Overview

Torch coral (Euphyllia glabrescens, family Euphylliidae) is a large-polyped stony coral whose long, sweeping tentacles terminate in rounded tips resembling burning torches. Native to reef slopes of Fiji, Indonesia, and Australia, its tentacles come in green, tan, gold, and purple, with potent cnidocyte-tipped ends capable of stinging neighboring corals. In aquaria, moderate lighting (150–250 PAR) and gentle indirect flow allow the tentacles to sway gracefully; strong direct flow causes retraction. Stable alkalinity is critical, as sudden parameter shifts stress this species. Occasional target feeding with small meaty foods enhances health and coloration.

Natural Spawning and Breeding in LPS Corals | Key Points for Juvenile Coral Rearing and Parental Stock Selection

Natural spawning in LPS (Large Polyp Stony) corals is a biological event triggered by multiple interacting environmental factors. The primary driver is photoperiod: as day length extends from spring into early summer, gonadal development in individual colonies accelerates. Most LPS species reach their spawning season between April and July, with decreasing nighttime illumination and lunar cycles serving as the final spawning triggers...
