I was initially worried about the size, but the fish grows slowly and doesn’t stress the tank. It’s peaceful and only active at night. I keep it with some peaceful community fish, and there’s no aggression.

This fish is a real showpiece. The way it glides through the water is mesmerizing. I’ve read about its sensitivity to lighting, and I’ve kept the tank dim, which works perfectly. It’s easy to care for once the setup is complete.
