They are a great beginner coral, a little more interesting than most regular shrooms
Any "softie" coral will work in a tank set up for these with a few exceptions so i would say get lighting for these, maybe on the bright side. Then the path will be open for leathers, shrooms
, zoas/palys and some LPS
like trumpet coral, duncans, torch, hammer etc
As previously stated these are easy to care for so you can get you feet wet(pardon the pun) before buying more expensive pieces.
