Here's how I'm setting up one of the cryptic zones. I figured the a-frame eggcrate and live rock rubble zip tied to it would allow for the most surface area for sponges and tunicates. I still want to order sponges from tyree to seed things though.
The other cryptic zone tank has got some live rock in it. Mostly a mixture of Tatoka and Marshall Island live rock.
Just a small red clown goby. I would of waited to put him in, but he kept going over the overflow in my coral quarantine tank. So, after about a week in this tank he's got his color back and is actually fairly easy to find.
I also added 450 astrea (sp?) to the main tank, 50 astrea to the frag tank, 100 cerith, 100 nerites, and 2 fighting conchs. The snails are actually cleaning up all the hair algae. It's been almost 2 weeks since I put them in and I don't really even need to clean the glass. The snails also started to lay batches of eggs everywhere too. I guess they figure they've got enough food for babies.
I also picked up a Lobophylia and when I put it in the tank it started to spawn. Seriously, there were eggs spewing out of one of the lobes, and it lasted for around 15 minutes.
