found this on a different site. these things look pretty cool. never heard of one before. Looks like this guy has had luck with them with wrasse and tangs. no angels or triggers.
they are carnivores so i would assume (don't know for sure) that they would be reef safe. probbaly really hard to get to eat frozen as they wait till stuff passes by to eat.
Seagoblins, a man after my heart. These are really cool scorpionfish that spend 90% of th eday bruied under the substrate w/ their eye poking up. They are ambush feeders that wait for food to pass overhead then they spring out of the substrate to engulf its prey, then climb back under.
There are 3 species of this fish that are common in the hobby, one pretty and 2 ugly--okay all are ugly, but ones colorful and they others aren't) Inimicus caledonicus and Inimicus didactylus tend to be dull are frequently solid grey or grey/tan/black, but occasional colorful specimans exist and I. filimentosus frequently is covered w/ blotches of colored looking skin mimicing sponge.Their heads look very different is usually the best way to ID these fish.BTW their common names are seagoblins or ghouls.
AS for care and compatibility. They require docicle tankmates, and access to live food at first. Like Keith mentions they will eat anything that fits into their mouths, and in my experience require live ghost shrimp or sw feeders to get established in your tank. Additionally, any tankmate that picks on their skin (like angelfish or triggers) my have to be seperated. I found these fish very neat and hardy w/ my other scoprionfish, tangs, wrasses.
Lastly, becuase they do hide under the substrate frequently, please excerise care when you clean the tank, make sure you can see the fish just to keep from getting a surprise and they are of course venomous-like all scorpionfish
I've attached a link to a whole issue of reefkeeping mag on keeping scorpionfish, beside the great article on keeping lionfish, there is one on keeping scorpionfish, inwhich photos of my imicus are there
