Fatal Mystery Illness

[kali426]

Hey guys how are you all? havent been here for a while WAT UP CRACKER!!!!!!

i would like everybodies advice on what this illness by bettas have been dropping dead from is.
i starts out as a white fleshy sore which is also quite lumpy and will almost always be on both sides
of the body if its near the tail region.i have treated this with my usual meds to no effect.
the sore simply gets bigger and bigger til they die,though in usually euthanise them before that stage
as it looks like it would feel very uncomfortable.the medication i use is the same i use for all
my fish wounds MELAFIX and aquarium salt.this really worries me because my only surviving
male and the best male ive ever had by far(see avatar) has managed to survive but i know once i see this wound on him hes dead! should i decontaminate all my equipment?if so whats the safest method without bleaching? does anyone know what this illness is called and an effective remidy before i loose DREAD my last male betta.if i lost him id probably never get another betta.

There are several things I can think of that it might be. My best guess is a bad bacterial infection. It has gained momentum and is undoubtedly spreading through your implements. Boiling, chlorine bleach and salt are the usual disinfectants. Some things won't boil, like plastics. Salt is for fungus and parasites. Chlorine kills almost everything. Just rinse after a good soak and scrub and let air dry. It will be evaporated after a day or less.

But you do need a good diagnosis from a good diagnostian. Try posting in the emergency also. Or wait until Random or another very adept diagnostician sees your thread. I would post in emergency and try to get Wilder's attention. Be prepared to give accurate water stats and a picture of the affliction.

I would certainly add some aquarium salt to the remaining tanks. If you have any IAL, I would add that too.--Oops, I see you have already added the salt.
