i just brought a tropical blue lobster for my tank it is so damm cool :P any suggestion on how i could hand feed it and what food would be best for this?

I had one, and I was never able to hand feed it. It was always hiding, and the one time I tried to hand feed it, it pinched me, it usually ate whatever left over food my fish didn't eat, and occasionally i fed it bloodworms and such. Be careful with them though, as mine ate a lot of my fish, including a $40 pleco. Also, they are extrealmy good escape artists, they can get out of your tank and disappear. I have had two escape, never to be seen (or smelled) again.
