Paraglab Torch Care Guide

Paraglab Torch (Euphyllia paraglabrescens) is a LPS coral. Care covers 75-175 PAR, medium flow, reef parameters and feeding; advanced level.

Overview

Paraglab Torch (Euphyllia paraglabrescens) is a LPS coral in the family Euphylliidae. Wall-growing torch relative with shorter tentacles and a thick fleshy skeleton. Produces designer-grade Japanese specimens.

Taxonomy

Family: Euphylliidae
Genus: Euphyllia
Scientific name: Euphyllia paraglabrescens
Common synonyms: Paraglab, Walling Torch

Habitat

In the wild, Euphyllia paraglabrescens is reported from Japan, Indo-Pacific, where it occupies mid to lower reef slopes and lagoons (typically 5-30 m). The species adopts a massive growth form on hard substrate within zooxanthellate reef communities.

Tank requirements

Salinity (specific gravity): 1.024-1.026
Temperature: 24-26 °C (75-79 °F)
pH: 8.1-8.4
Carbonate hardness (dKH): 8-11
Calcium: 400-450 ppm
Magnesium: 1280-1350 ppm
Phosphate (max): 0.03 ppm
Nitrate (max): 5 ppm
Minimum system age: 6 months

Placement and lighting

PAR (placement zone): 75-175 PAR
Water flow: medium

Mount this LPS coral on the lower or mid rockwork or on the sand bed (for free-living forms) where light is moderate. Strong direct flow can damage the fleshy tissue; aim for indirect, varied movement.

Feeding

Euphyllia paraglabrescens hosts symbiotic zooxanthellae and derives most of its energy through photosynthesis. Supplemental target feeding accelerates growth and supports colouration; commonly accepted items include mysis, reef-roids, amino-acids. Feed once or twice per week after lights-out, when polyps are extended.

Compatibility

This coral is aggressive toward neighbours. It extends sweeper tentacles capable of stinging adjacent corals, so leave generous spacing (10-20 cm) between colonies. Reef-safe with most fish and invertebrates.

Care notes

Difficulty level: advanced. Reported skeletal growth in well-tuned reef tanks is approximately 0.1-0.3 cm/month. Propagation by fragmentation is straightforward for massive colonies — separate branches or polyps with a bone cutter, glue to plug, allow 1-2 weeks for healing. Maintain stable alkalinity (avoid swings above ±0.5 dKH per day) to preserve tissue health.
