Merlin,” stay busy snuggling their baby in the nest and seem to enjoy showing it off to everyone.

“Both parents have very laid back personalities, which is helpful when we need to do weight checks and clean the nest,” said senior aviculturist Amy Graves. “They’re also a great parental team. Merlin serves as protector and Chaos does a great job feeding.”

Chaos certainly keeps busy since this tiny bird has a giant appetite. Aquarium guests can have fun eavesdropping on this family. A microphone inside the exhibit picks up the chick’s vocalizations whenever it begs to be fed, which seems to be almost constantly lately. The sounds of the colony are audible throughout Penguins’ Rock. But, mom responds to the begging and appears to be keeping pace. Her baby consistently weighs in at the high end of the healthy range during veterinary exams. “Baby penguins should experience rapid growth,” said Graves. “We track each chick’s progress through frequent weigh-ins and compare the results to the ranges we know are considered healthy. Since this penguin is staying pretty pudgy, it’s clear that the parents are doing a great job with feeding.”

Macaroni chick at 16 days old

The Aquarium’s penguin experts hope this “big mac” sets a good example for the chicks that follow it. Both in demeanor and rapid growth.

Last year aviculturists had their hands full supplementing feedings for a couple of chicks up to five times each day when sluggish weight gains indicated the parents were not delivering enough nutrition on their own.

Aviculturist Loribeth Aldrich says even though the chick is very vocal, it seems to have inherited its parent’s demeanor. “He’s pretty laid-back and easygoing,” said Aldrich. “The chick doesn’t mind being handled during exams or being photographed.”

This is quite a switch from “Pepper,” another Macaroni who was also the Aquarium’s very first baby penguin hatchling in 2009. “She was a feisty bird almost from the day she hatched,” said Aldrich.

Earlier this year, Pepper and ten other penguins that were reared at the Aquarium were moved to other institutions accredited by the Association of Zoos and Aquariums. They will have the opportunity to have offspring of their own while bolstering the overall genetic diversity of the Macaroni and Gentoo population in human care. This transfer also affords the Aquarium’s colony more flipper room during the breeding season.

This new Macaroni penguin is the first for the 2014 season and it’s possible that aviculturists will remain very busy this season with additional chicks.

Visitors can see the new chick inside an acrylic “playpen” on the right-hand side of the exhibit. It will remain inside this protective barrier for several more weeks before it will be allowed to roam outside the nest. “Penguins need their waterproof swim feathers before they are ready to go out on their own,” said Graves. “Right now, the chick is still dependent on mom and dad, but they seem to like that just fine.”

The chick’s gender will be determined during a blood test later this year. At that time, a Facebook contest is planned to find the perfect name for him or her.

Guests who may want a “bird’s eye” view during nesting season, can choose to add the Ocean Journey Backstage Pass to their regular Aquarium admission. This behind-the-scenes experience allows guests into one of the “Keepers Only” areas to see the nesting penguins, eggs and at least one plump little penguin.

Security Camera Catches Penguin Thief

Nipper, a male Gentoo penguin, is noted by Aquarium experts as Penguins' Rock's most enthusiastic nest builder. Sometimes, even before the nesting rocks are placed on exhibit each nesting season, he will begin "building" with ice cubes from feeding buckets.

So Nipper wasted no time getting to work when this year's rocks were delivered by our penguin caretakers. While his neighbor Hercules (a male Gentoo) was distracted by interactions with Shamrock (a female Gentoo), Nipper was nabbing nesting rocks as his mate Flower watched his back.


Egg update: Since this was filmed, Nipper and Flower have laid an egg. The current total egg count stands at 6.* With more potential penguin parents still pairing up and building nests, the season is still off to great start!


*Keep in mind, each penguin egg has a long journey ahead of it. Lots of factors can impact the chances of hatching and newborn chicks face even more challenges. Again, keep your flippers crossed for a new group of healthy chicks later this summer!

Party on the River: Frequently Asked Questions During the Riverbend Festival

Photo via Chattanooga CVB

Is the Aquarium open during Riverbend? 

Yes! The Aquarium is open 363 days a year* with regular hours – 10 am to 7:30 pm. The last admittance to the Aquarium’s buildings is at 6 pm each day. There is no change in hours of operation during the Riverbend Festival. (*The Aquarium IS closed on Thanksgiving Day and Christmas Day each year.)

Where can I park to visit the Aquarium?

The Aquarium’s parking lot is open and can be accessed by turning left on Aquarium Way from Broad Street. (Then turn right into our gated lot, which is halfway between Broad Street and Chestnut Street.)

Do I need a Riverbend wristband to enter the Aquarium?

No. Only Aquarium tickets are needed to enter the Aquarium during Riverbend. You can get yours online, at the Aquarium’s ticketing center or the IMAX 3D Theater. Tickets are good for entry into both Aquarium buildings.

