A colony that's outgrown a standard round plug needs a bigger mounting surface, and IceCap's frag discs and tiles scale that same porous ceramic-sphere construction up to fit multi-head colonies and larger specimens.
Why Scale Up From a Plug
Some corals - chalices, larger LPS colonies, multi-head zoanthid mats - simply need more mounting surface than a standard round plug provides. Discs and tiles give that growing surface without changing the underlying porous ceramic material coral tissue grows into.
Choosing a Format
- 1in Biological Frag Disc (25pcs) - a compact, porous ceramic-sphere mounting disc built for coral propagation, sized between a standard plug and the larger square tiles.
- 2in Biological Coral Frag Tile (15pcs) - a flat, square porous ceramic tile built for coral colonies that have outgrown a standard round plug.
- 4in Biological Coral Frag Tile (10pcs) - the largest format in IceCap's biological mounting line, built for sizable colonies, multi-head pieces, and larger specimens.
Suited Coral Types
This porous ceramic line works well across chalices, Euphyllia, green star polyp, high-light LPS and SPS corals, Montipora, softies, and zoanthids - essentially any coral that benefits from tissue growing directly into a porous mounting surface.
