Why does my Battletoads Plate Coral (Cycloseris sp.) inflate and “walk” across the sand, and should I let it?

Cycloseris can inflate to self-right and subtly “walk” to find better flow or light. Allow movement as long as it’s not drifting under rock ledges or into high-sting neighbors. If it repeatedly moves, reassess placement: slightly higher laminar flow to keep it clean and moderate light. Use a smooth sandbed; coarse grains can abrade tissue and trigger recession.

My coral’s mouth looks gaping after a meal. Is that a problem with Cycloseris?

A temporarily gaping oral opening post-feeding is normal. Issues arise when large food tears the mouth or detritus lodges there, leading to rot. Feed smaller items (mysis, small pellets) and gently baste away leftovers after 15–20 minutes. If mucus accumulates or tissue recedes from the mouth, consider an iodine-based dip and reduce feeding size/frequency.

Does Cycloseris prefer intense light like some plate corals, or will that bleach it?

Many Cycloseris color morphs prefer moderate PAR with strong blue spectrum but can bleach under sudden high intensity. Acclimate over 2–3 weeks using lower photoperiod or screen. Color often deepens under stable blue-heavy lighting with modest nutrients (not ULNS). If fading, slightly reduce white channels, increase targeted feeding, and verify nitrate/phosphate aren’t bottoming out.

How do I prevent sand-related tissue loss on the underside and ridges?

Keep a clean, fine-grain substrate and provide enough flow to lift silt without flipping the coral. Avoid burrowing fish nearby. A low-profile acrylic ring or ceramic “riser” under the disc prevents edge abrasion and detritus trapping in ribs. Turkey-baste weekly. If recession starts, move to cleaner flow, perform an antiseptic dip, and avoid handling the tissue directly.

LPS Plate Coral

Overview

Battletoads Plate Coral shows a flat, round disk with short radiating ridges and a central mouth. Cycloseris sp. is a solitary, free-living hard plating coral that prefers moderate light and gentle to moderate water flow. It relies on symbiotic algae for most nutrition but accepts small meaty foods, which can support growth and color. Place on sand or a stable bare area away from aggressive neighbors, and keep debris off the tissue.

Care & Placement

Battletoads Plate Coral (Cycloseris sp.) thrives with stable, moderate conditions and gentle handling. Place it on the sandbed or a flat tile/rubble piece in a low, open area; avoid rock ledges where it can fall. Provide low–moderate light (PAR ~80–150) and low, indirect flow—enough to keep debris from settling without flipping the coral. Target feed 2–3x weekly after lights out when feeder tentacles extend; use small meaty foods (mysis, finely chopped seafood, pellet) and turn off pumps for 10–15 minutes. Keep temperature 24–26°C (75–79°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; maintain nitrate 2–15 ppm and phosphate 0.03–0.10 ppm. Monitor with reliable test kits, refractometer, and a temp controller; avoid rapid swings, especially alkalinity and salinity.Acclimate slowly: drip 30–45 minutes, light acclimate over 1–2 weeks to prevent bleaching. Dip for pests per product directions, keeping exposure to air brief and supporting the tissue; handle by the skeleton edge. Give 3–4 inches of space—though generally peaceful, it can sting on contact at night. Keep sand-displacing fish, large hermits, and urchins from burying or overturning it. If you see tissue recession or gaping mouth, reduce light/flow, increase feedings, and check parameters; if detritus accumulates, gently baste. Consistent care, moderate nutrients, and regular night feedings yield strong color and steady growth.
