nivram- there are many corals out there called Superman. The origianl named one came from Tubs (John Susbilla) and this is the Tyree LE piece. This coral, (which I believe is a M. tuberculosa, by the way...) is very easy to keep, stays colored up, and grows well. There are MANY wild and aquacultured corals out there that look the same. many of these are fairly easy to keep also, but some will brown out and take a long time, if ever, to color back up.
This is VERY tru.. MANY people will slap the name superman on it just because it is blue base with red polyps... Be careful who you get it from.. Ive had a few supermans that were wild that only browned out later.. You will always get good results with Tyree stuff but thats if you wanna pay $$$$ just for the name.. Its like Ed Hardy but for corals.. LOL.. You can find a nice superman for cheap just look around on here especially and try frags.org.. Hope this helps.. U will probly pay around $80 for 1/2 to 1" frag for tyree ballpark..
