So yesterday I go to LFS and decide to get a small blue hippo tang. In the tank he is swimming around looking good. Bag him up bring him home and sit him in the tank inside his bag to temp aclimate. When I move him to the bucket I notice he is swimming weird, flipping over rolling and swimming upside down and vertical. (I have not implemented a QT process yet probably because I haven't lost all my fish to a parasite). But I am setting one up now and I'm not sure what I should try to treat. He is 1.5-1.75 inches long, I do not see any white spots. I do notice his respitory rate seems elevated compared to the other fish I have (appears to be about 2-3 times per second). If I put a baster in there and move a little water around he starts swimming in a flipping motion for a few seconds and then just floats. What are everyone's thoughts on what this could be?
