Why does my Beetlejuice Bowerbanki inflate and “puff up” during the evening but stay tighter by day?

Homophyllia bowerbanki is a low-light, twilight-adapted LPS. It expands tissue at night to feed and protect valleys from detritus. Daytime contraction under brighter light is normal. If it never inflates after lights out, PAR is likely too high or flow too direct. Lower PAR to ~80–150, diffuse light, and adjust flow so tissue moves gently, not whipped.

The signature Beetlejuice colors look washed out—how can I restore the bold rings?

This morph holds color best under blue-heavy spectrum with moderate PAR and stable nutrients (NO3 ~5–15 ppm, PO4 ~0.03–0.1). Excess white light and ultra-low nutrients mute pigments. Ramp blue channels, shorten peak whites, and avoid rapid swings in alkalinity. Occasional spot feeding of fine meaty foods improves saturation over weeks. Avoid sudden spectrum changes—adjust over 1–2 weeks.

My Bowerbanki’s tissue is receding from one ridge; how do I stop a slow peel?

First, reduce light by 20–30% and soften flow. Inspect for vermetid snails or sharp rubble abrading tissue; remove offenders. Siphon trapped detritus from valleys. Perform an iodine or antiseptic coral dip, place in lower light, and increase random flow slightly to keep surfaces clean. Maintain stable alk 8–9 dKH and normal nutrients. If damage was from a cut, seal edges with a thin epoxy rim.

How far can its stingers reach, and which neighbors are most at risk?

At night, sweepers can reach 2–3 inches. Give at least that buffer from chalices, favias, and meaty LPS that lose flesh on contact. It tolerates most zoas and encrusting SPS at a distance but can overgrow slow encrusters if placed upstream. Run fresh carbon and maintain good export to reduce chemical stress in mixed tanks.

TSA Beetlejuice Bowerbankii Coral

LPS

Overview

Beetlejuice Bowerbanki Coral shows thick, fleshy polyps with ridged, round corallites and contrasting color bands. Homophyllia bowerbanki is a large-polyp stony coral forming encrusting to sub‑massive colonies; it 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 faster growth and color. Place on stable rock with space around it, as sweeper tentacles can sting nearby corals.

Care & Placement

Beetlejuice Bowerbanki Coral (Homophyllia bowerbanki) thrives in stable, nutrient-balanced systems with gentle conditions. Place it low to mid in the tank on a stable ledge or sandbed, horizontal for even light, with 3–6 inches of space from neighbors; it’s semi‑aggressive and can extend short sweepers at night. Provide low–moderate light (PAR ~60–150); start shaded and increase over 1–2 weeks to avoid bleaching. Flow should be low–moderate, indirect and pulsed to keep detritus from settling without lifting flesh. Target feed 2–4 times weekly at dusk when feeders extend using small meaty foods (mysis, calanus, chopped prawn) or LPS pellets; this boosts growth and color. Maintain temperature 76–79°F, salinity 1.025–1.026 (35 ppt), pH 8.1–8.4, alkalinity 8.0–9.5 dKH, calcium 420–460 ppm, magnesium 1280–1380 ppm, nitrate 5–15 ppm, phosphate 0.03–0.08 ppm. Avoid rapid swings; this coral is sensitive to instability and excess light.Acclimate with a 30–60 minute drip, inspect and dip for pests, and light‑acclimate with screen or reduced intensity. Test weekly; use a PAR meter or reliable app to confirm placement. Secure with putty or epoxy so colonies don’t fall and tear tissue. Signs of stress: paling/bleaching (too much light or too clean nutrients), tissue recession from edges (excess flow, unstable alkalinity, pests), browning (excess nutrients/too little light). Correct by shading, stabilizing parameters, modest feeding, and adjusting flow. Keep away from aggressive LPS like Galaxea and Favia; peaceful soft corals and zoanthids are fine at a distance.
