Picked up a piece of these, originally came from roesmarineworld.com, cant find any info on this coral. Can anybody give me some info! They were doing well on the sand bed of a 2ft deep tank almost directlly under 250w 20k MH, i placed then about 12in down under 175w 15k MH. I searched the net and found nothing. Any info is appreciated.

Hey Joe,

Is that the correct spelling?

joefish · Dec 24, 2008

That is the spelling from roesmarineworld.com, here is a pic. Small green fingers, tanish face with pale yellow mouth.

Hey Joe

I don't think that is a correct name.....I looked in all my books and on-line and can't even find a coral with that name.....I will keep looking....That is definitely a sweet piece..

Try this spelling: Rhizangiidae

are you talking about the Super UBER expensive "Rhizo" ?

Last sunday at the swap i was told there is info on these in "corals of the world" by J.E.N. Vernon. A $160 book set isnt in my budget, if someone who has these books could look them up give some info it would be appreciated.

Hey Joe,

Don't have the book but how is that frag doing of that coral? How you been?

joefish · Jan 29, 2009

Hey Az, ive been fine. The frag got knocked off the shelf and landed polpys down on top of a shroom and is looking a little rough but I think it will be fine, may have lost a head or two will have to wait and see.

If your talking about the photo on the right, second up, I'd be worried about that black sponge on that rock...it could choke out your coral. I'd take it out of the water for a couple of minutes to expose it to air, squish out some of the water with a gloved finger and then using a pair of tweezers, peel off as much as possible. At least that's what it looks like from this angle...can you get a closer / clearer picture?

The family is Rhizangiidae. There is only one genus/species listed-Astrangia poculata. Sounds like a range of descriptions, though. Colonies are encrusting, submassive, or branching, can be zooxanthellate or azooxanthellate. The areas shown in Corals of the World are right along the Gulf Coast (Ms, AL, Tx, La, etc.), up the east coast of the US, and another light, gridded area (Eastern US is solid color) along the north west coast of Africa. Apparently, other names are A. danae and A. astreoformis, though CotW only lists A. poculata as official.

BTW, some of the pictures look a lot like the Caribbean Cup Corals that several have asked about lately, though the pictures vary as much as the description.
