i'm so frusterated right now!! my red eyed tetras just appeared with a fungus 2 weeks ago out of no where. no reason they should have got it, haven't done anything different and they didn't have any other injuries. my one bala sharks mouth is all bloody and red and swollen for about 2 weeks now but seems to be staying alive still. doesn't even look like a mouth. once again, never did anything different. my betta seems to be going down hill...don't know if its old age but hes not doing so well. ugh, this is just so frusterating! i haven't done anything different at all. i do my weekly water changes all the time. params. are all still how they've always been and i don't have a qt tank to put the sick fish in and even if i did i don't know how to treat them?...this is just getting ridiculous:wall: could someone help me with these problems.....please?? how do i treat them considering theres other healthy fish in the tanks and theres corys in the one tank??
