Very true ... there was an article about them on Reef Builders I seem to remember but other than that there is not much available ...
I've used that and some basic knowledge of the only other species in the genus, the arrowhead soap fish to get an idea what kind of animal this guy is. He is a predator, though a small one. He eats whatever he can gobble up. They do not like light and they cannot live in a standard reef tank's "hot" climate. They do fine at low pressure as long as they are safely brought up from the deep. An ideal habitat would be mostly actinic since at that depth everything is blue until you turn on a white light and see the tremendous color and housed with larger fish that won't eat them. Though this information is not completely important until the fish becomes more affordable and people actually need to know about their care. Deep water enthusiasts all over the world are all drooling about all these awesome guys, at least I am haha! It is amazing how little we have seen in the ocean. I hope that I get to witness the final animal discovery in my lifetime. Then all those marine biologists can take a vacation from...oh wait, they play in the ocean all day, they do not need a vacation at all!
