Devils Hand Leather Coral Care Guide: Lobophytum Pruning

Beginners often pick the devils hand leather as their first soft coral because it survives the rookie mistakes that kill SPS within days. Lobophytum sp. tolerates wide nutrient swings, lower light, and the kind of stop-start dosing schedules that come with a busy first reef. This guide from Gensou Aquascaping at 5 Everton Park covers placement, the weekly wax-shedding cycle, and how to prune a runaway specimen back to a tidy lobed shape before it overruns the aquascape.

Recognising Lobophytum

The genus name describes the lobed digit-like growth — three to seven thick fingers radiating from a flat foot. Compare it to the smoother dome of Sarcophyton (toadstool) or the branched Sinularia finger leather. Colours are usually muted: olive green, mustard yellow, pale tan or grey-brown. Pure neon-green Lobophytum exists but commands SGD 90-150 per medium frag in Singapore reef shops.

Lighting Tier

Sit them in the low-to-medium PAR band, 100-200 µmol. Higher intensity does not increase growth meaningfully and instead bleaches the polyps that fringe each lobe. A Kessil A80 or single AI Prime HD covers a 60 cm cube comfortably. Position the coral on a mid-height shelf with the flat foot anchored to flat rockwork — the lobes need vertical room to extend at full polyp without bumping against neighbours.

Flow Requirements

Devils hand leathers want moderate, alternating flow. A Maxspect Gyre XF230 on the lowest random setting or a pair of Tunze 6055 powerheads creates the sway pattern they evolved with. Stagnant flow encourages cyanobacterial film on the lobes and causes the coral to retract permanently. Find compact options across the aquarium equipment range.

The Wax Shedding Cycle

Every two to four weeks the leather coats itself in a clear mucus-wax film, retracts the polyps fully, and looks effectively dead for two to three days. This is normal cleansing behaviour — the wax sheds bacteria and algae that have settled on the leathery surface. Boost flow during shedding so the wax peels away cleanly rather than collecting in the sump intakes. Skim it off with a turkey baster if it folds back over the coral.

Pruning Technique

Lobophytum will outgrow a 200-litre tank within 18 months if left unchecked. Pruning is straightforward: wait for the coral to retract fully, then cut a finger lobe off at the base with a sharp blade. Glue the cut frag to a plug using cyanoacrylate gel and stick it on a frag rack in lower flow until the foot heals over. The mother colony seals the wound within a fortnight and continues growing.

Toxin Release and Carbon

All leather corals release terpene toxins to suppress neighbouring corals. In a closed nano reef this can stunt SPS, zoanthids and acans. Run carbon continuously and change it monthly. Skip dosing GFO and carbon at the same time — stagger them by a week. The water care range covers reef-grade activated carbon.

Water Parameters

Salinity 1.024-1.026, alkalinity 7-9 dKH, calcium 400-440 ppm, magnesium 1300-1400 ppm, nitrate 5-25 ppm, phosphate 0.03-0.15 ppm. Lobophytum genuinely tolerates higher nutrients than SPS — a slightly dirty tank often shows fuller polyp extension than an ultra-clean one. Singapore reefers running natural seawater changes through Iwarna’s seawater service report stronger growth than RODI-only tanks.

Placement Distance from Other Corals

Allow 10-15 cm clearance from any LPS or SPS neighbour. The leather does not have stinging sweepers, but the chemical warfare reaches far through the water column. Pair with other soft corals — Kenya tree, Sarcophyton, Sinularia — that share the same toxin tolerance. Avoid placing torches, hammers and acans downstream.

Sourcing in Singapore

Common Lobophytum frags appear in Aquamarin, Iwarna and Reef Discus Centre rotation at SGD 35-65. Higher-end neon green and metallic gold morphs run SGD 100-180. Look for healthy specimens with extended polyps at the time of purchase — a fully waxed specimen could just be mid-shed but could equally be dying, so ask the shop how long it has held the piece. Gensou stocks soft coral starter kits, frag plugs and reef-safe glue across the marine and saltwater range.
