My female betta Kissyboots has been getting stuck behind the filter tube lately. She used to swim there all the time when she was...thinner. She's kinda fat now and will occasionally get stuck there. I don't know why she keeps doing it. I've had her for almost a year and she's like twice the size of my newest male betta (Finfin.) Uh oh! She's doing it again right now! Any suggestions why she's doing that? I don't want her to die there...
