I've had a CBB for about 9 months. She ate all my feather dusters and also my hawaiian one. She was really small when I got her and now she's about 3" long.
She doesn't touch any of my corals and eats all the frozen foods I give my fish. I just think you have to feed them 2 or 3 times a day.
I had to take my green open brain out because she started picking on it a bit. I think she was just looking for pods etc and didn't mean to hurt the coral. Every time I put my hand in the tank to clean, she swims between my fingers and eats pods that come out of the rocks when I clean.
