Thanks. The rock you see is TBS. I also have some GV below.

I just confirmed that the clicking I've been hearing at night is a mantis. A very nice looking two incher. Should I tear the rock out and look for the goby? Try to catch the mantis ASAP? I did get three mantises off the rock before I put it in the tank... this one snuck by me. And as I get ready to submit this post, I can hear him clicking away...

One more question, my water is not perfectly clear. I do get some air bubbles in the return water and can't seem to figure out why. My skimmer is two baffles away from the external return pump. Any suggestions?
 
I'll let Slip weigh in on the bubbles since I'm a mechanical idiot.

Regarding the mantis, I would first try setting traps. First, starve the tank for a good 4-5 days. Try a commercial trap (any of the big online retailers sell them) and try homemade traps from soda bottles. Cut a 2L in half and bury the pieces in the sandbed so that the cut rims are flush with the surface of the sand. Bait the bottom with some shrimp or other food and see what you've got in the morning.
 
Coming along nice, I like the rockwork.

Seems your sump doesnt have any baffles that force the water down, or can I just not see them in the picture?

Anyways, you can add a couple more baffles pretty easily. Just find some cheap acrylic sheets at home depot, cut them to size and wedge them in place (you can silicone them in if you want, but if they fit well enough you dont need to)
 
Looking more closely, I've convinced myself that the "bubbles" are actually the fine particles from the Southdown being stirred up from the bottom. Analyzing the water in the sump shows no "bubbles." The sump water is very very clear.

I know I want those fine particles so I shouldn't try to filter them out. Will the bacteria growth eventually weigh them down?
 
How old is the carbon?

You could temporarily run some mechanical filtration, I throw on an AC300 with two sponges once or twice a month.
