Unfortunately the octo I received 3 or 4 weeks or so died. I know for a fact it was eating fiddlers and looked healthy up until I found it dead. On a more positive note, I recently got another octo. It is much smaller at maybe 3" tip-tip. It's mantle/arm ratio is much larger (legs aren't as long) than the last one. I have no idea on the ID but I will try to get pics up once work slows down a bit. Anyway, the new little guy has been very personable! I was worried it was a dwarf but based on its behavior alone, I don't think it is. He is already taking food from me directly and is ALWAYS watching me from his shell. He will bat at the tongs if I come close to his shell. I have caught him imitating a hermit crab climbing on liverock (he was shaking and balled up moving down the rock). Sorry if I accidentally start using he/she, it's a bad habit. It will also kill fiddlers and stash them outside the shell. I know he is eating them, but it's at his pace. He will always have atleast one dead one there and if I try to take them out he bats at the tool. I think he's upset he can't jam them into his shell, because I've caught him trying it 2 different times. The fiddlers are just as big, if not bigger than him but he has no trouble handling them! Sorry for the novel but it has been a while since I left an update. Plus my new octo has so much attitude!
