Fish Fanatic
after a week or so of a male chasing this one female around, she now has this white blotch on her tailfin, none ofthe other fish have it, and its only one blotch on her tailfin, Is she sick..or pregant.. or what is it?
not a sign of pregnancy
does it look like a grain of salt?
does it look fluffy?
If i was you i would treat it with a anti fungus and finrot med asap.

Hya you could do to check your water quality and do some tests ammonia and nitrite or go take a sample to your local aquarium shop they will do it for you. just thought id put a suggestion in but it sounds as though u platy has fungus.and turn the airation up in your tank with meds![]()
