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. Read more

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. Read more

The media could not be loaded. 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. Read more

This worked very well Read more

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. Read more

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. Read more

Used the Fluval Multi Chamber Box (large) for a separation tank due to one of our fish needing some rehab/alone time. Tank is easy to install - literally you just pop it on the rim of the tank - and we made sure we double checked measurements pre ordering. Water flows in and then out of the lower exit "slide" easily and there is a cover with a hole so you can feed your fish. Came with the dividers (we haven't needed to use these yet). The aeration IS loud if you have the valve on high (and some fish/medical treatments etc require high aeration). One of the adjustments we'll make is the entrance tube for the aeration doesn't go into the tank (it sits right above the surface) so you get loud gurgling noises and upper vibration of the water vs air bubbles in the water like a aeration stone. We'll add an attachment so it's under the water making it quieter and circulating a bit better. Ultimately a good purchase and we've used it no problem. *Will use this for plants after fish has rehabbed so tank will continue to get used in the long run. Read more
