yes the orange is a sun coral.
as for the shroom i really dont know. just a regular old shroom i guess. i liked because of the way i fades into the yellows at the tips. when i got it was fully green then it turned into this. one of my fav shrooms now. its about 3 inches.
here are some pics of my other fax shrooms/ricordia/ and a pic of my new nano i just set up a few weeks ago. just played around in it alot today so it really cloudy but here it is anyhow
