The AvidAqua Manta Ray Frag Rack is a sleek, low-profile magnetic rack for growing out coral frags in display tanks or sumps. Its manta-ray silhouette maximizes usable space while keeping flow paths open, so frags get light and circulation without cluttering your aquascape.
Magnetic mount for easy placement and repositioning (check pane-thickness rating)
Reef-safe construction—CNC-cut acrylic with sealed, epoxy-coated magnets
Low-profile design that minimizes shadows and dead spots
Standard plug fit—accepts most ½″ (≈12–13 mm) frag plug stems
Chamfered/rounded holes for snug, upright seating
Removable & cleanable—lift out for quick maintenance
Choose a spot with good light and moderate flow (avoid direct blast).
Clean the glass/acrylic where the rack will mount; remove film and salt creep.
Attach the rack: place the wet side inside the tank and align the dry side outside.
Load frags—seat plugs fully so they stand vertical.
Acclimate new frags to light by starting lower or off-center and moving upward over 1–2 weeks.
Tips
Leave 1–2″ between frags to prevent stinging and allow growth.
For heavy colonies, place them closer to the magnet side for stability.
Periodically lift and brush off detritus; soak in tank-temperature RO/DI if needed.
Rinse with fresh water after handling; do not expose magnets to harsh solvents.
Inspect the magnet encasement; discontinue use if the coating is compromised.
Avoid trapping sand/grit between the rack and glass/acrylic.
