Depending on the specimen and lighting, it may show shades of neon green, lime, mint, emerald, teal-green, yellow-green, olive, or deep forest green across the tentacles, tips, mouths, and tissue. This coral is best treated as a Torch Coral, commonly associated with Euphyllia glabrescens or closely related torch-type euphyllid corals. It grows as individual fleshy polyps on a branching or wall-like skeleton, depending on the specimen type. Most aquarium specimens are sold by head count. Green Tip Green Torch Coral is popular because it adds dramatic movement, bright color, and classic Euphyllia shape to reef aquariums. Its long waving tentacles create the flowing look reef keepers love, mostly because apparently we enjoy keeping beautiful animals that can also sting their neighbors at night like tiny fluorescent villains. This coral is photosynthetic and receives much of its energy from reef lighting through symbiotic zooxanthellae. It may also benefit from occasional feeding with small meaty foods, especially when tentacles are extended and feeding response is visible. Green Tip Green Torch Coral is considered aggressive. It can extend sweeper tentacles, sting nearby corals, and damage tissue on neighboring LPS, SPS, soft corals, zoanthids, mushrooms, and anemones. Give it space. Do not wedge it into a coral garden and act surprised when the reef turns into a glowing fistfight. Note: Image is a representation of what to expect. The coral you receive may vary slightly in size, head count, tentacle length, green intensity, tip color, mouth color, skeleton shape, extension, and overall appearance. AQUARIUM REQUIREMENTS AQUARIUM SIZE A minimum aquarium size of 20 gallons or larger is recommended for Green Tip Green Torch Coral, though larger mature reef systems are preferred. Larger aquariums provide better stability, more placement options, and more room for spacing from nearby corals. Torch corals can be kept in nano reefs by experienced keepers, but small tanks make aggression and parameter stability harder to manage. A single torch head can extend much farther than expected, and nearby corals do not care that the tank is “only temporary.” They just get stung anyway. PLACEMENT RECOMMENDATIONS Green Tip Green Torch Coral is best placed on lower to middle rockwork where it receives moderate indirect flow and low to moderate lighting. Lower Placement: Best for new arrivals, stronger lighting systems, or fresh frags. Middle Placement: Works well once the coral is settled and showing good extension. Rockwork: Place on stable rockwork where the skeleton is secure. Sandbed: Can work in some systems if the coral is mounted securely and not being buried by sand. Avoid High Light Immediately: Start lower and move gradually if needed. Spacing: Leave several inches between this torch and neighboring corals. Sweeper Tentacle Room: Give extra space down-current because tentacles can reach farther with flow. Avoid Direct Contact: Do not allow it to touch other corals. Stable Mounting: Make sure the frag plug or skeleton is secure and cannot fall onto another coral. Do not place it directly beside hammers, frogspawn, torches from unknown systems, or expensive LPS colonies and call it “cozy.” That is not cozy. That is coral litigation with calcium skeletons. WATER PARAMETERS Green Tip Green Torch Coral does best in clean, stable reef water with moderate nutrients. Torch corals are less forgiving of parameter swings than many soft corals and can react poorly to instability, shipping stress, low nutrients, bacterial issues, or rough flow. Temperature: 75-79°FpH Level: 8.1-8.4Salinity: 1.024-1.026 specific gravityAlkalinity: 8-10 dKHCalcium: 400-450 ppmMagnesium: 1250-1350 ppmNitrate: 5-15 ppmPhosphate: 0.03-0.10 ppm Avoid major alkalinity swings. Rapid changes can cause tissue stress, retraction, poor extension, or tissue recession. Torch corals often do better with some measurable nitrate and phosphate rather than ultra-low nutrient water. The goal is stable reef water, not sterile glowing sadness under blue LEDs. LIGHTING Green Tip Green Torch Coral prefers low to moderate reef lighting. It