Multi-Chamber Holding and Breeding Box: 10943

Easily attaching to the side of most aquariums up to 1″ thick, the Multi-Chamber Holding & Breeding Box provides up to 3 separate housing compartments for protecting fry, sick/weak or new fish that require acclimation

Compatibility

What it is. An external hang-on breeder/isolation box that divides into up to three separate compartments — for fry, injured fish, or a new arrival that needs to be kept apart from the main population without setting up a second aquarium.

Tank fit. Hangs on the outside of the tank. Fits frameless glass 0.25″–0.4″ (5–10 mm) thick, and framed tanks up to roughly 1¾″ (47 mm) at the rim — check your own rim thickness against those figures before ordering.

Water & livestock. Fresh or saltwater. The box draws and returns the aquarium’s own conditioned water, so it needs no separate heater or filter of its own — water quality inside tracks the main tank.

Specifications

Size. 10.25″ L x 5.5″ W x 4.75″ H (26 x 14 x 12 cm).

Capacity. Holds 0.5 US Gal (1.9 L) of water.

Chambers. Configurable as one, two or three compartments using the included partition plates, so the divisions can be sized to however many fish or fry groups need to be kept apart.

Setup & Use

Needs an air pump (roughly 1 L/minute, e.g. Fluval item A849) and airline tubing (item A1141), both sold separately — airflow drives water circulation through the box, there’s no powered pump built in. In the box: the housing with cover, three partition plates, two leveling adjusters, an air valve, 12″ of airline tubing, intake and discharge fittings, an O-ring, a strainer, cover clasps, and two sets of discharge plates — one for thick-framed tanks, one for thin-framed — so it seats correctly on either tank style.
