A couple of hitchhikers

[Twinn]

Got some live rock for my tank today and heard a snapping sound as soon as I touched it. Sure enough found a pistol shrimp



Also this thing fell off the rock too. Not too sure what it is.



Pod maybe?

looks like a pod of some sort to me. Is he just curled up?


How big is that pistol??

The second one is an amphipod http://www.xtalworld.com/Aquarium/hitchfaq.htm

I thought it was a pod too, it is just curled up. The pistol shrimp is just under an inch in size. Don't know if it will make it throught the cycle. though.

if you don't like clicking sounds coming from your tank I would get rid of the shrimp.
