Ok so I have had Stabby our BGK for just under a year and he has always been happy and healthy, But 6 months ago I was given some Convict fry and not thinking much of it I threw them in the tank with my BGK. when the 3 convict got larger (still smaller then Stabby) they started to pick on him and I imediatly removed them from the tank. this was 3 months ago. Stabby still has a wound on his side that wont heal, I have tried water changes, aquarium salt, melafix, primafix, I took out all the decorations so he couldnt not rub it off, and I recently added them back in thinking maybe the stress of nowhere to hide was the trouble.
Im out of ideas to help... can anyone help us out ? I dont want to just get a new one, we love stabby
