Funny you mentioned that, my girlfriend has one purple firefish, and when there is movement, boom! it darts into a hole. I think the problem is that it's a loner firefish, and I've read they do better in pairs.Chubosco said:I have the "regular" firefish not the more expensive purple firefish. He eats frozen shrimp and formula one. Bad thing about this firefish, after he became comfortable with the tank, he now dives for cover at any sudden movement. He comes back out after 30-60 seconds but he has taught the other fish to be scared of my apporach. I am getting rid of him as soon as I can catch him. He is just too nervous and freaking out everything else in the tank. Oh yeah, I paid 16.99 for him in Columbus, Ohio.
