Selection: Do pay special attention during the initial inspection and quarantine phases of acclimating new specimens for the presence of predaceous pests. Small, cryptically colored Nudibranchs (e.g. the Aeolid, Phistella melanobrachia) and Wendletrap Snails are often accidentally imported with wild-collected specimens.
Acclimation: For Azooxanthellates species should include the application of juice and bits of meaty foods sprayed with a turkey baster in the colonies direction at night time (when their polyps are typically open), even if their tentacles aren't evident. Placement: Both photosynthetic and non-photosynthetic species can/should be placed in areas of good lighting... the latter to assure adequate water flow. Further, to prevent covering by detritus Dendrophylliids should not be placed on the bottom but anchored up and on rocky points to facilitate water flow around their colonies. Reproduction/Captive Propagation: Tubastrea has been reproduced by asexual budding, breaking as well as (sexual) planula release. Turbinaria are easily propagated by the breaking off of pieces from a well-adjusted, healthy colony. This genus has also been observed to release planula larvae in captivity. Foods/Feeding/Nutrition: Tubastrea need daily feedings to all polyps to stay healthy... a regular regimen of turning off filter pumps during these times (on timers best... so you don't forget to turn them back on) for fifteen minutes or so (with other, recirculating pumps running) is optimal. Photosynthetic Turbinaria can get by on foods manufactured by their endosymbiotic algae, but are better fed (small zooplanktonic items or mashes of larger items) a few times a month. Disease Without regular food offerings, Azooxanthellates species will not open... begin tissue recession, and eventually succumb to algal overgrowth. Cloze: The lack of success with this family is principally due to two factors, for the Azooxanthellates Tubastrea et al. genera, a lack of feeding (or provision for the consequences thereof), and for the photosynthetic Turbinaria, a general lack of "promotion"... they're easily kept, as long as maintained off the bottom and swept/blown clean of detritus and mucus.
