Hi everyone, I'm hoping that someone out there can give me some help/advice in dealing with a sick gourami.I recently bought a second hand 6ft tank including fish.When I checked what fish were in there I was surprised to see 4 Blue gourami and various tetras being kept with tiger barbs and cichlid (everything I have read up on has said that the barbs and cichlid would nip the gourami).Anyway I seperated them straight away, cycled the tank, amonia/ nitrate levels at zero and then added the fish.All the other fish in the tank look very happy/healthy except one of the gourami who is resting at the bottom of the tank and has very tatty fins and red in his side fins.He is still eating properly, swims normally when I approach but just doesn't look as healthy as the others.I have added stress coat and checked amonia levels in the tank to rule out poisoning but he is still looking under the weather.My initial thought was that he was picked on by the cichlid/barbs especially as they were all kept in a relatively small container for transport before i realized what was in there combined with the general stress of the move and change of home.Does anyone else have any ideas or suggestions on what I should do??
