Tank information:
65 gallon (36" long) planted with small smooth gravel, ph 6.8, water soft (peat extract), ammonium 0, nitrite 0, nitrate 10 ppm. Water changes 50% every 5-7 days.
Basically the cory seems happy and is very active, I'm just concerned because I have never seen such a fat belly and the fact that it was not that way a few weeks ago?
Is this something for me to be worried about?
