Aquarium Breeder/Fry/Isolation Box

Item highlights

  • Materials: PLA
  • Made to order

Seller's description

Easily and quickly isolate fish, hatch eggs, and raise fry in our air pump driven breeder/fry/isolation box. We offer 4 sizes to custom fit your needs. Simply attach your air pump and air tubing (1/4" OD) (Not Included) into the port on the top of the box, and with the included adjustment valve, tailor the flow to your needs. Will not fall/release contents during water changes. We've raised numerous batches of Corydoras fry in our fish room using these boxes and have had great results!

***Aquarium in which the breeder box is placed should be filled appropriately to maintain proper breeder box performance. Aquariums which are not filled at least to the bottom of the black aquarium rim may result in poor water uptake into the unit, and potential damage to the mounting hooks. ***

NOTE: The attachment hook is designed to fit up to a 40 gallon Aqueon rim. For additional rim options, please reach out to us with your specifications, and we'd be happy to custom fit the product for you.

Now I have 4 of the white fry boxes and enjoy how well built they are. I added a uptake foam filter. Yes, you can really see the "stuff" that you have naturally in your water.
