🎃 What’s Halloween without a few sharp teeth? 🐟
Red-bellied piranhas may have a fearsome reputation, but there’s more to these fish than meets the eye!
Native to South America, these freshwater fish have razor-sharp, interlocking teeth that help them tear through food. ...But despite what Hollywood might have you believe, they’re not constantly on the hunt! They’re also important scavengers, feeding on fish, insects, crustaceans and even the occasional fruit. And those large schools they swim in? They’re often more about protection from predators than hunting prey!
Want to meet these toothy residents for yourself? Join us for Pumpkins & Piranhas, October 22–25 and 30, featuring underwater jack-o’-lanterns, costumed divers, animal encounters and plenty of spooky fun!

You better not mess with our gang 😤
Everything you’re about to learn is completely useless because none of it is true.
🐟 FUN FACT: Discus fish are devoted parents!
Unlike most fish, both mom and dad help care for their young. Even cooler? Newly hatched discus feed on a nutrient-rich mucus produced by their parents’ skin — basically the fish version of baby food!
Talk about a family meal. ...💙
We didn’t realize we had so many celebrities swimming around here.
