Breed, isolate, and acclimate fish or shrimp in this safe and secure nursery. Marina Hang-On Breeding Box is directly attached to exterior of your aquarium, so juvenile fish are acclimated but still protected from adult fish. Space saving design allows only juvenile fish to slip through the separator. Warm oxygenated water from the main aquarium is circulated through the breeding box with an air pump (sold separately). No additional filters or heater are needed. 

Create up to 3 separate compartments using included partition plates. 

Measures 10.25 inches wide and holds 0.5 US gallons of water. 

An air pump (1L/ per minute) and airline tubing are required and not included.

hang-on breeding & holding box


Working out great. I raise guppies and they have had baby's already.

seperate use


Can I use ths aquarium to display catfish in my store
Pls note that I ll need to dip hand into the aquarium to bring out desired fish to customerand as well I ll need to always drain water and refill

Well thought out!


This is a great little unit, with some good applications. Well constructed, and well thought out design. Highly recommend it. Have two, and would seriously like a few more.

Great item


I saw this and thought that I’d give it a try to segregate my neocardina and cardina shrimp Works great, adjustable water flow, everything is neat and tidy, and no worries of losing anything to a water change, great for eggs/fry. Worked so well I purchased another. Wish it came in a gallon size

breeding box


This is an awesome little unit. I use it for raising corycatfish fry. The adjustable airflow is great for eggs and newly hatched fry. I would actually like a few more of these and would recommend them to anyone breeding fish

Just the best!


Best breeding box I have ever used! Got one and ordered 2 more. Only problem I see is that it hangs on the outside of the tank. My fish room is unheated and the water gets too cold to use it in the winter. Would have been SIX stars if it could go on the inside or out. Well worth the price!
