Moving live rock with fish/inverts/corals in the tank
 

Is it ok to move one of my big live rock chunks around in my tank or is this going to screw up my biological filter? I have a clownfish and and cleane shrimp and some hermits and snails plus corals but none attached to the rock.. Anyone?

You move the sand you can release h2s phosphates and such. Be careful.

Sand bed
 

Hopefully this piece just Sits on the top of the sand. I have a bad feeling that a turbo snail and a crab have gotten trapped in this rock and have died so I've got to move it. Haven't seen them in a few days which is weird for the turbo snail. Should I shut the powerhead and hob off when I move it?

if your system is fine and been setup for quite some time you shouldn't have a problem and its best to have all pumps off for the time of move.
If your system is large enough and could handle the bioload I wouldn't worry about a single dead snail or a crab. if you worry about and individual invertebrate, then you will be spending more times moving things around then enjoying your tank.
Just like Titus99 said don't stir up the sand as that is where the h2s will be released from.

Small system
 

I gOt a 10g nano reef and it is 2 months old (started with fully cured lr and used water from a huge reef system) that's why I need to find the dead animals.... Small system not much room for mistakes, that's why I'm asking. Man I gotta talk the wife into Letting me get a 55g

That is true for a nano system you would want to find the critters.
1st try to detail looking at the rock or sand,I mean try finding the critters before moving things,...and at the end do not disturb the sand,good luck.

Yep
 

really there isn't anywhere else they could be because the other rock work is more or less flat. I'm almost temPted just to take this chunk of rock out of the tank but then I will only have like 6lbs of rock in the tank.

wtf
 

cant find the turbo snail anywhere, its not like its a small snail, but i cant find it. I have zoas, a frogspawn, clownfish, a couple hermits, 1 more turbo snail, and a cleaner shrimp in the tank. If its dead and in the tank is it going to affect my tank and crash it. I really dont want anything to die.. what to do?

I wouldn't worry, the hermits and cleaner shrimp will dispose of the body.
