Description

The Fluval Multi-Chamber Holding and Breeding Box is ideal for those looking for a convenient way to separate fish from the tank. This is usually done during breeding and as a maturation tank for young fry; but there are other times when fish may need to be isolated. This box does this without taking up space in the tank. Keeping perfect aquatic harmony has never been easier.

  • Works great!
Size: Large Product Packaging: Standard Packaging
I love it. Easy to set up and it works great. I read some reviews that it does not keep fry in the holding tank and they get back into the main tank through the overflow. Two ways to resolve that. 1) Don't fill it all the way up so that its constantly overflowing. Or 2) they make an insert to slide in that supposed to keep fish from swimming out the over flow. I took the insert and cut a piece of 250micron filter bag that I had lying around and glued it over the insert so that the fry would not be able to swim through the slits of the insert. It works like a dream and I never have to worry about my fry escaping back into the community tank. ... show more

  • Fantastic breeder box that needed some modifications on my end.
Size: Large Product Packaging: Standard Packaging
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! ... show more

  • Great product with multiple uses
Size: Large Product Packaging: Standard Packaging
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. ... show more

  • The best invention for the aquarium hobby since glass!!
Size: Large Product Packaging: Standard Packaging
I bought one of these for my angelfish breeding. I have some pairs that throw a percentage of albino fry and could never manage to get any of the albinos to survive until I tried one of these breeding boxes. Now, I am getting unbelievably high survival rates with my albino fry! I now have three of these and a fourth one is on it's way! And they are very affordable. I can't say enough good about these boxes. They really simplify raising fry. They are VERY easy to clean and maintain. They can be used not only as breeding/fry boxes, but also as slow-drip acclamation devices, isolation tanks for stressed or "bullied" fish, and great holding tanks for taking pictures of your fish, and the added benefit of having the stability of the larger tank that the box is hanging on is priceless. To do a water change for your fry, simply do a water change in the main tank, and you never even have to move the fish in the box or worry about them during water changes. As I mentioned already the price is fair, not too expensive at all. The instructions were simple and the design is brilliant. The only cons I guess I can think of are that you can't use a top for the tank they are hanging on unless you devise a custom top that can fit around the part that hangs over the front of the tank. The other thing is that they come with tow "grates" that cover the overflow, one with small gaps for smaller fry, and one with larger gaps for once the fry are grown out a little. The problem with the grate covers with angelfish is that even with the smaller gapped grate, fry can squeeze through and get washed back into the main tank. To remedy this I bought some foam sponge from hobby lobby and cut small squares to replace the grate for the first week or so until the fry are too big to fit through the gaps. You will want to cut the foam sponge pieces to fit snugly but not tightly enough to restrict too much water flow otherwise you can overflow the box and wash some fry back into the tank that way. With a little adjusting of the trickle and just the right size sponge block, you can keep the fry in the box no problem. As great as these are I can't justify taking away a star for that little issue. If it weren't for these breeder boxes I wouldn't be able to raise the albinos... at least not without quitting my job and tending to them full time! ... show more
