I've only been keeping fish a little while so I'm definitely rather new. I noticed my black female bubble Molly swimming in circles about an hour ago. Other then a kinked tail she seems okay. It seems more like her tail is stuck to the right. All of her fins are moving fine. She's not hovering at the top and other then when she is hit by the current of the filter, she seems to get around fine. O currently have her in a quarantine tank because the other mollys immediately started pecking at her. She was fully capable of swimming away (thou her tail fin was still kinked) but i didn't want her stressed. Water parameters are good and none of her tank mates are having problems. If anyone can tell me what i might be looking at here, please help me.
