Fluval Multi-Chamber Holding and Breeding Box, Large – Up To 3 Separate Housing Compartments

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.

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.

Came with one of dividers tab broke

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.

This worked very well

Not good for trying to hatch out egglayer eggs. Slats in dividers and gates are spaced to far apart allowing baby fry to escape into next chamber and out the box and into tank. Also, it's very noisy if you have water intake turned up all the way. Also, water flowing into breeder box has debris from fish tank.

Since my crayfish seem to breed quite often, I decided to get this box so the babies don't get eaten. The breeding box is quite sturdy and durable. The suction does a good job of holding the tube for water. The assembly was easy. A little noise is made when water is pushed into the box using air. It is just the right size for lots and lots of baby crayfish.

The Fluval Multi-Chamber Holding and Breeding Box (Medium) is an incredibly well-designed accessory for anyone who keeps fish, breeds them, or needs a safe space for fry or injured tank mates. The multiple compartments offer great flexibility — you can separate fry by size, isolate a stressed fish, or use it as a temporary acclimation area. One of the best features is the continuous water flow from the main aquarium, which keeps the environment stable and oxygen-rich without stressing the inhabitants. Setup is very simple, and the box attaches securely to the tank with no wobbling. The clear plastic allows easy monitoring, and the layout makes feeding and maintenance effortless. Overall, this breeding box is sturdy, thoughtfully designed, and extremely versatile. A must-have for breeders, hobbyists raising fry, or anyone who needs a reliable isolation space. Highly recommended! 🐟✨

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.

This has made my guppy breeding experience so much easier. It was very hard to remove fry from the traditional mesh breeding boxes. Plus the material itself would grow algae, get a dirty oil film on top and was difficult to clean. It also was difficult to remain attached with cheap suction cups. This external breeding box is amazing! Can see more clearly, feed them with ease, i can clean mess from bottom of box with a turkey baster, without disrupting the fry and it just tops itself up. It is easy to net the babies out once they are old enough for the community tank. And so easy to feed multiple times a day for younger fry - as you only have to turn off the air pump, rather than all the filtration too. This has been one of my best fish keeping investments!

werkt gewoon goed en heel goed om eieren uit te broeden
