A Jason Fox signature Leptoseris, an encrusting and plating coral in the family Agariciidae that lays down thin overlapping plates over rock, with an orange body and bright green mouths scattered across it. The genus lives mostly in the mesophotic zone, from the shallows to past 100 metres, which is why a coral this vivid wants so little light. Grows steadily rather than fast, and in a home tank it encrusts first and plates out as it settles.
Orange, with green eyes, on a thin plate. Orange is a rare colour in corals and the green mouths against it are the whole identity: a Leptoseris that is orange without the green mouths is another lepto, and a green-eyed orange coral with thick, cupped plates and larger eyes is more likely a chalice (Echinophyllia) sold under the name. Under too much light it browns and the orange goes first, so a dull frag from a bright display may be the genuine article in the wrong spot rather than a fake.
Low light and gentle flow, where nothing can sweep it. Jack-O-Lantern is intermediate to keep at a typical PAR of 50–150 in low to moderate flow. A typical starting range for this type of coral rather than a measured requirement for this morph. Spectrum, how it was acclimated and the system it grew in all move it.
No verified sales yet. A range publishes once 3 dated, checkable records from 3 different sources exist, priced per frag and reported as a median, with what shops ask kept separate from what buyers paid. One frag is a single cut on a plug, whatever its exact size. Colonies, mini colonies and mother stock are excluded rather than averaged in. Nothing on this page is for sale.
