i have had over 20 anemones all my life so far, and until now the longest i have ever kept one alive was for a week, they always died, never found out why
i have been able to keep every kind of coral i had alive so far with no trouble, but anemones... are evil they shrink and die. there not my thing but i still love them. and i never got them to eat. they always threw up there food.
i fed mine shrimp and silversides
