The white tip shark looks stunning in my 55-gallon tank. I added a bit of salt as recommended and it’s been thriving for three months. It’s peaceful and schools well with other catfish. Only issue is it does eat small fry, so I’ve removed some tiny fish from the tank.

I was skeptical at first because of the name, but it’s actually a beautiful catfish. It’s not aggressive and fits well in a community tank. I keep it in brackish water and it’s active and healthy.

Great addition to my aquarium. The fish is sleek and looks like a real shark. I followed the care guide and added salt as suggested. It’s calm and has been eating well since arrival.
