Help - Platty not balanced
One of my long fin platty is having problems with her balance. Her backside is floating more than the rest.
She stopped producing babies about 6 weeks ago and now this. She is 4 years and 3 months so I'm worried that it is just that she is getting old. She will come up for target feeding and if my hand is in the water she will swim up into it (she has always done this because from a fry I used my hand to move her when cleaning the tank rather than netting her). The difference is now when she gets to my hand she appears to just sit and rest as long as my hand is in the water (yes, very anthropomorphic comment I know).
All the water parameters are fine, my other platy and plecos are still breeding like crazy.
Attached is a picture of her. It is grainy because she is in a plastic 2 gallon temp tank while I figure out what is going on.
