thanks all.
my pod population is sweet, but i'm waiting to get my real fuge working before i do anything mandarin wise. I have pods infesting my carbon bag i have in my sump LOL.
I have a nice sand bed on half of my tank where my pistol shrimp has moved ALL the sand from a 1/4 of my tank. its probably 5-6" deep, i started with a 3" sand bed and it has been re-landscaped by the pistol, current, and clowns to deep on one side, and shallow on the other.
So i guess the only real possible conflict would be the shrimp goby and the jawfish if either is territorial and decide to live in the same side of the tank.
