High quality build. Like the fact that the box is inside the tank verses outside. Unique design.

This breeder box is absolutely designed very well. Its easy to clean and water flow is amazing. Never have to worrie about any sort of spikes of ammonia when leaving small aglie waffers for my baby corys overnight. I constantly kept having loss of baby corys in other breeder boxes. Not one with the the Ziss Breeder Box. This is the absolutely the best and Would recommend to anyone looking for safe and more modern way to raise baby fry!

After seeing the corys being frisky, we thought the well constructed breeding box was needed. 1F 2M in there. We'll they like swimming & playing around in it. So after our 2M 1 female, she dropped eggs after breeding in the breeder box. After an hour, we let them back in tank, and ohhh my. The female went thru about 15 egg placements & I was there to try and retrieve. This breeder box far exceeded out local fish BB. I hope we get some fry! Our Cory's were in the mood!❤️

Something happened to my new shrimp tank and I had to take it down. Thankfully, I had the Zeiss breeder box so they can safely be in the tiger barb tank while I restart the cycle in their tank.

The Ziss Breeder Box really has really unlocked another level of the hobby for me. I was able to harvest eggs and safely raise some panda cory fry for my husband's new tank when he FINALLY caught the fish-keeping bug. Allowed me to raise the fry in the stable water conditions of my seasoned, planted 65 gallon tank. The reinforced bottom makes it so the big fish can boop the bottom of the box without disturbing the fry. Sturdier than the net breeder BY FAR- worth the extra cost.

This breeder box is amazing! My very first time ever breeding fish and I started with 23 Betta fry. At around 2 weeks old I started having some die and ordered this breeder box to be able to filter the water better with a power filter with them safely inside. Not a single loss since putting the remaining 16 fry in this box and they are now 1 month old.

Awesome product, successfully hatched my first corydoras inside the box and now raising the fry.

I have had minimal luck raising my bronze Corydora babies without them dying. As you can see, my babies are doing very well from this new batch. I had 13 eggs and I have six little ones doing very well and I have to contribute that to the breeder box!

This is the best breeder box I try love it keep baby fish away from adults fish it stay in place. I try the mesh box from PetSmart and it always fall in the water and baby fish find there way to under the mesh unable come back out.

I love this breeder box! I am raising Australian Rainbow fish, which are incredibly tiny when they hatch. They are much bigger now that they are a month old. I modified my box to ensure the fry would not escape through the water inlet slits. It is quick, simple yet effective: I cut a piece of thin foam to fit between the air tubing and the inlet slits.

Five day old platy fry doing alright! This is probably the only BEST breeder box on the market.. won't let your fry escape or get stuck in a cheap net...

Great product. Didn’t come with assembly instructions but it was pretty easy to figure out so that wasn’t really an issue.
It gives a really nice flow for the fry which I really like because in my experience fry grow a lot quicker when there’s good flow provided. It’s a perfect size and super clear in the front so you can see all your fry, which is nice because the net trap I had before was nearly impossible to see the fry, and even harder to see when I fed microworms and vinegar eels, which now I can see clear as day!
What else is super nice is that it gives room for the adult fish to swim in front of it without getting stuck, which with the net trap they’d get stuck, and with the plastic ones the fish really get stuck, and unfortunately have accidentally killed a fish putting it in a tank before 😬well, it didn’t kill the fish but it pushed the insides out and ended up having to euthanize the poor thing. Luckily that’s not an issue at all with this one!
It also comes with a lid so no big fish can hop in.
I can definitely say it was worth the money. And it doesn’t look ghetto in the fish tank where the plastic and net ones look kinda ghetto.

Good product. Came fast and the best price around

I’m so happy I found this breeder box, it’s a nice size and it’s really sturdy. I’m currently using it to house my tiny cherry shrimp so they can give birth peacefully. 10/10 !

Works Perfect the suction cups actually stick amazing product

This is such a perfect amazing product at a great price that I can't say enough good things. Normally I am a DIY type, but this is such a great product I could not improve on it, and could barely do it cheaper. It maintains constant water flow, leading to excellent fry health, and is easy to use, secure, and stable. I am convinced that this is directly responsible for my sucess with a recent unexpected cichlid spawn. Aquarium Co-op got it to me super fast, and I was able to pull the eggs just as they were beginning to hatch.

I've used the floating plastic boxes, hang-on net boxes, and Marina air driven boxes and the Ziss Ez breeder takes the win. You get the continuous aeration and water movement of the Marina box along with the benefit of being able to hang it inside and aquarium with a closed lid (which is great if you want to minimize evaporation).

Easy assembly, easy/convenient use, and so far easy maintainability make this product a win in my book!

This box made my whole life easier. Just connect it to an air line and forget about water changes. All the leftovers and brine shrimp eggshells fall off the bottom keeping the chamber nice and clean. Lovely, good quality, my fishies were safe at all times! The only thing I did just to be even safer was to add a little piece of foam at the top where the water comes in the chamber, just to block any fishy getting stuck in there. BUT I LOVE it. It’s worth having it. Very satisfied.

Amazing little breeder! I set it up for my guppy mom who looks like she is in a deluxe birthing resort!
