## Description

The Fluval Multi-Chamber Holding and Breeding Box is ideal for those looking for a convenient way to separate fish from the tank.

Keeping perfect aquatic harmony has never been easier.

Review: Works great - Easy to install works greats
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!

## Questions & Answers

**Q: What are the dimensions of the box?**
A: 6.5"L x 5"H x 3.5"W.  If you include the part that hangs on to the tank the width is 5".  You can only fill water up to a height of 4" before the water spills back into the tank in the overflow channel.

**Q: how do I separate mama guppy and babies? it seems different with the medium size breeding box and I am so confused how it works...**
A: Apparently the sizes are not being represented correctly by Amazon. The small through medium versions are actual breeder boxes where pregnant female can give birth and the fry it seperate by a v birth gravity fed system to seperate the fry from the mom. The large breeding box can be used as isolation fry raising rearing or to breed fish in it in a confined space where males can fertilize the females. The large comes with 2 dividers to create 3 seperate housing area to grow out fry. I was Lao misled about this thinking all the sizes were the same but small and medium are one type and large is used as an external isolation tank. Hope this helps future buyers. I know amazon gets picky when you return things and has threatened to close my account over it but when a big company like this doesn't know the product it's actually selling and groups it together with all sizes it will create confusion to the consumer and in turn we get penalized for it or may have to pay return shipping. Those return shipping fees are the price of this plastic so it's not worth it to return. Nice product but now I need to buy a medium also because it's really what I needed with a very birth chamber to seperate fry from being eaten. Sucks wasted money.

**Q: What's to stop the fry from washing into the main tank with the returning water?**
A: You must place a piece of sponge on the intake and in front of the grate of the water return to guarantee the safety of the fry.

**Q: Can mollies fit in the small breeder box**
A: yes they can, not many of them though. we kept our fish in their regular tank and once the female mollies were pregnant we moved the pregnant ones to the breeder box only about 2-3 of them. It is pretty small.

### ⭐⭐⭐⭐ Great, if you fix the sputtering
*by A***S on October 9, 2017*

Are you like me where bubbling water doesn't bother you but sputtering water and splashing does? I ask this because if you follow the instructions of this breeding box you'll hear loud, obnoxious sputtering. I'm not quite sure why it sputters the way it does, but it was driving me crazy. So this is what I did. In the instructions, you'll see two parts, Intake Tube (9) and Discharge Cap (8). Follow the instructions in putting the breeding box together, but then do the following if the sputtering noise bothers you like it did me. Throw out the Discharge cap. Feed a three inch or so piece of airline tubing into the top part of the Intake Tube where the Discharge cap would normally be affixed. Just feed it enough to be secure. Place the other end of the airline tubing into the water of the breeding box. You'll get bubbling instead of sputtering, which for me is realms more tolerable. Other than that this is a great little box. I use it as a half semi filter, half moss and shrimp storage. Edit: By the way, when you make the fix above, make sure the airline tubing you use isn't too long. Too long and the water struggles to make it up U turn of the Intake Tube, which causes it to act like just an airpump, instead of pulling water from the main tank in. If this happens and you don't realize it can be quite bad. For instance, if your house is cold and your tank warm, the pump won't bring the warm water from the main tank into the breeding box, so the temperature will drop heavily. That's bad. You'll also be dealing with only the water volume of the box instead of the water volume of the whole tank, which is also bad. So say you have this breeder box on a 10 or a 20 gallon, and you fix it incorrectly so that it's only bringing air into the box, then you've only got the water quality of the box, which is tiny. So make sure that both water is making it into the box and that water is exiting the box through the overflow (it should at least drip constantly).
