They are the forgotten and the the hardest to care for Corallimorpharians. They are Ricordia yumas. These mushrooms are incredible in coloration and in color varience. I personally own at least 6 different morphs. If you start looking for one, you may come across this crazy specimen:
Luckily for you SPS owners, unlike the regular mushrooms, these do not multiply at a rapid rate. They make an excellent choice for a SPS dominant tank.


simply amazing!! I wish I had one! I wouldn’t mind these guys spread rapidly..
By the way, does anyone have tips to remove regular mushrooms?
Tempermental… but definately worth the effort. Hope to have one like the one shown someday!
As for the reg. ‘Shrooms… can the rock be worked on out of the main tank? If so, you’ll find the work much easier and will not produce chem warfare in your system.
I have had sucesss removing them just using my thumb-nail – worked with patience at the base of the offending mushroom. (The more agressive you are, the more toxin it will produce in your system.) This usually yeilds a healthy specimen that can be donated to another hobbiest or your LFS. After, take a stainless steel dental pick (usually found at a hobby shop) and scrape down the LRock where the mushroom base was attached. It will leave a blemish on the rock… but that will cover over with coraline soon enough. The key is to use stainless steel, this is inert in salt water. If the mushroom is not reachable with your thumbnail, Use the dental pick instead. Hope this method works for you, Good Luck!

Thanks Richard.
I find R. yumas to be slower growing and less of a nuisance than say the regular Discosoma mushrooms. Yumas tend to be more demanding and thus require a lot more care. Plus they are finicky once intruduced into your system.
