ive aquired quite a few of what i think are orange ball anemone (Pseudocorynactis caribbeorum) on some live rock and cant seem to find any information on how to keep them alive.. i know they can sting corals so they are set up right now in a 2 1/2 gallon with some live rock and feather dusters.. does anyone have any information concerning how to keep them happy? temp, salinity, etc.. i have been feeding them plankton and they seem to like that...
