Ok, First off, my tank is over crowded, my Fancy guppies decided to have babies... Somehow, I got a bacterial thing or some fungus gook going around in my tank. (my water is currently being treated using Pimafix and Melafix). Second, I just lost 2 fish due to some kind of growth on my mickey mouse platy it was right beneath his anal fin (I thought he just had a back up or something and was initially going to treat him for constipation, it popped up out of no where one day he had it the next he didn't and the day I saw it he died... Then my male Delta/Fancy/English Lace?!!? (I have no idea what breed) had a similar growth coming out of his left fin near his gil I'd post a pic but he's so small I don't think the camera would show it well, but I took it to PETSMART and they told me it was a fungus/ bacterial infection of sorts, since I brought along a Cherry barb (sm) female who had some type of growth coming out of her mouth didn't look the same but seemed as though it may be the start of something. I'm at a loss and i don't know what to do. They couldn't identify what it was/is but told me to treat it with melafix/pimafix. PLEASE someone help me, and guide me to healthier tank for my fish. I do have a 29 Gal Bowfront that i'm trying to set up but I have no stand or top for it. It's been a project in the works for quite some time I've got a filter and heater but don't think I can work with that, I'm still a noob. HELP ME TO SAVE MY TANK BUDDIES... PLEASE...... Thx!
