Pseudocorynactis spp.
A corallimorph whose tentacles end in bright orange or white balls. It opens its disc at night and catches prey with those ball tips. It builds no skeleton.
Pseudocorynactis is a corallimorph genus in the family Corallimorphidae, erected by den Hartog in 1980. Related to the stony corals, it builds no calcareous skeleton. Its tentacles end in swollen balls that glow bright orange or white, which is why it is traded as the orange ball anemone. By day it contracts into rock crevices and under overhangs; at night it spreads its disc and tentacles to catch zooplankton and small crustaceans, and it is known for swallowing prey large relative to its own size. WoRMS currently recognises only two valid species, P. caribbeorum and P. tuberculata; the former P. globulifera and P. caboverdensis have been moved to Corynactis and P. hoplites to Paracorynactis, so the trade name alone does not identify the species. Having no skeleton, it is not covered by the CITES coral listings.

It is nocturnal and contracted by day, so it needs no strong light. Site it in shade, under an overhang or in a crevice.
Place it in a crevice or shaded spot in gentle flow; the tentacles will not open in strong current. Choose a spot you can reach for target feeding.
Water 24-26C, specific gravity 1.023-1.025 (salinity 33-35 ppt), pH 8.1-8.4, KH 8-12. Because it is fed heavily, watch for rising nutrient levels.
After lights-out, when the tentacles have opened, offer chopped seafood or brine shrimp with tweezers. AlgaeBarn recommends a varied diet including larger zooplankton for predatory corallimorphs of this kind.
It is an effective predator and can take small shrimps or fish that touch its tentacles, so choose tank mates with care. Having no skeleton, it is not covered by the CITES coral listings.
Intermediate. This is an intermediate-level species. Some prior experience and knowledge of environmental management are recommended.
The ideal temperature for Orange Ball Anemone (Pseudocorynactis) is 24〜26℃. Avoid sudden temperature changes and maintain a stable environment.
