Velvet Nudibranch
 

Just got one from aquarium illusions. Was eating fine, but it tends to like to ball up and float around...it's as if he's too weak to hang on to the glass. My current is not overly strong...in fact it's kinda weak. Is this normal?

Do you have enough flatworms to keep it eating well? I believe that is all velvets eat. (could be mistaken)

thy only eat flat worms,no worms they die

there only goal in life is to eat bristol worms. Once your tank is worm free they die..Aquarium illusions should have told you that and if they didnt take it back for a refund or credit
