This is a great box for my Angel fish fry! I did get a small submersible water pump because using the air pump was too noisy for me.

Interesting and good-looking construction. My fry is safe, although it makes a little noise, this is unfortunate but bubbles are pushing water into the breeding box so it cant be helped.

Very happy with this product
Yet another simple but effective product. I read the reviews and am currently putting it to the test. However, for use as a fry tank to keep fry in the same water conditions as hatched with parents, this is great. Water flow by air pump is slower I can see the use of a small powerhead pump. This will do the job more effective than in a floating breeder.
Great hang on breeding box, I currently use it to pair up shrimp for breeding, looks great works well, highly recommend this breeder box for shrimp 🦐 thank you
I like the solid design and the easiness of assembling the additional parts. I use it as a HOB filter instead of a breeding box.
Assembly was easy, and this product works perfectly. Hangs on the side of your existing tank and keeps fish separated and safe. Uses the aquarium water so it is warm and the bubble tube gives it a flow. Love this product!
Used the hang on box for fry. Lost several fry a couple times from getting through over flow.
This product worked out great as a Hang-On Refugium for my 20g Reef aquarium. I tried it with an air pump at first and although it has flow, it is lacking quite a bit; not to mention it is quite noisy. I swapped out the air pump for a small internal pump and it fit very well and had great flow for use as a Refugium. I also added a small power compact light fixture to keep the Macro Algae alive and
