I got my valentini yesterday morning and I just noticed a very small pink bump - the reason even saw it was that it looked as if my clown fish gave him a kiss. It was as if the puffer let him do it.
Is it anything to be worried about?
Where is the bump located on the fish. If you just got it it could have been nipped by another fish at the lfs. Does it look irritated or is it just a bump?
