Diaseris Fragilis
Diaseris is actually a member of the Fungiade-Fungia genera. It is new to the retail part of the hobby, and perhaps because of this it is currently listed as seperate from the Fungia/Cyclerosis family. Less often one will see it's scientific name listed as Fungia Distorta.
Diaseris seem to fare best placed on substrate like it's Fungia cousins.
They require medium light, from Metal halide or T5.
They like medium flow.
You can feed it mysis, cyclopeeze, frozen foods and zooplankton (best done when the tentacles are out).
