So for a few months, off and on, my Dalmatian Molly would hang out at the bottom of the tank just flapping her fins and tails as if she was swimming. She would just chill at the bottom for hours. And just today she started swimming around with the back of her body to the left more. She only is swimming like this. She doesnāt wave her tail around normal anymore. Whatās wrong? What should I do? I did some reading of other discussions and Iāve concluded itās the shimmies for the first of her symptoms but Iām worried and canāt find any information about the strange swimming she is doing.
