I just got a SAE (Siamese algae eater) yesterday. He has a very jerky way of swimming. I know these fish don't really have a swim bladder but he seems to almost throw himself around the tank. He almost seems to be crashing into the glass. I don't know if he is eating algae off the glass or if there is something wrong with him. He's absolutely the most ungraceful fish I've ever seen. He has been schooling with an amazingly large otto (over 2 in). I am planning on getting him a buddy when lfs has one available. Can you SAE owners tell me if your fish swim like this??
