Hello all, So tonight while i was feeding i found that one of my platies has a white growth on it at the base of its tail. Now it seems to go to the otherside but is not white but is discolored. She has also been hiding a lot, and not eating a whole but is coming out to eat. Now i think that this is a infection of some kind. How can i treat her? Tank info: 29gal 78°f Ph 7.6 A 0 No2 0 No3 20 (friday before water change ~25%) Stock: 8 black skirt tetras 4 Platies 5 Ghost shrimp I currently dont have an open tank to put her in at this time since i just got a new betta that took over my 10gal that was empty. Any advice would be great.
