Hi all....I'm new here, but need a little help. We have a bimac in a 125 gallon tank. He's been in there for 6 weeks, perfectly happy, playful, hunting well, and in general a wonderful pet. A few days ago he started getting restless, so I double checked our "octo-proofing" but today, while I was out for about an hour, he escaped (I think he found a tiny hole beside the overflow). Anyway, I found him as soon as we got home (he usually comes out and says hi when we come in the door), and put him back into the tank. He wasn't dry and had himself suctioned to the floor - I really had to work him to get him off. He stayed out for a couple of hours, climbing on the side and sitting on a rock, and then went back into his den. When I tried to feed him, he wouldn't come out to eat and I was worried, so I lifted his rock. When he came out, I noticed that his tentacles were about 1 inch shorter and it looked like he could only use about 5 rows of suction on each one. I'm pretty sure he is chewing off his tentacles, and the two shrimp in the tank with him are already starting to try to "clean up" the dead flesh. Is there anything I can do for him?? Is he definitely going to die? Has this happened to anyone else? I also have a second question. I have 2 quarter sized bimacs in a smaller refugium (sp?). How long before they need to be separated? Any and all opinions and help please, I feel sooo horrible!
