I just had a white cheek tang get delivered from Pete’saquarium.com and I’m starting the drip acclimation. He’s swimming erratically with his head and eyes out of the water. I understand shipping is hard on them but I’ve never seen this behavior from any tang before. Will he be okay after settling in? Salinity in his bag was 1.020 and temp was 71.2. No heating packs in the box. Is this a swim bladder issue? Blindness? Thank you for any advice.
