Review: Easy to set up! Fits 75 gallon tank! Plenty of inflow & outflow! - I love this little box for my pregnant shrimp! It easily fits onto my 75 gallon aquarium. I currently have 5 pregnant shrimp in here. They seem to have plenty of room, for now. I’m not how this will work or if I’ll be able to save babies. I’m certainly going to try. The box was super easy to set up. It only took a few minutes. I was worried because the directions said the aquarium water level had to be within 2” of the top. Mine is not. I have it lower than that. Thankfully, it works just fine. I get a steady stream of water pumping in and flowing out. I think this little box is genius! I’ll probably use it to house some plants or maybe other fish babies, in the future. Also, I wrapped a little quilt batting around the output to prevent anything from getting dumped back into the aquarium.
Review: Fantastic breeder box that needed some modifications on my end. - So I've bred peacock gudgeons and hatched most of the eggs within this container. It was attached to its own little 5 gallon tank with a HOB with carbon and extra sponge for proper filtration, keeping nitrate and nitrite at 0 despite the several-times-a-day feedings. The box definitely has potential to turn your fry container into a fry washing machine, little guys get tumbled around from the flow. The little adjuster on the airline itself did nothing for me, so I had mine hooked up to the system of my rack that let me change airflow directly from the pump. Had to lower that a decent chunk, otherwise the water flow was simply too strong. Even with that, I put some aquarium sponge on a little skewer and placed it right under the water output to catch most of the impact. I also added a piece of sponge on the outflow, because the little grate it comes with is just too big. My little fry kept escaping. I eventually learned that my fry are even small enough to go into and through the damn sponge I put in there, so I had to use something finer (which clogged easier). I also added some floaters and java moss to help with both filtration and hiding space for my little buggers. Unless you have fry that's too big to go through the little grate you definitely will need modifications. But besides all that, it's a fantastic option for hatching eggs and raising fry. My little guys are by now big enough to swim in the 5g freely while growing a little more without risk of ending up in the HOB. Given how well this entire setup worked for me I'll be getting more in the future. I've yet to try it for egg scatterers along with the one item from I believe penplax for automatic egg-harvesting, but I'll get there. And for that I'll need another one! I definitely can recommend it. It kept all my fry in a small space meaning I could give them more accurate feedings, and hook it up to its own tank to have a big water volume for great parameters. Amazing!

### ⭐⭐⭐⭐ Great product with multiple uses
*by M***L on June 10, 2024*

I've been using the 0.5 gallon breeder box for a few months now and it has worked really well so far. I use it for drip acclimation, as a holding tank for new fish/shrimp, and as a breeding tank to raise fry. It is very convenient, efficient, and easy to set up. Many of the negative reviews mention the little gate piece allowing fry to escape into the main tank. This is easily remedied by adding a piece of sponge filter in front of the gate. It is a little bit on the noisy side, but I actually enjoy the sounds of bubbles and trickling water. Other than that, the only two issues I have is that the the male connection to the airline tubing can get clogged with bacteria/biofilm which reduces the flow. This can be fixed by simply cleaning it with a test tube brush. Flow is also reduced if the water level in the main tank is lower, so just keep that in mind. The other issue is that waste can accumilate on the bottom of the chamber and it is not efficiently removed. I say this because all of my cory catfish fry died presumably because of the excess bacteria buildup on the bottom of the chamber. However, I probably overfed with first bites and didn't do a good job of siphoning out the waste. Despite these potential drawbacks, I believe that this breeder box is the best on the market.