Is the Aquarium crowded during the week of Riverbend?

The week of Riverbend is a great time to visit the Aquarium. We do not typically experience a high volume of visitors during the morning and early afternoon. Since the festival gates don’t open until 5 pm each day, the earlier you arrive, the more time you will have to explore before festival-goers start arriving downtown.

Is there anything special happening at the Aquarium during Riverbend?

Yes. As part of the Bend Unplugged series, Playing on the Planet will perform between the Aquarium buildings on Saturday, June 7 from 2:30 to 3:30 pm. They will perform that night at Riverbend starting at 5:45 pm.

What if I am coming to Chattanooga to visit the Aquarium but am interested in checking out the Riverbend Festival while I’m there?

One-night wristbands are available at the Riverbend entry gates for $26. If you are in town for more than one night, weekly admission is also available. You can get more information on the festival website.

Nesting Season Going Swimmingly on Penguins’ Rock


Seven otters are making a big splash in the Aquarium’s new River Otters Falls exhibit, located atop the River Journey building. Meanwhile there’s plenty of excitement in Ocean Journey as well. Five pairs of penguins spent the month of May building nests and laying eggs. Our aviculturists are currently monitoring the progress of six eggs. Right now, the count is split down the middle with three eggs from each species.

Macaroni penguins typically lay two eggs, but the first one is almost always smaller and quickly discarded by the parents. One scientific explanation for this behavior is that the first egg may serve to distract predators, giving the second egg a better chance at survival.

In contrast, Gentoo penguins may lay up to two viable eggs each year. With a couple of Gentoo pairs still building nests, there’s a chance for more eggs this season.

As much fun as egg watching is this time of year, we are always careful to remember that, “You never count your penguins before they hatch.” Inexperienced parents can be rough on eggs (and chicks) and sometimes they get damaged or neglected for unknown reasons. Our experts want the birds to develop their parental skills. Therefore, aviculturists carefully monitor each pair and their eggs. If all goes well, there may be some baby penguins to enjoy watching.

In the meantime, we look forward to keeping you updated throughout the season. You can also watch the penguins’ activity in real time with our Penguin Rock Cam.

Keep your flippers crossed for new chicks this summer!

The Top 5 Reasons to Kick Off Summer in Downtown Chattanooga

Memorial Day weekend traditionally kicks off the summer travel season. Here are five reasons to make Downtown Chattanooga a part of your summer plans. With new attractions, great dining options and more to explore, there’s something for everyone in downtown.

1) All New River Otter Falls


North American River Otters are furry, feisty and fun to watch. Even though these charismatic creatures are a native Southeastern species, they aren't easy to spot in the wild. But otter fans can come face-to- furry-face with their favorite mammals at River Otter Falls inside the Tennessee Aquarium’s Cove Forest. 

A romp of agile otters have a spacious new home to enjoy. It’s designed to bring out the best in their natural behaviors. You’ll see them scampering up and down multi-tiered landscape which features a lengthy stream, waterfalls and cascades. You’ll be fascinated by their climbing abilities and athleticism underwater.

The otters will explore their habitat in various groups each day, so you might see two, three or four otters at any one time playfully tussling with one another.

2) Galapagos 3D: Nature’s Wonderland – Narrated by Jeff Corwin


In the vastness of the Pacific Ocean, there is a paradise unlike any other: the Galapagos. Among these remote volcanic islands, life has played out over millions of years in relative isolation. The result is a wonderland of nature, with a remarkable collection of plants and charismatic animals that have all adapted to this unique environment. Meet giant half-ton tortoises and marine iguanas that spit sea-salt. Dance with the tropical albatrosses and hunt fishes with the colorful blue-footed boobies. Swim with tiny penguins thousands of miles away from their natural habitats. This is a story of discovery, of survival against the odds, and of nature's ingenuity, all brought to life in stunning 3D.

3) High Point Climbing and Fitness

Opened in late 2013, High Point Climbing And Fitness is a one of the nation’s most unique climbing facilities, offering climbing inside and outside. 

The outdoor climbing walls feature climbing on transparent climbing material that is like nothing else. There are lead, top rope, and auto-belay walls, as well as a 15 meter speed climbing wall. 

Inside, there are climbing areas for everyone. From beginner walls to  top roping room, leading climbing pit, and two boulder areas. There is even a campus, moon, and adjustable wall. 

4) The Wizard of Oz at the Creative Discovery Museum


We’re off to see The Wizard at the Creative Discovery Museum this summer.  The Museum hosts the first-ever licensed traveling educational exhibit based on the beloved movie classic. The Wizard of Oz exhibit is set to open on Saturday, May 24, 2014.

