Haven't been on the forum for a while. My wife recently noticed one of our neon tetra's is extremely bloated, looks like it might explode!
Ammonia is about zero
Nitrites are zero
Nitrates was 10ppm, but we did a water change today, 50%
Tank temp is around 26 Deg Celcuis
Tank is about 250L and running for more than 2 years
I'm using a Dophin C-1000 canister filter
There are about 3 neon tetra's in at the moment, 2 kuhli loaches, 1 plecostomus, 2 black neon tetra, 2 cory cats and 2 hillstream tiger loaches
Have had the fish for over 2 years now
No new decor has been added.
Any help would be appreciated!
