Yes, I have him near the at the top of the reef near the lights.
I have been target feeding him a cyclopeeze/oyster egg combo one day and a couple days later I fed him some of my homemade squid and shrimp slurry. I have also been using Live phyto-feast twice weekly for my filter feeders. I am keeping my fingers crossed.
So the last couple of week when I take my flashlight to the dark tank I have seen a cirolanid isopod. I have seen him at least a half dozen times. When The light goes on him he drops into the substrate. Well last night I saw where he went. I grabbed the fishnet and put it near when he landed. eventhough I could not see him any longer I put the net on the sand and he swam away. But not fast enough, I netted the little bugger and he is no more!! I dont know if he is the only one but I have only seen one cirolanid swimming at a time.
I am seeing more and more beneficial pods of various sizes in the tank in bot the substrate and the rocks. I also have seen a tiny shimp of some kind. He is 1/4-3/8 of an inch long. I got two peppermint shrimp with the TBS Package. One of which disappeared the second I added her to the tank so I dont think she survived. The other peppermint I usually see every evening although I have not seen him for a few days. He could just have gone into hiding to molt. Or he was hanging out by the mantis and became a feast.
The tiny shrimp is pretty cool looking. I have tried to take pics but they are too blurry. I did take some this morning with the flash but I had to go to work so I have not seen them yet. Maybe there will be a descent pic. He has big eyes

on his tiny head and his tail section points upward
I have seen him on one of the ball sponges a couple of times so I am guessing he is eating phyto-feast or oyster eggs that is caught on the sponge.
