Acrylic Hang-On Breeding & Isolation Box — Fry/Shrimp Incubator & Refugium, Medium 2-Chamber (No Pump) / Large 3-Chamber (No Pump), Clear External Hatchery for Freshwater & Marine

Before You Buy: Two variants are available — Medium 2-Chamber (No Pump) and Large 3-Chamber (No Pump). Both use standard 3/16" (4/6 mm) airline.

Safe Haven for Fry & Shrimp: Protects newborns and timid species from tankmates; ideal for breeding, acclimation, quarantine, or separating aggressive fish.

Modular Chambers, Flexible Layouts: Removable dividers create up to 2 or 3 rooms for pairing, hatching, or isolation—arrange space as your stock changes.

Space-Saving Hang-On Design: Mounts externally on the tank rim so it won’t take up display space; quick to lift off for cleaning or repositioning.

Gentle, Air-Driven Circulation: Airlift flow refreshes water and boosts oxygen. Works as a marine refugium too—hold macroalgae to help stabilize nutrients and shelter pods.

Clear, Durable Acrylic: High-transparency panels let you monitor behavior at a glance; smooth edges and lift-off lid make feeding and maintenance easy.