Visit Professor Marvel’s Wagon and create your own tornado in Dorothy’s bedroom. Explore Munchkin houses and meet Dorothy’s friends the Scarecrow, the Cowardly Lion and the Tin Man. Enter The Emerald City and create a “Horse of a Different Color,” play at the kaleidoscope and prism stations, but “pay no attention to the man behind the curtain.” Next, climb the mountain to the Wicked Witch’s Castle to capture the Wicked Witch’s broom from Winged Monkeys. Finally, click your heels three times while reciting, “There’s no place like home,” as guests depart the Land of Oz.

5) Local Markets on Saturday and Sunday 



This year marks the opening of the 5th season for the Chattanooga River Market.  Held on the beautiful riverfront downtown at the Tennessee Aquarium Plaza, this market is a weekly showcase of the talented artists and craftsmen in our area. Visitors to the Saturday Market will find handmade jewelry, locally designed and made children’s apparel, pottery, photography, woodworks, soaps, glasswork, artisan bath products and more. Check out the live music schedule here.

On Sundays, the Chattanooga Market at the First Tennessee Pavilion features farm fresh produce, meats, cheeses and artisan foods, as well as, local arts & crafts such as photography, canvas art, sculpture, jewelry, soaps and many other handmade products.  Patrons enjoy weekly themed events such as the popular Beast Feast BBQ, Chattanooga Oktoberfest and theCast Iron Cook-off.

Local food trucks and eateries offer the cultural flavors of the South on the patio every week for lunch and refreshments. 

The Chattanooga Market is held Sundays, April 27-Nov. 23, from 11am-4pm at the First Tennessee Pavilion. This year, a Wednesday market was added to the weekly schedule at the pavilion.

A Light Bulb Moment: Bright Ideas for Going Green

Recently, 42 light fixtures that previously illuminated the 618,000 gallon Secret Reef tank in Ocean Journey were replaced with 28 more energy efficient lamps. Members and frequent visitors may have noticed an improvement in visibility and color inside the exhibit.

New lighting above the Secret Reef tank

But these new fixtures did more than enhance the view – they’re helping to save a lot of energy. The previous lighting system totaled 21,600 watts while the new one provides a much better visitor experience with only 3,300 watts. Not only will the new system save energy, it will also zap an impressive $9,429 a year from the Aquarium’s energy bill – paying for itself in less than two years’ time!


This is a practical solution that you can use in your own home. Did you know that switching to more energy efficient household lighting can save up to 75% of the energy used by incandescent bulbs? Even turning off the light when you leave a room for more than 20 seconds can make a big impact.

These energy savings are great for your wallet, but even better for the wildlife in our area and all over the world. Saving energy leads to saving resources, like water and other valuable habitat space where many Aquarium animals would call home in the wild.

Want to know other ways you can join us in going green today and every day?

Conserve and Reuse Water

Whenever possible, we re-filter and reuse water in our exhibits. In Ocean Journey we reclaim 16,000 gallons of water per week! We have also installed waterless or low-flow urinals in two restrooms. 


Did you know that the River Gorge Explorer also monitors water quality along the Tennessee River? Check it out.

At home: Keep a bucket in the shower and reuse the water collected to water house plants. You can also collect larger amounts of water outside with a rain barrel. (Make your own barrel at our next rain barrel workshop.) Install low-flow showerheads, faucets, and toilets in your house to reduce the amount of water that you use in the bathroom and kitchen.


Recycle Right

We recycle paper, cardboard, glass, #1-#7 plastics, batteries, aluminum, empty aerosol cans, loose metal jar lids and steel bottle caps, electronics, wood pallets, shredded documents, toner cartridges, old carpeting, old staff uniforms, old brochures and used ticket stubs. We take metal to a salvage yard. We responsibly dispose of lamps with mercury content, light fixture ballasts, used oils, antifreeze and oil and gas filter cartridges.


A tank in the Tennessee River gallery safely showcases the effects of trash in our waterways.


At home: Find out about recycling programs in your area. Make our resources last longer by recycling everything you can: plastic, cardboard, paper, aluminum, batteries, and cell phones. Extra points for composting! Give some nutrition to your soil by composting fruit and vegetable scraps, eggshells, and coffee grounds.


Rethink Transportation

Thousands of our visitors come in groups and arrive by school bus or motor coach. In past years, hundreds of buses would idle for more than 30 minutes while waiting for passengers to re-board. Today, thanks to a partnership with the United Motor Coach Association, signage encourages drivers to limit idling to no more than five minutes, which improves air quality and helps reduce greenhouse gas emissions.


A sign outside the Aquarium asks buses and motor coaches to limit idle time.

At home: Can you bike to work? Walk to a popular lunch spot? Challenge yourself to cut your transportation costs in half by carpooling, walking, biking, and using public transportation. Talk to your co-workers and friends from school to find a way to share rides. If you can add your errands to the same trip, you’ll be extra efficient. If you’re driving, check your tire inflation. You can increase your gas mileage by up to 3 percent if you keep your tires properly inflated.