can adapt to a range of lighting, but sudden high light can cause stress, retraction, bleaching, or reduced extension. LIGHTING RECOMMENDATIONS Starting PAR: Start around 50-100 PAR when newly added. Target PAR: Many torch corals do well around 75-150 PAR. Upper Range: Some specimens may adapt to around 150-200 PAR, but increases should be slow and careful. Avoid Sudden High Light: Strong lighting too quickly can bleach or irritate the coral. Gradual Acclimation: Increase intensity over several days to weeks if moving upward. Color Display: Green coloration and green tips often show best under blue-heavy reef lighting. Too Much Light: Signs may include bleaching, pale tissue, short tentacles, retraction, or tissue recession. Too Little Light: Signs may include dull color, weak extension, slow growth, or stretching toward light. Do not blast a fresh torch with SPS-level lighting because it looked bright in a vendor photo. That is not coral care. That is photon bullying with a payment receipt. WATER FLOW Green Tip Green Torch Coral prefers moderate, indirect, random flow. Flow is one of the most important parts of torch coral care. FLOW RECOMMENDATIONS Ideal Flow: Moderate, indirect, alternating, or random flow. Avoid Direct Blast: Do not aim a powerhead directly at the coral. Tentacle Movement: Tentacles should sway and lift naturally, not whip violently or stay pinned to one side. Avoid Dead Spots: Low flow can allow detritus to collect around the skeleton and tissue. Protect Tissue: Excessive flow can cause tentacles to rub against the skeleton and become damaged. Feeding Flow: Flow should allow the coral to hold food if target feeding. Down-Current Spacing: Leave extra room in the direction the tentacles move. A torch coral should look like it is gently waving, not surviving a hurricane documentary. If the tentacles are thrashing into the skeleton, the flow is not “high energy.” It is rude. DIET Green Tip Green Torch Coral is photosynthetic but can benefit from occasional feeding. PRIMARY DIET Photosynthesis: Reef lighting provides much of the coral’s energy. Mysis Shrimp: Excellent meaty food when appropriately sized. Brine Shrimp: Useful variety, especially enriched. Calanus: Good smaller planktonic food. Finely Chopped Shrimp: Use very small pieces. Finely Chopped Clam: Good meaty option if chopped small. LPS Pellets: Small coral pellets may be accepted. Powdered Coral Foods: Can be used lightly as part of broadcast feeding. Amino Acids / Reef Nutrition Products: Optional, but may improve feeding response and tissue fullness in some systems. Fish Feeding Benefit: Normal fish feeding often provides dissolved and suspended nutrition. FEEDING FREQUENCY Feed lightly 1 time per week if desired. Some systems do well with occasional feeding every 1-2 weeks, while others may benefit from small weekly feedings. Feed only small pieces. Large chunks can be rejected, rot, or irritate the coral. A torch coral is not a meat locker with tentacles. Humanity keeps needing reminders. Turn down flow briefly during target feeding if needed, then restore flow after the coral has captured food. COMPATIBILITY Green Tip Green Torch Coral works well in mixed reefs when given space, stable conditions, and careful placement. COMMON TANK MATES Fish: Reef-safe fish such as clownfish, gobies, blennies, wrasses, tangs, rabbitfish, cardinalfish, anthias, and other peaceful to semi-peaceful fish. Use Caution: Angelfish, butterflyfish, filefish, puffers, and other fish known to nip LPS corals. Invertebrates: Generally safe with cleaner shrimp, snails, hermit crabs, and common reef invertebrates, though some shrimp may steal food. Coral: Compatible with many soft corals, zoanthids, mushrooms, LPS, and SPS if spacing is managed. Avoid Direct Contact: Do not allow it to touch neighboring corals. Torch-to-Torch Contact: Torches may sometimes tolerate nearby torches from compatible systems, but mixing different torch strains still carries risk. Euphyllia Contact: Do not assume torches can safely touch hammers or frogspawn. Torch corals are often more aggressive and may damage other Euphyllia-type corals.

