Anyone know what species of cray this is? Its roughly 4inchs tail to claw, and a bit aggressive

looks like a marbled cray with that color variation

Its possbile, but im not sure on that. It doesnt have the same pattern or coloration of any marbled cray ive owned. This blue one has a purpleish color on the tail tip

I would guess Cherax quadricarinatus

Looks like a freshwater lobster to me also. Here is a link http://www.liveaquaria.com/product/prod_display.cfm?c=1075+1662&pcatid=1662 for info.

Also a possibility pleco, although the the cray/lobster i have doesnt have the same bright blue color as that blue knight lobster

if this was housed with marbled crayfish, would they kill each other?

It is a Cherax quadricarinatus, which is not a dwarf crayfish species, they can be aggressive. They are from Australia, where they're commonly called a 'Yabbie'. I used to breed them.
