No skinny fish with bent spines. Symptoms have mostly been lethargy, stopped eating, died. (internal bacteria?) but this seems to be sorted now. Only the DG has a problem (these ulcers and fins) and my catfish with the ulcers has still not recovered.
I have used the following meds and none have had any effect:
Protozin (anti bacterial)
Wormer Plus (parasites, worms etc.)
Interpet no 9 (anti internal bacteria)
Melafix (broad spectrum anti bacteria)
I'm really at a loss, I think i've used every medicine in my LFS.
Does the fact that he is scratching it help in diagnosis? I guess that probably leans towards it being some sort of parasite/bacteria right?
