my brother took in some kribs in his goldfish tank, no idea why, and they have eaten off the fins of one of the fish, so last night I moved her into my tank last night with "peaceful" fish. Well when I woke up she was missing an eye. IU think my port acara who is usually peaceful must have eaten it. I am very nervous about her. I dont want her to die, as I like her alot. I took out the kribs, and moved her back into their own tank,
