Hi all,
I have a 120L fully cycled tank with the following parameters : 0 Ammonia, 0 Nitrites and 10ppm of Nitrates. In the tank, I have 5 gold barbs, 2 platys, 2 denison barbs and 2 amano shrimp.
Over the past 3 weeks or so, one of the denison barbs has become very dull and skinny. It rarely swims around the tank with the other fish. Instead it rests at the bottom of the tank amongst the plants or beside the filter unit. From time to time, it rests beside the filter unit facing the gravel below. I have also noticed that it moves its gills more frequently than the other denison barb.
It seems to spit out a lot of the food it consumes, particularly larger pieces of flake food. I feed them blood worm as well and I haven't seem it spitting them back out but it certainly doesn't have the same appetite that the other fish do.
Before this change in behaviour, I noticed that the other denison barb, which is well over twice the size of the skinny one, was chasing the smaller barb around the tank.
Anyway, anyone have any advice on what could be going on here? I am thinking parasites. I have checked its fins, mouth and scales and can see no obvious sign of disease (fin rot, white spot, redness around the gills) but the gill movement and spitting of food have me thinking parasite.
Note: The denison barbs were introduced into the tank 2 months ago.
