Glad you bought some batteries! Good shot of the texture but I am afraid that you would need to borrow Thales as well as the camera to get the quality of pics he posts
I would try some live crabs or shrimp rather than counting on the snails and hermits (none of my mercs will touch krill, hermits or snails but they are more pickey than the larger octos). Small crabs seem to be the most widely accepted.
i feed him some raw shrimp, i think he ate some of it but its hard to say, he crawled off with it where i couldnt really see him, then finally found it laying in the sand it looks like he ate some of it, but like i said its hard to tell. I am going to order some crabs. "Should have already" how do you feed fidlers? i mean i am going to remove the pinchers but do you just drop them in the tank? "want they die if not eating immediatly?" or do i need to drop them in front of him?
I would throw the fiddlers in one at a time where the octopus can see you dropping them in. If it's hungry it will immediately snatch the crab up. If they seem small you might drop in a second one after the octo is finished with the first one. If you put in several you run the risk of them dying in the rocks where you don't know they are dead and they foul up the water.
