Yumas are from the Pacific and a deep water ricordia that IMO should not be removed from the water and does not stand nitrates. Both can cause them to melt. Also not acclimating them to lighting and high flow will cause them to melt and sometimes just because, will cause them to melt.
Once they are established you can cut them up and grow them out, but they are pretty good about dropping babies, much like a common mushroom, so cutting them really is not needed.
Ricordia FL are from the Caribbean are pretty much indestructable. You can mash them, cut them, leave them out of the water for up to 1/2 hour and longer and they will be fine. Halving a FL ricordia and even quartering one will result in double, quadruple your stock in a weeks time. They heal fast. But there again, they don't like high nitrates. They do like high lighting. I have never in all the time I have kept FL ricordias, killed one. I have cut them, accidently crushed them, left them out on the frag plate and forgotten about them, just bought them from places that have kept them under low PC lighting and placed them directly under MH and they have done fine.
I worry about my yumas all the time checking on each one daily, my FL ricordias I don't even think about except to notice when they are getting too large and covering some other coral. I don't worry if they cover each other, they can and will move.
I have found that yumas touching other yumas, and even touching FL ricordias have a better survival rate than single polyps off by themselves. That is unless they are of the same rock from the start and begin melting, 9 times out of 10 it was in the collection/shipping process that initiated thier oncoming demise and not much you can do about it.
I only buy yumas locally that have been in the LRS for at least a week or from people I know to have grown them out themselves.

Is it bad if I only light acclimated for like 20 minutes? Because the little white baby yuma (supposed to be one at least) in my tank I have under much dimmer lighting then what it is was under in the LFS and I didn't light acclimate for very long. I am kinda worried because it is still only a greenish white and it hasn't gotten any bigger than what it was in the LFS, while the red common shroom I got has nearly tripled in size and is getting ready to split (obviously a big difference in hardiness and growth but just in case).
