These are African Blues or Blue Hornets, or Deep Water Blues there are so many different type of names for these but, I haven't have the slightest clue. But anyhow they do well under temperatures between 75-78 degrees anything above that they can start to melt on you. I made a mistake a few weeks agao when it all of a sudden got hot over here and my temps went up to 82 degrees they were closed up and were not happy I actually had to put an Ice pack in my Tank to get it to cool the temperature down a little. but once the temps got back down they opened up right away.
I just want to say I don't have all the facts on these because there are a lot of other reefers out there that are not having the best of luck with them. I know a lot of Folks are keeping these under High Lighting and some are slighting shading them. Also I would keep them between medium to high flow. Since these seem to be happy with the current and flow.
I also believe if you move them around every few days just to get an idea what spots make them open up and which spots don't. That's pretty much all the info I have right now on the these blue zoa's.. HTH
