I've had a love/hate relationship with this fish. He's cool and I've learned to live with his constant rearrangement. He's actively hunting frozen foods that I feed the tank and is sifting like a mad man as well. But, he has an attitude problem!
Tonight when feeding a couple nassarius snails were surfing around near him and he just went and nipped all of their eye stalks! I believe he's killed one, and ironically now I think he's trying to bury it.
After the snail incident he's been swimming over to my clownfish and opening his mouth widely at them, as if he's sizing them up - "which one of you will fit in my mouth?"
Should I be concerned?
