Black Mollie exploded?

[robdollaz]

I have 4 black mollies. Ive had them for about 2 months. My water temp/pH/amonia levels are all good.

None of my fish have any signs of disease.

I did notice about 4 weeks ago, that one of my mollies was getting a huge belly. I thought it was pregnant, and so did my sister. This morning I was looking in the tank, and saw it was at the bottom of the tank, dead, and looked like it had exploded.

It showed no signs of being stressed, or anything.

Any thoughts?

It may have died in the night and the other fish tried to eat it.

Is there a fish disease that would cause a fish to have a huge belly?

It has been swimming and acting normal, with all the other mollies.

The only agressive fish in my tank, is another molly, who chases my dwarf gourami's, but he doesnt bother any of the other fish at all.

There are plenty of diseases that cause bloating but I would wager she was pregnant, given your stocking list that she was most likely bullied by one of the other fish in your tank (even if you didn't see it).

Live bearers should be kept in 3F/1M ratios because the males will harass the females incesently and often stressing them to the point of death. Unfortunitely with that ratio your tank will end up FULL of babies in no time so usually I suggest only keeping one gender in a tank. Also because these fish a cronically over/inbred they are not nearly as hardy as most would thing and often succomb to stress alone.
