Dwarfs are typically very shy, nocturnal creatures and their lifespan is generally only 6-8 months, sometimes longer. They can be kept pretty easily though. They don't tend to try to escape like most of the larger species. Should be kept in at least a 20 gallon, and by themself. They will eat fiddler crabs, hermit crabs, and sometimes snails.
If it's from the US eastern coast it is probably O. mercatoris, which is a large-egged species and the hatchlings can be raised. Most wild-caught female octos will lay fertile eggs.
Something to consider is that they are only active at night, in the dark, and you need a red light to view them with. Honestly they can be pretty boring unless you're just absolutely crazy about octos. Larger species are much more active.
 
wow a 6 to 8 month life span that sucks. i thought he looked pretty cool and was thinking about getting him i dont think i will sine they are short lived. thanks for the advice.

If you can get more information about it that would be helpful. Just because it's small doesn't necessarily mean it's a dwarf. Sometimes they are labeled as dwarfs and turn out to be mid-sized octos.
Yes, 6-8 months does suck. My first octopus was an O. mercatoris and he lived for 4 months, no telling how old he was when I got him. Still have him though..

... in a jar of formalyn.
They're fun but guaranteed to break your heart in the long run.

None of the ones small enough for a home aquarium will live more than 2 years max. Most live a little more than a year on average. A member on TONMO has managed to raise the second generation of mercatoris babies after her first one laid eggs and she has kept most of the second generation for an impressive 11 months, which is unheard of.
If it fits in a hermit shell it's probably still relatively young.

I used to work at the Shedd Aquarium in Chicago for two years...every octopus we had died after six months :(
