I have a fat Neon Tetra

[Kryten]

I feed my Neon Tetras with frozen blood worms twice a week which go down a treat. The tetras always have a little bulge in their bellies after feeding time, but one this eveing is huge, much larger than all the rest and isn't a bigger fish than the rest

Is this likely to be a fish that has simply overeaten or could she be pregnant?

Kryten,

Neons are egg layers so no chance that she's pregnant

It is possible that she is egg-bound but I have no idea how to tell. Is your water hard as apparently this can cause problems with Neons....

Cheers, Eddie

I dought pregnancy as told above they are egg scatters.
If over eaten, cut food out for a few days and symptoms should subside.
If no change watch out in case it is internal infection which will spread to others if unchecked
