Ok.
So I stopped buying dwarf gourami's a while back cos they kept getting parasites and dying. But I still have one who was a trooper and stayed alive when all others got sick. Today I saw him hanging around the bottom of the tank a bit, maybe trying to hide. Then I noticed two wounds on his face, near his mouth. They look very red, like blood and maybe a little puffy. I don't know how this happened! His tank mates are two regular gourami's and a bristlenose catfish.
Stats are normal (0 ammonia, 7 ph, 27 degrees C and heavily planted tank). Recently I lost my angels, but was told that this was cos they need a 'mature tank' (mine is only 4 months old). My tank is 21 gallons (apparently too small for full sized gourami's). Attached is a picture of my fishes wounds. I never see the other gourami's chasing him. In fact, he used to be the more agressive.
What is it? Sorry for the bad photos. I can't focus on him.
Please help. I don't want any more fish to die...!
Update: Just noticed he has a clear stringy thing hanging from him...probably poo but looks thinner than usual and of course clear. Should I give him peas for constipation? Poor little guy.
