The Fluval Multi-Chamber Holding & 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.

Customers say
Customers find the breeder box works well and is easy to set up and use, considering it worth the price. The size receives mixed feedback – while some find it good for refugiums, others say it’s too large. The build quality, water flow, and noise level also get mixed reviews, with some finding it well-made while others report cracks upon arrival, and while some appreciate the increased water flow, others note it’s not great.

Works well.
Works great. Working outside the tank but drawing water from inside saves space and helps to acclimate fish to your tank as the input of water can be adjusted with a flow adjusting valve on your air line.

Works well and super cute
I love this box! It looks so much better than the mesh ones I had before. I like that it provides a separator for the mom and the fry. It has a leveling tool so you can make sure the box is sturdy and perpendicular to the tank, which I thought was pretty cool. I like that it also has a slot to cover the outlet to try to prevent fry from getting flushed back into the tank

Put the cap on the end of the inside of the intake tube!!!
It came with no instructions, but it was pretty easy to figure out. The only thing I had trouble with trying to figure out is those two tabs that go underneath where it hooks onto the tank as seen in the photo I took in between the tank and the box underneath. Still don’t fully understand the purpose of those two tabs. But it’s whatever it may be. Right now it’s on the back of a 29 gallon. It’s a great box to breed fish in, put their eggs in, act as a holding tank, or even use as a specimen container if ur looking to sell fish or examine them! And if ur wondering what those two little rubber things are, they’re the clips to hold the top down if u have any aquatic friends that like to jump or escape. I see a lot of people say they have gargling or sputtering issues with the set, but mine came with a cap the has another hole on the side and I just put it on there end of the intake tube on the inside and it’s as silent as can be. At least for my ears. So if urs came with a clear cap that has a hole on the side of it, stick it in there and see what it does for urs. So for the lack of instructions for everything that come with it, i give it 4 out of 5. Otherwise if it had instructions to come with it, i give it 5 out of 5! Great box!!! Definitely recommend! Oh! The air pump I have that’s running it is a 3W 2 outlet adjustable air pump for the stone and the intake. Works really good! Good flow! The 2 air flow control valves, the 2 check valves, and the stone with the suction cup all came with the air pump I ordered separately with this. The purple artificial plants I ordered separately as well. I figured it’d be good to put those in to help them feel safer and hopefully be able to see them better as they move around. Also provide more surface for bio film and beneficial bacteria to grow on. I would’ve put real plants in but hornwort tends to grow pretty fast and it’s hard to see those little white babies swim around in them. Hah So I put a small dwarf water lettuce in there instead to see how it goes. But anyways, hopefully this review will help those who are thinking about getting one of these. In my personal opinion, don’t hesitate to get this because it’s so versatile and u can use it for so many things other than just breeding. It’s a great thing to have in ur arsenal as a fish keeper/breeder and I think everybody should have them especially if they’re just starting out in the hobby. Have a nice day!!

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!

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.

Excelente para su propósito. Cuando los alevines crecieron le instalé una bomba de agua, lo llené de piedra volcánica y plantas y lo uso como un filtro de mochila auxiliar.10 de 10
