I have a 10-gallon aquarium, freshwater, with a nerite snail, a red swordtail, and an albino cory catfish. The water quality is fairly pristine (if I do say so myself), although it is extremely hard. The GH
is around 150-180. My problem is that the cory has a huge bulge in its belly, towards the front of its body. I've had it for around 10 months now, and it has had no other cory companions. So, is it pregnant with unfertilised eggs or something? Is it bloated or sick? I've been feeding it 3/4 to 1 algae wafer every other day, so is it just fat? Please answer soon, as my cory is nearly too bloated to move.
It was hiding when I put up this thread, so I couldn't get a good photo. If you need one, please just ask.