A torch coral placed too close to other corals is not “maximizing space.” It is writing a tiny green eviction notice with nematocysts. BEHAVIORAL NOTES Temperament: Aggressive. Growth Pattern: Usually branching in the aquarium trade, though wall forms exist and are generally more difficult. Tentacle Extension: Healthy torches extend long fleshy tentacles that move with flow. Green Tip Appearance: Green tips may appear brighter under blue-heavy lighting. Green Body Color: Tentacles may show neon green, lime, mint, emerald, teal-green, olive, or yellow-green depending on lighting and specimen. Sweeper Tentacles: May extend longer tentacles, especially at night or when irritated by nearby corals. Retraction: Temporary retraction can happen during acclimation, lights-off periods, feeding, handling, or irritation. Tissue Health: Tissue should remain inflated and cover the skeleton edge when healthy. Skeleton Edge: Sharp skeleton edges can damage flesh if flow is too strong or the coral is handled roughly. Brown Jelly Risk: Euphyllia-type corals can be vulnerable to rapid tissue loss and brown jelly-like infections, especially after damage or stress. Head Splitting: Healthy branching torches may slowly split heads and grow new branches. Frag Sensitivity: Fresh-cut torch frags may take time to settle and should be monitored closely. Pest Awareness: Inspect for flatworms, nudibranchs, vermetid snails, algae, aiptasia, and tissue damage. Handling: Handle by the skeleton or plug. Avoid touching the fleshy polyp. Shipping Stress: New torches may stay partially retracted for a few days. Trade Name Reality: Green Tip Green Torch Coral is a trade-name color description, not a guaranteed scientific species identification. Color intensity, tip brightness, tentacle length, and growth rate vary by specimen. Placement Reality: Give it moderate light, random indirect flow, measurable nutrients, stable alkalinity, and room to sting the empty water instead of your other corals. This is not complicated, which naturally means someone will still put it next to a chalice. HEALTH AND COMMON ISSUES Green Tip Green Torch Coral is beautiful but can decline quickly if stressed, damaged, or kept in unstable conditions. COMMON HEALTH CONCERNS Tissue Recession: Can be caused by instability, damage, poor flow, pests, infection, or low nutrients. Brown Jelly Disease: A fast-moving tissue-loss condition that can affect Euphyllia-type corals. Bleaching: Usually related to excessive light, rapid light changes, stress, or poor conditions. Skeleton Damage: Rough handling can damage tissue around the skeleton. Flow Damage: Strong direct flow can cause tissue to rub against the skeleton. Low Nutrients: Ultra-low nitrate and phosphate may lead to pale tissue or poor extension. Alkalinity Swings: Rapid changes can trigger stress or recession. Pests: Inspect for flatworms, nudibranchs, vermetids, aiptasia, and other irritants. Neighbor Stings: Damage can occur from nearby aggressive corals. Food Theft: Shrimp and fish may steal food and irritate the coral. WHEN TO TAKE ACTION Take action if the coral shows exposed skeleton, rapid tissue loss, brown jelly-like slime, foul odor, severe retraction for multiple days, melting tissue, or sudden loss of multiple heads. Early correction matters. Waiting to see if a torch coral “figures it out” is how reef keepers convert premium LPS into a decorative calcium fork. ACCLIMATION PROCESS This acclimation method helps reduce stress by gradually introducing the coral to your aquarium’s temperature, lighting, and water chemistry. 1. DIM THE LIGHTS Turn down aquarium lights or place the coral in a shaded lower area at first. This helps reduce stress while it adjusts. 2. FLOAT THE BAG Float the sealed bag in the aquarium for 15-20 minutes to allow the temperature in the bag to equalize with the tank. 3. OPEN BAG, ADD CORAL TO CONTAINER Carefully open the bag and transfer the coral and shipping water into a clean container. Handle the coral by the plug or skeleton, not the fleshy tentacles. 4. ACCLIMATE USING TANK WATER Add small amounts of tank water to the container every few minutes for 20-30 minutes, especially if salinity differs between the shipping water and aquarium. 5. CORAL DIP Use a coral-safe dip according to the product instructions. Inspect carefully for pests, eggs, algae, aiptasia, vermetid snails, tissue damage, recession, brown jelly, and exposed skeleton. 6. TRANSFER CORAL TO AQUARIUM Place the coral on lower-to-middle rockwork with low to moderate light and moderate indirect flow. Discard shipping and dip water. Do not pour either into your aquarium. 7. LIGHT ACCLIMATE Start in lower light and gradually increase exposure over several days to weeks if needed. 8. ADJUST FLOW CAREFULLY Make sure tentacles sway naturally without being blasted or pushed into the skeleton. 9. GIVE SPACE Leave several inches of space between the Green Tip Green Torch Coral and nearby corals. Watch nighttime extension and down-current reach. 10. WAIT BEFORE FEEDING Allow the coral to settle before target feeding. Once extended consistently, offer very small meaty foods if desired. 11. MONITOR CLOSELY Watch for retraction, bleaching, exposed skeleton, tissue recession, brown jelly-like slime, poor extension, or damage from nearby corals. A torch coral can go from “gorgeous centerpiece” to “expensive green regret” with insulting speed. Show more
