Fat lazy Danio...wats up??

[mariposa]

Ok I have three Danios in a 10 gal with a betta. They are usually highly active but I've noticed one who is noticably fatter and slower. Not swimming as much with the others. Still swimming and all but I can tell a difference. Its hanging out in some plants and taking breaks. I'm wondering wat the heck is going on. Just wondering if you guys might have an idea of what is wrong with my fish.

For a good part of the day, danios like to find their favorite spot and just hang out and relax.

I also have danios, and they do like to relax. They especially like to relax if the water quality is good, so keep up the good work. My i.d shark also relaxes ALOT. He'll just swim around for a bit then plop on the gravel for a bit, then surf around some more.
