some of you may remember me saying that i got a gold nugget with a sunken belly and then he recovered - well now he is gradually swimming round the tank more and more. but i caught my angels trying to nip his fins - in fact whenever he moves, all they do is swim after him - all six of them! and try and bite his fins! what should I do? he is very small, no more than 3 centimetres long. i feel sorry for him because he is trying to swim around but they dont let him. i have a 10 gallon hospital tank, should i move him to this? i was thinking maybe this could stress him out? he is in a big tank, and lots of hiding places, but its only when he comes out that they try and bite him.
