jeeze steve, that colony is fantastic! if you ever have any that you would like to part with, you let me know!
out of ll teh corals ive seenmy seven years in this hobby, i still think that these little mushrooms have got to be the coolest thing in the world...my current mission is to get a true blue Ricordea florida liek in steves pic above...i currently have a colony of orange yumas similar to Bang Guy's, two greens that i bought as fuzz's (thanks to the poor knowledge of the lfs!), a pink/green/blue colony that is fantastic and is getting ready to divide, and a single bluish/orangish one that cost a fortune...it is my experience that these little guys do better in higher lit tanks, and benefit visibly from target feedings with meaty foods... i have also found that a lot of the florida species enjoy a good deal of water flow because they are very streamlined to the rocks that they are found on...but this is just my experience!
keep the pics coming!
good luck
jon
