Hang On Breeding Box

Description

Fluval Hang-On Observation Box

  • Ideal For Observing New Corals Before Adding to the Aquarium
  • Provides a Safe Haven for corals being Picked on by Fish
  • Hangs on to Exterior of the Aquarium for Easy Observation

 

Easily attaching to the side of most aquariums, the Hang-On Observation Box provides an isolated area where you can easily observe the coral or invertebrates inside. Due to its size, most saltwater fish will be too large to be housed inside for an extended period of time. 

The box is air driven, so an air pump will be necessary for operation (sold separately). Fluval recommends a 1L/minute air pump. A valve to control the air flow is included. 

 

Max Glass Thickness: For use with rimless aquariums with a glass thickness of 0.25-0.4" and framed aquariums less than 1.75"

Dimensions: 6.5" L x 5" W x 4.75" H

Volume: 0.3 Gallons
