+1. HOWEVER she also could be bloated. The way to know is if she is having eliminations (a.k
) If she is, she's not bloated. The fullness just means that she is old enough to be carrying eggs. This happens when fish mature so it's not like you created a perfect spawning area for this fish so she grew eggs. She could go the rest of her life without spawning and just carrying the eggs. The good news with this is that you have kept your fish healthy enough to produce these eggs.
Just so that you know, the only fish that can get pregnant are the livebearers (Guppies, Platys, Swordtails, Mollies, etc.) The rest just have eggs which need to be fertilized, outside the body, by a male of a similar specie (with some exceptions) if they are to produce young.
Just a little FYI that should help you as you go along in the hobby.
Hope this helps...
