Or at least tell me what I am looking at 
After adding my fishy friends, I decided to start running the lights. I'd been wondering why I'd not gotten really any "uglies" at all... well, a week of running the lights stopped that. Kinda amazing how fast things happened.
Anyway, this is what it looks like now, I've adjusted the white balance to reflect what it looks like to the eye as best as possible.
As you can see I have... uh... brown something... growing. Mostly on the rock and rubble, but a bit on the sand as well. The sand in areas with a higher flow has less growth.
I've also noticed that the upper central area of rock seems to have less... and this is where my 2 emerald crabs are most often spotted, it seems to be their "home turf". I assume they are eating it, and keeping it comparatively clean.
I see the (teeny tiny) blue- and scarlet-legged hermits on the rest of the rock; either they are too small to make a noticeable difference, or they aren't eating it at all.
There are also a couple of Ceriths about, and 3 Nassarius which are keeping themselves to the sand, and occasionally the glass.
in a couple of pictures, you can see a profile of the sand... it seems to be forming some bubbles of some sort... could this be the Nassarius, since they are borrowers?
I am assuming this is all natural, and an expected part of the tank balancing out, so if y'all see something that is a big red flag, let me know!!
Should I add any more CUC at this point? 2 emerald crabs, 2 each crimson-legged and blue-legged hermits (both wee dinky), a couple of Cerith, and 3 Narsarrius, in a WB 70.3 (just under 50g display vol). The tochus snails I bought didn't make it, and went to the great snail graveyard in the sky (backyard),
