OG Bowsers Zoa Care Guide
OG Bowsers Zoa (Zoanthus sp. 'OG Bowsers') is a photosynthetic zoanthid morph kept in reef aquariums under moderate light and low flow; like all zoanthids it may contain palytoxin.

Overview
OG Bowsers Zoa (Zoanthus sp. 'OG Bowsers') is a named designer Zoanthus morph with a green skirt, an orange ring and a pattern of blue dots, circulated within private collections. Zoanthus, colloquially called button polyps or "zoas", are colonial polyps of the order Zoantharia. They are zooxanthellate corals: they host symbiotic zooxanthellae and obtain most of their energy from photosynthesis, while also exhibiting fluorescent proteins responsible for their bright colours. Trade morph names such as this one are hobbyist designations, not formal scientific taxa.
Taxonomy
- Order: Zoantharia
- Family: Zoanthidae
- Genus: Zoanthus (Lamarck, 1801)
- Trade morph: Zoanthus sp. 'OG Bowsers'
Habitat
Wild Zoanthus colonies spread across hard substrate on reefs, often forming brightly coloured mats that can cover a rock. Aquarium specimens of designer morphs are aquacultured rather than wild-collected.
Tank requirements
- Temperature: 24-26 °C (75-79 °F)
- pH: 8.1-8.4
- Salinity: 1.024-1.026 specific gravity
- Carbonate hardness: 8-11 dKH
- Calcium: 380-450 ppm
- Magnesium: 1280-1350 ppm
- Phosphate: below 0.1 ppm
- Nitrate: below 15 ppm
- Minimum tank maturity: ~3 months
Lighting and flow
Zoanthids do well under low to moderate lighting, with roughly 50-150 PAR suiting this morph. They prefer moderate, indirect water flow that keeps debris off the colony without blasting the polyps flat; this shard lists a low flow requirement. New lighting should be increased gradually to avoid light shock.
Feeding
As a photosynthetic coral it derives its primary nutrition from its zooxanthellae. It can additionally benefit from amino acids and fine particulate reef foods dosed to the water column, though supplemental feeding is optional.
Compatibility and growth
It is passive and lacks aggressive stinging tentacles, and is considered reef-, shrimp- and fish-safe. Reported growth is about 0.3-0.7 cm per month. Care difficulty is rated beginner.
OG Bowsers Zoa: Propagation Guide
Overview
OG Bowsers is a named Zoanthus morph (family Zoanthidae) with a green skirt, an orange ring, and a blue dot pattern, circulated within private collections. It is a trade-named color selection of these colonial button polyps rather than a separate species. The polyps of a colony remain joined by a stolon, or coenenchyme mat, and Zoanthus is known for displaying a large number of color morphs of the same or similar species.
Reproductive Mode
Propagation in aquaria is asexual. Colonies form because offspring polyps stay attached to the parent by a fleshy stolon, and the mat buds new polyps outward across the rock. This stolon budding is how an OG Bowsers colony naturally expands, without any sexual spawning.
Fragging / Asexual Propagation
- Select edge polyps and cut through the connecting stolon mat with a clean razor blade.
- Trace the cut with coral cutters until the section frees; a diamond band saw is used for thick rock bases.
- Soak and dry a plug or rubble, dry the frag base, then apply a little cyanoacrylate glue.
- Press the frag onto the plug, hold briefly to cure, then return it to the tank.
- New tissue and polyps confirm the frag has taken.
Conditions for Propagation
Zoanthus are hardy and adaptable, accepting lighting from lower to higher levels over roughly an 8 to 12 hour photoperiod. Healing frags prefer moderate to higher flow so the polyps are fed and waste is removed. As the stolon spreads, grouped frags merge into a colorful garden across the rock.
Palytoxin Safety
Zoanthids may contain palytoxin, among the most poisonous non-protein substances known. Wear gloves and eye protection during fragging, keep your hands off your face, and wash thoroughly afterward. Do not boil, heat, or scrape the rock, because heating can aerosolize the toxin for inhalation. No antidote exists; only symptoms can be treated.
Common Challenges
Freshly cut polyps may stay closed for several days while healing; consistent chemistry and gentle flow assist recovery. The green skirt, orange ring, and blue dots that define OG Bowsers can shift with lighting and water quality. The greatest challenge is safe palytoxin handling rather than the cutting technique.
