Thanks for all the replies, the advice is well appreciated being a

The Quarantine tank is a small 20 litre (5g). I am not using any
filter, just light aeration. Not sure if this is suitable for a
Quartantine tank?

I will be moving just one fish, a M.lacustris male. He has developed
a large red lump behind his eye. It seems to have come up almost
over night. I am worried my warm tanks may have brought it out. In
Brisbane, Queensland my tanks can get above 30c this time of year.
The tank in question is 29.4c right now. I read in Harro's book that
higher temperature can trigger Ulcers. But short of installing
chillers on every tank or running the air con 24/7 I can't do much
about it!

I guess it comes down to more water changes and lower stocking
density. I must admit I had not changed the water in this tank for
over 2 weeks. I try to do 50% a week but is this heat I become
rather slack!

The guy at my LFS said it would have been brought on by stress from
high temps and fighting males. This sounds right to me. The males in
the tank have been sparring alot. He also suggested using 'Bactonex'
as a preventitive. Anyone use this?

As for the treatment of the affected fish, I might try Melafix or
