OceanBox Designs Ceramic Frag Plugs
OceanBox Designs' ceramic frag plugs stake a best-in-class position thanks to finely finished, porous ceramic that promotes coralline and biofilm growth while providing a snug, tapered fit for stable mounting of corals and live plants. They command a premium price compared with the more economy-oriented options on this list, but their consistent dimensions, aesthetic finish and material benefits make them a worthwhile investment for reefkeepers seeking long-term stability and better biological integration. Compared with bulk or plastic alternatives, OceanBox plugs excel technically in porosity and finish, which encourages faster encrustation and natural-looking frags.

Two Little Fishies CorAffix Frag Mounts
Two Little Fishies' CorAffix mounts are a market-leading choice for hobbyists who prioritize speed and flexibility, featuring user-friendly geometry and adhesive-friendly surfaces that make placement and rearrangement quick and repeatable. They are often more budget-conscious than premium ceramic plugs, and their versatile design works well for both coral frags and attaching small live plants, giving a cost-effective alternative to ceramic while sacrificing some of the long-term porosity benefits. Compared to OceanBox and ceramic discs, CorAffix stands out for convenience and lower upfront cost, making it a strong option for frequent fraggers and mixed-use aquascaping.

Boston Aqua Farms Ceramic Frag Discs
Boston Aqua Farms' ceramic frag discs are known for consistent, low-cost bulk production that makes them ideal for farms, clubs and hobbyists who need large quantities without breaking the bank. Technically they offer a flatter, wider surface that favors encrusting corals and anchoring larger plant bases, though they are typically less finely finished and slightly less porous than premium ceramic brands. Financially they undercut premium options like OceanBox and match well with Bulk Reef Supply for volume purchases, making them the practical choice when per-piece cost matters most.
Broad flat disc — strong base

They’re considered a top pick for consistent, economical ceramic discs."
Natural white finish — photo-friendly

Eshopps Frag Cave Plugs
Eshopps Frag Cave plugs differentiate themselves with a unique cave-style geometry that creates protected microhabitats ideal for encrusting corals, small LPS/SPS species and certain live plants that prefer shaded attachment points. They occupy a niche role compared with flat discs and standard plugs, providing a technical growth advantage for species that thrive in overhangs while remaining moderately priced for hobbyists seeking specialized mounting options. Financially and functionally they complement the other products—used alongside flat plugs from OceanBox or Boston Aqua Farms, the Frag Cave expands the range of mounting strategies for mixed reef and planted setups.
