One of my larger glofish currently looks significantly fatter than the other 7 I have. The belly looks almost boxy in shape. I’ve tried taking pictures, and they’re all pretty terrible showing what I’m talking about. What do these fish look like when carrying eggs? Do glofish show gravid spots? Is there any way to easily sex them? If it’s not carrying eggs, could this be a sign of a health problem? I’ve had them since January, so they aren’t new to the tank.
