This afternoon my female clown started swimming very erratically. The last few day's she has been very normal. She spawned a day or two ago. At lunch time I came home and fed the tank and I remember her being normal. Now she is acting like she can't keep her back end stable, maybe a swim bladder issue. She does look a bit swollen around her anus and it appears as though she has to poop, is it possible she's just a little backed up? Should I pull her and QT her for a few days?
