[coralite]

Cycloseris is the smaller, flatter disc coral which commonly comes in solid neon green and orange. It has smoother septa and usually a flatter underside. These are not nearly as hardy in regards to fragging and they are much less likely to develop stalked juveniles from the skeleton if it is damaged.

Fungia grows much larger and it does not occur in solid green or orange. Instead they are usually colored yellow, green or brown, often with a purple rim and or purple mouth. Fungia will commonly exhibit a purple color where it has suffered mechanical damage or if it stressed. So dont buy that purple fungia for its color because it may or may not stay that way. It has a much thicker disc with a more concave underside. The septa tend to be a lot more toothy also. Fungia takes well to fragging as long as part of the mouth is present and it is the species which commonly produces stalked juveniles if tissue is caused to recede from part of the skeleton.
