No, the original fault is yours, CAEs become protein eaters as they mature. They shouild have been removed long ago before the situation arose. You brought the fish home, it is your responsibilty and the balme is yours, not the fish which were only doing what they do in the wild. If you do not know what to do, ask. If you don't care about torturing a fish for being true to its nature, you do not belong in the hobby or on this forum. Taking out your anger and frustration on a fish is a highly intelligent thing to do.
