I think I know where your getting them from..........and all you'll have to worry about with those babies is acclimating to temperature! Other than than I might use some Revive.
If it is from CoralMorphologic there is no purpose to dip.....In fact there is very little if anything that will come in on Ricordea. Most rics come in on rock rubble or bits of rock where there is very little for anything to hide. There is only one thing I ave found that actually eats on Ricordea and from what I have seen an heard, read that there is very little chance of you getting anything that will cause issues with other corals.
