sorry i don't have a pic - but a question that has likely been answered many times but seeing that this thread is nearly 4 years old maybe there are some new insights
obviously challice corals include at least 3 genera of Pectiniidae (oxypora, echinophyllia, and mycedium) as well as the Faviidae genera echinopora and others maybe???
and because of the small size of most of the LE or otherwise named ones it is very difficult to ID them but i'm wondering has anyone discovered any important differences in care requirements for the different genera or are most/all challices similar in their care making it not really important?
