First sighting of itĭue to the macro shot, and the fact that my tank is a standard 20-Gallon, and not made with Notice the baby Yuma at the bottom to the left (in Author’s Nano-Reef).

yuma will not expand and will certainly not open up. They are some of the easiest corals to maintain, as they are not particularly demanding on the water quality, although of course the water chemistry cannot be totally off from where it should be or the R. An image of such reproduction is shown below as it happened in the Author's 20-gallon Tank. They can grow up to 4 or more inches when fully expanded, and reproduce in a number of ways: dropping “babies” off the main Yuma, or by splitting a small portion of their foot (pedal disc) off, that eventually grows into a little Yuma and keeps growing to become a larger and larger one. yuma comes in many different colors: reddish, brown, blue, yellow and so on, as can be seen in the images below. Best is to refer to them as "Yumas", and everyone who has been around for a while will know exactly what you are talking about. I have seen so many different ones that it is sometimes hard to even associate the common name used with what the life form really is. Hence the many common names given to them that may include several names of species they do not really belong to.

Often referred to as "Yumas", these are not true corals and not true anemones either, but somewhere in between a mushroom and an anemone.
