Lighting
100-180 PAR is a starting range; fleshy tissue should expand without paling, stretching, or pulling against skeleton.

Ranges
These ranges are approximate starting points from the coral database and should be adjusted to the stability and history of your system.
Care
100-180 PAR is a starting range; fleshy tissue should expand without paling, stretching, or pulling against skeleton.
moderate indirect flow should move tissue gently without folding it into sharp skeleton or neighbors.
For Torch Coral, verify salinity and alkalinity trends before changing placement; repeated moves and direct corrective swings can irritate fleshy tissue.
Torch Coral requirements vary by specimen, aquaculture history, shipping stress, and tank maturity; use these ranges as starting points, not guarantees.
Feeding
ID
Torch coral usually has longer, less-branched tentacles than hammer or frogspawn coral. Torch Coral is best separated from Hammer Coral and Frogspawn Coral by weighing long single tentacles, rounded or contrasting tips, and branching or wall skeleton. Look at corallite walls, polyp shape, tissue inflation, and where recession begins; then compare that structure with where the coral expands, retracts, or shows early recession. Do not rely only on color under blue lighting. Because trade photos can exaggerate color, skeleton shape, polyp layout, and expansion pattern are stronger clues than color alone.
Placement
Compatibility depends on specimen size, flow, growth, aggression, and spacing. Use these references conservatively and watch for contact over time.
Spacing recommendation: keep about 6 inches of clearance, then adjust based on extension and neighboring coral response.
Troubleshooting
Use these as troubleshooting checks, not a diagnosis. Symptoms may point to more than one issue.

FAQs
Torch Coral is better treated as intermediate because placement, flow, feeding response, or aggression can vary by specimen.
Start Torch Coral in the middle third with room to adjust up or down. Use 100-180 PAR and moderate flow as a starting point, then adjust from tissue extension, color, and nearby coral response.
Torch Coral may benefit from careful target feeding with mysis, small meaty foods, and LPS pellets. Use the listed frequency as a starting point: 1-2 times weekly if the coral accepts food. Feed only when the coral accepts food and avoid forcing food into stressed tissue.
Give Torch Coral about 6 inches of clearance as a starting point. Its database aggression level is High. Use caution near Hammer Coral, Frogspawn Coral, and Goniopora. Avoid close placement with Acropora, Montipora Capricornis, and Zoanthids. Compatibility is not a guarantee, so check contact points as colonies expand.
Use this as a troubleshooting check. For Torch Coral, long tentacles touching nearby corals after lights out and Torch Coral shows less normal extension, inflation, or feeding response than its recent baseline can indicate Torch Coral sweeper contact or base recession. Likely causes to check include direct laminar flow, tight spacing, or an alkalinity swing irritating the base and recent placement, lighting, flow, or chemistry changes affecting Torch Coral. Start with these database checks: check Torch Coral alkalinity trend and look for nearby stinging contact and reduce direct flow if tissue is pressed against skeleton.
For Torch Coral, verify salinity and alkalinity trends before changing placement; repeated moves and direct corrective swings can irritate fleshy tissue. The database lists 6 months as the minimum tank age and 30 gallons as the minimum tank size. For LPS-style care, protect fleshy tissue from repeated moves, direct flow, and abrupt chemistry corrections.
