I haven't been able to identify the little blue octo I saw in the LFS today. His mantle is about the size of a nickel. At rest he is a dark gray color with blue, very small spots all over. Almost teal colored spots. His tentacles look long for his size. I'll try to get a pic tomorrow but thought I'd throw the description out here in case someone had any ideas.

Thanks!

If you are not pulling our collective leg, do some reading on blue rings and see if you find photos of your mystery animal. Blue rings do not show the rings unless aggitated but anything small with blue "spots" is likely something to avoid and the shop keeper needs to understand that the animal is dangerous. At TONMOcon II, the aquarists had to euthanize 20 that came in unordered and she made a comment that she would not have known the animals were blue rings when they arrived.

Most of Roy's great shots show the animal in its most attractive state.
I did a quick search to try to find one NOT in an aggitated state without too much success but did find some Teal coloration:

This video shows several of the species but trying to match your find would be difficult

Here is a picture of O. Bocki that I found on google image. Is this what your mystery octo looks like?

Gee that got everyones attention! LOL! But no, I'm not pulling any legs here. It does look similar to that last pic but the blue spots are more uniform over it's body. The LFS says it's not a blue ring octo but . . . .

He's a tiny little bugger. I go by every day after work (5pm EST) so I'll snap a couple of pics on the way home and get them on here this evening. If I didn't have my hands full with cuttlefish chores I'd probably pick him up. (So long as it doesn't turn out to be the blue ring demon!)

I read somewhere that not only do blue rings secret the venom into their saliva, but are also able to squirt it into the water like an ink cloud. Not really sure how that works, but I read that they can do this to a prey animal to subdue it without having to make physical contact. If this is possible and it happens in an aquarium, then your water is now filled with venom and it is no longer a matter of not getting bitten but keeping yourself and anything/anyone from getting the venom water on or inside them. Just something to think about if for someone thinking about keeping these.

That is soooo terrible. Those little guys didn't ask for that. I know they were probably just acting for the "greater good" and not wanting to risk any injuries or deaths, but that's still terrible. Twenty animals died for no no reason.
