Fungus that just won't go away
A while back I noticed my Corys had a bout of fungus, mainly on their lower fins.
I duly dosed the tank with some anti fungus treatment and it cleared up. Only problem is that every time I stop the treatment it just comes straight back.
I think the fungus started when I was spending quite a lot of time in the week working away - my automatic feeder was dropping the food into a different corner of the tank to where I usually feed them & I think I overloaded the feeder. However, this was mid October - I've cut down the food accordingly, kept a close eye on water quality but it just doesn't seem to want to go away!
Any ideas for zapping it once and for all? I'm getting a new tank very soon & don't want to transfer any disease when I move my Corys.
Incidentally, on the topic of fungus treatment, it's always wise to take heed of the bit about the treatment reducing the oxygen content of the tank - I found my Corys gasping for breath and dashing for a gulp of air every minute after treating for a week or so ... easily resolved by an air pump but can't have been nice for the poor little mites!
