Since 1983 to present,(off and on), I've tried to keep alive and happy the corals under species Scleronephthya and Dendronephthya . And other similar type corals(softies ). Information in the past was limited. Until now. It maybe possible to keep and culture these bueatiful creatures. I don't know about you, but I like a good challenge. Always think outside the box. I have a DT, for nps corals, 30 gallons, 90 gallon refugium, outside, plumb to DT. Chiller, (gets hot here in summer ), 3 sulfur denitrators, dosing equipment, no apex, all old school. Some test equipment, ph, orp, chemical regiments. See my diy tide control thread, to get an Idea, of set up. I obtained 12 nps softies. Carnation corals, orange flower coral, etc... See short videos at YouTube under: So you want to raise Dendronephthya and Scleronephthya There hanging upside down or sideways. Sizes range 1/2" to 6". Three wavemakers, on one timer. I blend Chaetomorpha, strain add water, dose all day long on timer. The photo taken was on 3/1/18. Had this specimen since 1/15/18. Will post more photos soon, need to get better acquainted with camera features. They don't mind nitrates 20+, I've found out. The Dendronephthya are hardy. Possibly found in Victoria Harbour, Hong Kong. Very high in good and bad nutrients in harbor.
