What is hapenning to my Ram?

I have looked at pics of HITH affected fish and I am almost certain its the same thing that affected my fish. I've read about possible causes and cures but there is nothing about it being contagious or not. Can anyone please shed some light on this? I just want to be sure I don't have to treat a whole tank. I will change 50% water and treat with melafix for a few days just in case.
 
it depends.. i personally feel some fish are prone to it others not. I had a single angel get it in a tank with 6..none of the others were affected.
with HITH flagellated protozoan are associated.. it is suspected they are affecting the gut and nutrition uptake.
with HLLE it is suspected poor food or nutrition uptake. protozoa are not usually associated with HLLE.
 
I found the ram dead this morning. I watched the remaining 2 rams closely and there is no abnormal behaviour and no sign of any illness on them. I will keep an eye on them.
I checked my nitrate again and I got a reading of 5. The next water change is due on staurday. So I don't think it is the water quality. I have read a mention about electrical current in the water causing this. I have an electrical CO2 generator in the tank. I will check that angle as well during the weekend.
 
Sorry for your loss.. But This was NOT HITH. Hith Does not swell.. It pits.

Was the head exploded? Did you get another picture. The redness in the first pic where the swelling was.. Strongly calls out Parasite.
If that area is now a pit I would really watch the other fish!
 
The head did not explode. I am keeping a close watch. I will add melafix just in case after the next water change tomorrow.

what parasite are you referring to?
HITH does swell just before the pustules burst. HITH has strong resembles SX to pimples in human
also with open wounds there is a high risk of infection which will cause redness.

BTW HITH has been associated with flagellated protozoa.. a parasite. treatment is recommended with metronidazole but I believe it is an antibacterial.

have you studied HITH/HLLE?

it does appear there are pits/tunnels(HLLE)
the first pic is typical of HITH.

to me, it looks like he had worms in his head. I lost a ram to this myself but due to me not knowing what or how to treat in time, he died too.... afterwards, I could probably have used Levisamole Hydrochloride.
 
I have gone through some materials about HITH on the web and seen the pictures. They look identical to my ram except the swelling in the eye. None of the other fish have shown any sign of any desease so far.
 
Tough loss. It does remind me of worms though.
