Default Skin Ulcers?

Anyone,

I have an Amazon tank with three keyhole cichlids, two young angelfish, a
few cories, and a few small tetras.
Recently the largest keyhole developed a nasty looking ulcer on the back of
his head. He hides a lot, so he
could have had it for a few days. I did a 50% water change, cleaned out the
filter (Eheim), added some salt,
and turned up the temperature a bit, but he died within hours. I just
noticed a similar lesion near the tailfin of
one of the other keyholes. Any ideas?? Anything else I could do??

Pictures of the keyhole that died (the current ill one won't come out for
pictures):

Thank you very much,

Default Skin Ulcers?

Ulcers are primarily caused by baterial infection, which is most often
caused by poor water quality. Treat affected fish in a hospital tank
with a gram negative antibiotic like kanamycin, tetracycline, anything
with furan, or maracyn-2. These antibiotics will also kill the
nitrifying bacteria in your tank. Most of all, keep up with weekly
water changes!

Thanks Chris,

I ran Nitirite, Ammonia, etc tests but everything looked fine.
I am trying an antibiotic treatment with regular water changes.
Shall see what happens.

Thank you,
Kevin
