Why does my Blazing Sun Cycloseris inflate and deflate dramatically, even moving a bit on the sand?

Cycloseris sp. are free-living plates that inflate their tissue to shed sand and detritus or to reposition away from irritation or light that’s too intense. Brief “ballooning” is normal. If it’s frequent, reduce flow slightly, shield from direct blast, and lower light by 10–20%. Check nearby sand-sifters that may be burying it.

My coral is paling near the mouth but still expands—what’s the likely cause?

Central paling often points to excess light or underfeeding rather than disease. Shift it to lower PAR (moderate, indirect), extend the blue photoperiod, and target-feed small meaty foods 2–3 times weekly. If tissue thins, try an iodine dip and improve stability (alk/cal/mg). Avoid aggressive peroxide or long-duration dips.

How do I keep sand and grit from irritating it on the substrate?

Use fine, clean sand and set the coral on a shallow ceramic tile or “coral cradle” slightly proud of the bed. Tune flow so it’s gentle, cross-current rather than direct. Keep burrowing gobies and pistol shrimp from its zone, and gently baster-blow debris off weekly. The coral can expel some grit, but chronic burial stresses it.

My coral browned out after increased feeding—did I overdo nutrients?

Likely a combo of higher nutrients and lower light at the tissue. Reduce particulate foods, keep target portions small, and boost export (skimming, refugium, weekly 10–15% changes). Gradually raise PAR 10–15% over two weeks and favor a blue-heavy spectrum. Once stabilized, resume light feedings; color typically improves in 2–4 weeks.

Overview

Blazing Sun Cycloseris Coral shows a flat, round disk with radiating ridges and a bright orange to yellow surface. Classified as Cycloseris sp., it is a solitary free-living large-polyp stony coral; provide moderate light and low to moderate, gentle water flow. It hosts symbiotic algae for photosynthesis but accepts small meaty foods, which can support faster growth and deeper coloration. Place on the sandbed with space around it, as its tissue is delicate and can be damaged by sharp rock and nearby stingers.

Care & Placement

Blazing Sun Cycloseris Coral (Cycloseris sp.) thrives under stable, clean conditions with moderate nutrients. Provide moderate light (PAR 60–120); start lower and increase slowly over 2–3 weeks using a light acclimation screen to avoid bleaching. Gentle to moderate, indirect flow keeps detritus off the disk without lifting the coral. Target feed 2–3 times weekly after lights out with small meaty foods (mysis, chopped krill) or fine coral foods; feeding supports growth and color. 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 400–450 ppm, magnesium 1300–1400 ppm, nitrate 2–10 ppm, phosphate 0.02–0.08 ppm. Use reliable test kits, a refractometer, and, if possible, a PAR meter. Avoid rapid swings; this coral is sensitive to instability and copper.Place on the sandbed with at least 3–4 inches of clearance from rocks and neighboring corals. Do not wedge on rock; sharp edges can damage tissue, and the coral may inflate and move. Keep away from corals with long sweepers (galaxea, favia, many torch/hammer types). Gently baste away debris every few days. Acclimate via drip (30–45 minutes), then dip in a coral-safe bath to reduce pests. Watch for signs of stress: gaping mouth, tissue recession, or faded color; reduce light, improve flow, and feed lightly if observed. Prevent flips by moderating flow and smoothing coarse substrate; promptly upright if overturned. Avoid fragging; Cycloseris heals poorly from cuts.
