DescriptionStanding Frag Plug Holder – Zoa & Coral DisplayThe Standing Frag Plug Holder is a minimalist 3D-printed display solution for vertical coral frag mounting, emphasizing aesthetic presentation while maintaining functional water circulation. The design features a weighted base (3-inch diameter, 2-inch height) with 4-6 vertical slots capable of accommodating standard frag plugs in vertical orientation. This configuration enables compact display of zoanthids, palythoas, acans, and other colonial corals while maximizing surface area exposure to aquarium lighting and flow. Compact footprint suits nano reefs, frag-focused displays, or dedicated propagation sections.Installation: place directly on substrate; no anchoring required. Insert frag plugs vertically into slots and secure with minimal epoxy (one drop per plug). Expected utility: accommodates 4-6 coral frags in permanent vertical orientation. Frag positioning: mount strongest coral uppermost to maximize light exposure hierarchy. Water circulation passes through and around all frags; no dead-zone stagnation occurs. Compatible with frags ranging from 0.5 inches (emerging propagules) to 2 inches (established colonies).Tank compatibility: all reef systems, particularly nano displays (20-40 gallons) where footprint efficiency matters. Standing holders integrate seamlessly into rocky landscapes; corals appear to grow from natural rock faces rather than artificial supports. Pair with Zoa Puck with Zoa Frags] and Mushroom Coral Cage] for complete frag-propagation setup. This holder suits aquarists building personal frag gardens or hosting frag-swap events.Our team manufactures holders with weighted bases ensuring stability even in high-flow sections. Plug slots accommodate industry-standard frag-plug geometry (10mm diameter typical).Frequently Asked QuestionsQ: Can I position the Standing Frag Plug Holder horizontally for different aesthetics?A: The design assumes vertical orientation for optimal flow and lighting. Horizontal positioning reduces water circulation efficiency around frags.Q: How many coral frags can this holder display long-term?A: 4-6 frags maximum. Overcrowding reduces individual frag light access and creates current-dead zones.Why Vertical Frag Display MattersTraditional frag racks lay plugs horizontally, which works but limits coral polyp extension and light exposure on lower surfaces. Our standing frag plug holder positions each plug vertically, mimicking natural growth orientation and allowing 360-degree light penetration and water flow. This promotes faster encrustation, more uniform coloring, and better polyp extension compared to flat rack mounting. The design accommodates standard frag plugs (13mm stem diameter) and holds them securely without adhesive — simply press-fit and arrange.Design SpecificationsHolds up to 6 standard frag plugs per unit3D printed from reef-safe PLA material — no leaching, no off-gassingWeighted base prevents tipping in moderate flowCompatible with all standard 13mm frag plugsDimensions: approximately 4″ x 3″ x 2″ (fits nano tanks and frag tanks)Pair with our Zoa Puck for a complete coral grow-out display system.
