I've looked up everything I can find about betta illnesses, but I haven't found anything that relates to my fishes problem. First, let me give a bit of background on my fish. It's in a 3 gallon tank, room temperature water, filtered, with 2 ghost shrimp. It's lived with the shrimp for about 2 months and they haven't given eachother any problems. But 2 days ago I noticed that my fishes body is contorted. At first I just thought he was fighting his reflection, but I've been watching for a couple days now, and the best way I could describe it is that he seems like he has a crick in his neck. He's turned to his right side, which is making him swim funny, so he keeps getting too close and bumping into the glass, which then scares him so he freaks out and kind of flops around until he gets away. Nothing I can find online is helping. Does anyone have any suggestions?
