Why is my Banana Torch Coral losing its bright yellow and looking green or brown?

Color shifts usually track with light spectrum, PAR, and nutrients. Aim for moderate PAR (120–200) with strong blue spectrum; too white or too intense light can wash yellow. Keep nutrients detectable (NO3 5–15 ppm, PO4 0.03–0.1) and parameters steady. Avoid rapid changes. Trace balance matters—iodine and potassium within natural seawater ranges help, but don’t chase numbers without testing.

My torch’s tentacles are short and won’t extend—what’s causing it?

Common triggers are turbulent, blasting flow; sudden alkalinity swings; vermetid snails or stinging neighbors; and ultra-low nutrients. Shift to a broad, alternating flow that moves tentacles gently. Verify alk stability (8–9 dKH) and check for pests or nearby corals within sweep range. If recently moved or light-acclimated too fast, step back PAR and re-acclimate.

Can I keep Banana Torch with hammers or frogspawn in the same zone?

Use generous spacing—torches often sting even other Fimbriaphyllia. Night sweepers can reach 6–10 inches and pack a strong sting. Run fresh carbon and maintain good export to reduce allelopathy. Place torches down-current from sensitive corals, and avoid direct contact. Watch for micro-warfare: even brief tentacle touches can cause tissue recession on neighbors.

How do I handle brown jelly or sudden polyp bailout on a Banana Torch?

Act fast. Siphon the jelly, remove affected heads, and do an iodine dip; increase flow to prevent stagnation. Frag away healthy tissue from infected areas and discard dead skeleton. Stabilize parameters and avoid overfeeding. Some hobbyists use antibiotic baths (e.g., ciprofloxacin) in a separate container; if attempted, follow proven protocols and monitor closely.

Banana Torch Coral

Overview

Banana Torch Coral has long, bright yellow tentacles with darker tips and a torch-like look. Fimbriaphyllia glabrescens is a large‑polyp stony coral that does well under moderate light and moderate, indirect water flow. It relies on symbiotic algae for most nutrition but accepts small meaty foods, which can support faster growth and stronger color. Place it with space around the colony, as its sweeper tentacles can sting nearby corals, and secure it to prevent damage from strong currents.

Care & Placement

Banana Torch Coral (Fimbriaphyllia glabrescens) thrives with stable, reef-quality water and gentle handling. Provide moderate light (PAR ~100–200); acclimate to brighter tanks by lowering intensity or using a screen to prevent bleaching. Aim for moderate, indirect flow that keeps polyps swaying without blasting tissue; this helps avoid detritus buildup and bacterial issues. Feed 1–2 times weekly with small meaty foods (mysis, enriched brine) or fine coral foods when tentacles extend, typically after lights dim. Target parameters: 75–79°F (24–26°C), salinity 1.025–1.026, pH 8.1–8.4, alkalinity 8–9.5 dKH, calcium 400–450 ppm, magnesium 1250–1350 ppm, nitrate 2–10 ppm, phosphate 0.03–0.10 ppm. Use reliable test kits and a refractometer; avoid rapid swings, as torches respond poorly to instability.Place mid to lower in the tank depending on light, with strong emphasis on space: leave 6–8 inches around the colony due to long, stinging sweepers at night. Semi‑aggressive; avoid close neighbors, especially other Euphyllia types, and watch for clownfish hosting, which can irritate. Mount on a stable rock or rack; ensure the base is not buried. Dip on arrival, drip acclimate 30–60 minutes, and quarantine if possible. Signs of stress include retracted polyps, tissue recession, or brown jelly disease—improve flow, siphon affected tissue, perform an iodine dip, and maintain clean, stable water. If paling, reduce light, increase shade, and ensure nutrients are not bottomed out.
