Hi, the guy I buy fish and inverts, nsw, and LR from chucked a smallish BTA in with my fish purchase (lol which was meant to be a royal gramma and is indeed a royal dottyback). I was going to wait a little longer for nems but the perimeters are good. I put it in a next of small rocks the first night and it got itself over to the other side of the tank instead of attaching, I found it in the morning face down in the sand. Put it on a rock and it looked happier. Today found it wedged between and under rocks sort of on its side, not extended at all but alive. I know it's best to let it settle on its own but also am worried if it's not happy and dies it could poison the fish. any advice? Thank you!
