obviously hes not in a reef tank so no you dont have to QT him but sometimes its best if you do.depending on the size tank you have him in now.you can use melafix in your main tank remove any carbons you have first add the melafix for 7 days it wont harm your fish its a natural product and can be removed with carbons.thats why i use it.depending on tank size matters becuas of how much you have to use in one single dose QT tank take a smaller dose so lets costly.but i have used it many times for the same symtoms and i always worked well
malafix can be used for the removal of : tail and fin rot,open red sores,open body wounds,eyecloud pop eye and mouth fingus ,body slime.
pimafix can be used to cure fungal infections on body and fins also treats bacterial infection for internal and external.such as cotton mouth and body fungus reddening fins and body.these 2 products can be used together.both natural products.after 7 days of treatment do a 25 % water change hope this helps
