Just saw your post.
From what I have witnessed is these guys do better on there own unless you have a pair, good find by the way!! They perfer lower light, however I have one in a bright tank that has adapted very well. It took a while to get him to feed, but I feed Cyclop-eeze and Hikari Mysis shrimp, both frozen. He doesn't touch the cyclop, however he didn't start feeding on mysis until I mixed the two together. Keep your salinity, temp and pH especial stable and all other parameters in check and you should be fine as long as they are eating. I keep my tank at 1.025, 78-79, 8.1 - 8.3. Above anything else acclimate by drip and turn off lights for the first day.
