Why does my Dragon Claw Birdsnest lose tissue at the base while tips keep growing?

This coral shades its own base as branches thicken. Low light and reduced flow around the base encourage slow tissue loss. Prune to open the colony, increase cross-flow, and avoid crowding with nearby corals. Mount higher on the rockwork with space beneath. Keep alk stable (around 7.5–8.5 dKH) to reduce stress that accelerates recession.

What causes “burnt tips” or sudden tip die-off on Seriatopora hystrix?

It often follows a combo of high alkalinity, very intense light, and ultra-low nutrients. Tips bleach and then recede. Reduce light slightly or shorten photoperiod, bring nutrients into a modest range (e.g., detectable NO3/PO4), and keep alk steady rather than high. Improve random flow; avoid direct laminar jets striking branch tips.

How can I maintain bright pink or green coloration without browning or paling?

Provide strong but not scorching light, turbulent flow, and balanced nutrients—enough nitrate and phosphate to prevent paling, but not so high that zoox density browns the coral. Occasional feeds of fine plankton or amino acids can support color. Stability matters more than chasing high PAR; gradual adjustments prevent shock-induced fading.

Are there unique compatibility concerns beyond general SPS guidelines?

Long-sweeper LPS can scorch branches quickly; give extra room down-current. Soft corals may release chemicals that irritate Seriatopora—run carbon and change it regularly. Avoid direct contact with aggressive Pocilloporids. A mature, stable environment limits bacterial issues that can trigger rapid tissue loss after minor stings or parameter swings.

TSA Dragon Claw Birdsnest Coral

Birdsnest SPS

Overview

Dragon Claw Birdsnest Coral shows thin, densely interwoven branches with sharp, claw-like tips. Seriatopora hystrix is a small-polyp stony branching coral that prefers strong lighting and brisk, turbulent water flow. It relies on symbiotic algae for energy but benefits from occasional feeding of very fine plankton, which can support growth and color. Place high and in stable, low-nutrient conditions, allow space from stinging neighbors, and handle gently as branches are brittle.

Care & Placement

Dragon Claw Birdsnest Coral (Seriatopora hystrix) thrives under strong, stable reef conditions. Provide high, stable light (PAR 200–350) and vigorous, random flow to keep branches clean and oxygenated; avoid direct laminar jets that can strip tissue. It is largely photosynthetic but benefits from occasional small-particle feeds (rotifers, reef snow/reef roids, and amino acids 1–2x weekly). Maintain temperature 24–26°C/75–78°F, salinity 1.025–1.026, pH 8.1–8.4, alkalinity 8.0–9.5 dKH, calcium 420–460 ppm, magnesium 1300–1400 ppm, nitrate 2–10 ppm, phosphate 0.03–0.08 ppm. Test weekly and dose to keep numbers steady; swings cause paling, RTN/STN, or branch tip burn. This species is sensitive to rapid changes, very low nutrients, and low flow that allows detritus buildup.Place frags high to upper-mid in the tank with strong, turbulent flow. Give 2–4 inches of space; the bushy growth can shade neighbors and may sting on contact. Keep away from aggressive LPS with long sweepers (e.g., euphyllia, galaxea). Acclimate slowly: dip and inspect for pests (look for Seriatopora-eating nudibranchs), mount securely, start in moderate light and increase over 1–3 weeks. Use an ATO for salinity stability and a PAR meter or light acclimation mode to prevent bleaching. If tissue recession starts, check alkalinity and flow first, then inspect at night for pests. Fragile branches break easily—handle by the plug, not the tips, and maintain stable parameters for steady growth and strong color.
