On both of the fish 1 of the first front fins have gone.I dont know what they're called but they are the ones they use to move with.I cant see any marks or anything where it looks like there is any disease.The goldfish looks like his is growing back.I did'nt know they were like this when i bought them but if they die im going to complain to them.The tank they were in looked clean and the rest of the fish looked healthy,My fish do apart from missing fins.I was wondering that being really tiny because they are only about 2cm big i was wondering if they were just growing there fins? or does that make me sound silly.lol.
