hi guys. would like to ask your help and opinion regarding my stingray. It has been acting funny and strange for about a month now. I have attached a video of the stingray. It looks like he is having a hard time controlling his disc and is flapping wildly. he seems to not able to control his movement too and has a hard time bringing down his disc. Water parameters are fine and i have moved him to a 75 gallon hospital tank. His eating and appetite seems ok too and would readily eat the shrimp and fish bits that I give to him. Was wondering if anyone has any suggestions on how to treat this stingray. Thanks
