My cat sits on the floor in front of the tank watching the fish, then jumps at the glass to pounce at the fish, scaring my poor firefish out of its wits and sends it darting into its cave. This goes on all day long. Now my firefish has developed a white spot on its tail, maybe the first sign of itch? Violet (the firefish) is eating and doing okay otherwise, I'm sure she is just totally stressed from seeing what must look like a giant predator flying at her all the time. Has anyone else run into this problem?
