The fish is very active and adds a lot of visual interest to the tank. It swims gracefully and doesn’t seem stressed. I’ve kept it with a few peaceful community fish and it coexists well. The color and shape are impressive and it’s a real highlight in the aquarium.

It’s a beautiful fish with a unique appearance. It stays near the bottom and moves smoothly. I noticed it hides when the tank is disturbed, but otherwise it’s calm and healthy. Good for larger tanks with stable water conditions.
