ok. so maybe eggs because she seems totally fine with cuddling with the other cories at night on the floor. i have sand substrate. also another cory did 2 little flips because maybe he was stressed ebcause there were so many people fighting over food? or something else... he seems totally fine though.Maybe she does not like the substrate, Something irratating her?
Any injuries to belly area?
I have a fat female at the min who wont swim right to the top but cant find a reason for it except for possible egg carrying
