Ever since I got my wrasse he didn't swim smoothly. He swims with a bobing motion. Don't know how else to describe it. Looks like he had swim bladder when I first got him home. He is swimming upright and fine except for this swimming motion. Looks as though his front 2 fins are slightly eaten away, maybe from a higher level of ammonia from where I got him. Wondering if this is normal behavior for a marble/ checkerboard/ hortulanus wrasse? And does he look constipated?
