I bought a young betta that was approximately 6 weeks old about 2 months ago. He has not shown any signs of health issues prior to what seems like this state of partial paralysis. When he swims, it is as if he only has control over his body from his pectoral fins up. The entire back part of the body makes a slight curve to the left and does not move. Moreover, it appears as though his upper body is more developed than the lower portion. Any explanations or theories? Suggestions on possible treatment or relief?
