Odd little shrimp

I was injecting some aptasia with a baking soda solution today and noticed a little shrimp dart out of the hold one was in. I've tried to get a picture of it but it is only about 1/4 inch long and semi transparent. It's guts are visable along its back as a darker brown stripe.

It reminds me of a slightly hunchbacked mantis shrimp to be honest. I cant tell what its claws look like or eyestalks.

Anyone have any other ideas?

PS, I'll work on getting a picture when I find it again.

 

Probably just a mysis shrimp.

 

i have a lot of little shrimp looking things i've even seen a couple green ones. anybody got any ideas on what the green one could be. as far as i know there all just a link in the food chain and are harmless please correct me if i'm wrong.

 

Everything eats something and is eaten by something. I'm sure that this little guy with get snacked on when I eventually add fish or bigger inverts to the tank.

 

mysis and brine are really common in displays probably what you saw

 

Could simply be a large amphipod as well.
