Great Breeder Box for Raising Fry
This breeder box has been perfect for raising my celestial pearl danio fry. It was easy to assemble, and I really appreciate how simple it is to access the inside for both feeding and cleaning. I did make a small modification by adding a sponge to the return since the provided grates were a bit too large and could allow fry to slip through. With that adjustment, it works wonderfully. Overall, I highly recommend this breeder box for anyone raising fry.

A Tiny Aquatic Condo With Adjustable Plumbing (Worth the Assembly-Induced Existential Crisis)
I have to be honest: when I opened the box, saw what felt like one million tiny plastic pieces, and realized I was expected to assemble this thing myself, I was instantly overwhelmed. Maybe I was just in a mood. Maybe I had already exceeded my daily allowance of minor inconveniences. Either way, I was not emotionally prepared to open the box and find a tiny 3-D plastic jigsaw puzzle with its own plumbing. Thankfully, the instructions were clear, everything fit together properly, and I was able to assemble it without much difficulty. Was I cheerful about it? No. Was it actually hard? Also no. I was simply being dramatic. Once assembled, though, I was genuinely impressed. This box is extremely well engineered and feels sturdy and well made. It includes a bottom insert that can be used to allow fry to drop beneath it and remain separated from the parents. It also comes with two divider panels, so the box can be configured into as many as three separate chambers. I am not currently using the bottom insert or the dividers, but I appreciate having those options. There is also an additional grate that helps prevent tiny fry from escaping through the outlet and returning to the main tank, where they would presumably discover that life is cruel. One of my favorite features is the adjustable water-flow control. Water slowly drips into the box and then flows back into the aquarium, providing continuous circulation without turning the enclosure into a tiny aquatic water park. The flow can be adjusted to a very slow, gentle rate, which is ideal for fry or other delicate inhabitants. One important thing to know is that an air pump is required to operate the continuous water-flow system, and the pump is sold separately. Fluval does make that clear, so it was not an unpleasant surprise, but make sure you already have a compatible air pump or purchase one along with the box. Without it, you will not be able to use the slow, adjustable circulation feature, which is one of the best things about this setup. I am actually using mine to house and breed California blackworms rather than fish fry, and it works perfectly for that purpose. I placed a shallow layer of gravel directly in the bottom of the box without using the bottom insert. The worms remain completely separated from the rest of the aquarium while still receiving fresh, filtered, continuously circulated water. The holding box also stays comparatively clean, which is impressive considering blackworms are not exactly known for respecting housekeeping standards. Overall, this is a thoughtfully designed, versatile, and highly functional breeding and holding box. It does exactly what I hoped it would do and gives me far more control than a basic breeder net or container. 10/10, absolutely recommend… even though assembly is required. (It really was not difficult. I simply needed a moment to process the betrayal.)

Great product with multiple uses
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.

Don't put your flow too high. Use the correct angle.
So as you see in my video I have experience with the small, and now I own the large version of this breeder box. It works great. Some reviews say people had issues. As you see, it doesn't leak and the pegs didn't break off like some others said. The pegs add and remove leverage so that it can sit correctly. You want it to be aligned perpendicular with the rim of your tank or if anything SLIGHTLY angled downward INTO the tank. You do not want the bottom of the breeder box to be pushed out from the tank. I could see that as a reason why the pegs would break for some people. You don't want the bottom too far in. I could see that causing the box to leak from the front but I dont see how that could ruin your marriage. I have my pegs on number 4 but the glass and rim is thick on my 75 gallon. Front of the breeder box should be more or less parallel with the tank. Don't put your flow too high. I have a constant drip. Maybe 1 to 4 drops per second but it needs to be dripping into the box constantly. It gives a small stream from the slit and a constant drip into the aquarium. It doesn't make lots of noise. I haven't had issues with this method in 2 years. This combined with my egg incubator is invaluable when it comes to preserving numbers. The small version does not have a lock. I don't use the lock on the big one. I dont like the design of it. I didn't need instructions because I'm not incompetent but some people may need them.

Great quality
I really like this breeder box. We used to have one that sat in the tank and you would have to manually pour water into it to clean it. I really like how this one keeps the water clean on its own. I bought the large breeder box to house five baby pea puffers while I wait for my other tank to finish cycling. I saw a lot of people complaining about it being loud, but I don’t think it’s loud at all. It’s made out of very sturdy plastic and I like how it can be adjusted to fit different size tanks. The instructions aren’t great, but if you look at the pictures, you can figure it out.

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.

didn't keep the fry separated...
Seemed like a good idea, but the fry went right through all the strainers and right into my main tank. Worked great to isolate the mother, though.

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!

One of the best Holding and breeding box
I have tried different types of breeding boxes and I consider Fluval holding and breeding box the best among them. It has everything that you need for an aquarium hobbyist. The size is very convenient comparing to others while I wish if Fluval can make a bigger size also. This is a complete set and you won't regret buying it. I highly recommend it.
