I just bought two small perc clowns
and today i noticed that one of them has this string like thing hanging from under his belly in between his two bottom fins.
I hope it is nothing serious.
and i tryed to feed them a few flekes but they dont seem to be very hungry.
and the smaller one likes to hide behind a decoration even though there are no other fish in the aquarium exept the other small clown and a cleaner shrimp.
I would apprieciate any advice,Thanks
