I just got a bimac yesterday. Dripped him, got him in my tank. He immediately went to the bottom and laid against a piece of live rock. Breathing hard however seemed to be o.k. This morning he is still alive and breathing, however has a bit of slime around him with sand stuck to it and has not moved. I was happy he made it through the night however I am worried. Would that just be a stress thing? Also when and what should I try feeding him if he recovers. Salt level is 1.26 and the tank does not have RO water, however I do not really use it for any of my tanks with no issues. Has been up and running for 3 months awaiting the octopus. Nothing else in there.
