On of my white cloud mountain minnows has a large red bump/sore on its side above its stomach i have quarintined it in an 8g tank an put in sone king british desease clear. Any help please!

well...a pic would be of help...
i am not very sure about this...but my guess would be ulcer/septicemia...which is essentially bacterial...
so u could treat the tank with a broad spectrum antibiotic...
up the temp in the qt and add a little salt to ease the osmotic pressure...

someone with more info will soon come along...
