I got a new mccoskers about a month or so ago, and the other day I was moving him to my display tank. I drip acclimated him then went to bed which I planned to sleep for an hour, but ended up sleeping the whole night and totally forgot about him. I work up and panicked went quickly to the bucket and saw him laying there breathing heavily. I put him in an acclimation box, and put an air tube inside the box. Thankfully he’s doing well and eating!
