Good Blimp or Bad Blimp?

[Helena]

Hello! I noticed I have one very large Zebra Danio. All of the other ones look fine but is this a sign or bloat/constipation, egg holding, or just how they are built? In true danio fashion the little speedy guys are hard to get a picture of. I only feed them every couple days because I try to avoid having grapes with fins. Any help would be greatly appreciated!

Here's a better side by side comparison and my water quality

She looks like she is holding eggs. I bred these years ago though so I’m going on old timers memory. 
 

Grapes with fins… oh my I burst out laughing when I read that. Very creative.

Thank you! I thought my cory catfish ate a lot but man those little Danios will eat themselves until they are perfect spheres and even then try to keep going!

Yea... Same goes for one of my rummy noses. She eats like crazy compared to any other fish I have. So she is insanely fat..... I have been fasting the tanks lately and underfeeding, she is looking better rn.
