I have two clown fish in a 32 gallon bio cube and my female clown fish bites small chunks of skin off my hand every time I stick it in the tank. Sometimes it even nearly jumps out of the water. I have began to think it is because she might have laid eggs. I am thinking this because she sort of protects a area in the tank when I put my hand in. Does any body know why and how I can stop it from biting me?
