that doesn't tell me much....many anemones look like that....you need to know the name to properly accomodate it. You should never buy anything that you don't know what it is. give us a pic at least maybe we can tell what they are. Anemones gain most of their sustanence from light and filtering food around them and if you DO feed them they eat fish. such as a piece of silversides every week or so.....most die from over feeding and not enough light making them expel their zoanthelle and then surely dying by starving to death. Not a nice prognosis for an elegant animal.
