Currently cycling my new FOWLR tank with live rock and live sand. I was inspecting the tank yesterday while I was testing the water and something bright green dart into a hole in the live rock, I watched the spot for a few minutes and some very alien looking eyes appear at the entrance of the hole, thinking that it may be a mantis shrimp I put a piece of frozen krill on the end of a bamboo skewer and held it near the hole and sure enough a small green mantis shrimp darted out and took the bait! This changes my stocking plans all together as I would like to keep him, very cool. I know that the cleaner crew I planned on will be decimated by him in no time so I was thinking of some Chromis and Gobies, any thoughts on this?
