Here’s a video and she did burrow but her head was exposed and I spooked her out of her burrowWas she able to bury? I agree, the new video does show she's having a buoyancy problem. I had a femininus delivered that was swimming that same way with her head down. She didn't get as bad as Tamberav's wrasse did so after about a week of feeding her brine shrimp like the others suggested her swimming corrected. Then I switched her to mysis and LRS fish frenzy to pack some weight back on her. I got lucky with mine I hope yours pulls through too.
