Aquarium Fish Breeder Box - Hatching & Spawning Incubator, Water Isolation Net Hatchery

Great for separating the problem from your tank put them in timeout for a couple days and u drop In a new fish

This breeding box is larger than most, which is perfect for my African cichlids. The net fits well and is strong enough while still being sheer enough for the fish to see each other and water to pass through easily. My only complaint, and reason for not giving five stars, is that the green supports easily fall out of their keepers. I'm constantly needing to push the supports back together while there are fish in the box, which is difficult.

It was bigger than I was imagining, but it worked for what I wanted. I needed something to put my betta fish in to get him used to being in a tank with other fish. I didn't need him going straight into bully/predator mode. It did the trick!

Lacked any semblance of thorough directions as photo shows. Quite a few steps are not included so I did a video and hopefully it’s helpful. I used my pea brain to figure it out. Okay, so really, it’s about a five dollar product. It does the trick, though, or at least it did for me. As far as I know, it worked flawlessly and no free fry snacks for dear ol’ mother dear. The next day after I put my female Molly in, I spotted tiny fry resting on the mesh. Maybe that isolation made Mommy just comfy enough to let some babies drop. The fry were tired initially and stayed on the bottom but can and did easily come back up through the grate divider. The grate is ginormous compared to most breeder boxes but it does provide some protection as long as the fry don’t venture upwards. But, logically, any gap big enough for fry to go through will also allow them to go back with mom. It’s main function is to provide a barrier for mom. Thankfully, I had already removed Ma Cannibal and had no issues. Important notes: During assembly, make sure the knobs on both pieces of the frame are both on the same side unless you like one set of suction cups to face the wrong direction. Also, the grate (fry trap?) has a slot to insert the divider if you want to separate two adult fish. Make sure that slot faces up or you will not be able to install the divider without taking most everything apart. I was lucky and did it right the first time. Also, the suction cups attach over the netting. I have had no issues with this product other than the mesh pulling away from the elastic. For this reason, I did order a replacement and it came right away. Anyway, hope you enjoy my video and found my review helpful. And may every day be a happy Fry-day!

Very cheaply made product. The legs barely stay in their holes. Would not recommend this product.

I'm a member of a tropical fish club and recently started breeding rainbowfish. The fry are tiny and spend their first weeks in a "German breeding ring". But once they get to about half an inch long, they needed more room. but can't be set loose in a big tank or they'll be outcompeted for food. I ordered this, and it works far better than I thought. Very easy to assemble. Just to be on the safe side, I used a drop of super glue (which is aquarium safe) on each piece when assembling. The suction cups are very strong and haven't budged from the sides of my 50 gallon tank. The fry are happy, have lots of room to swim (this net box is BIG!) and the netting is small enough they do not get stuck in it or even try to go through the holes. I think this will last through many batches of fry.

He's about 3.5 inches long and fits great. This was easy to assemble -- it took about two minutes. I installed it perfectly at the top of the tank in one shot. The image shows it in a 75 gal tank. Great purchase!

Pretty good product, however the base came a little noticeably bent and was a bit of a problem when setting up. The net was a hassle to get on because of how tight it is, but didn’t take more than 5 minutes to assemble! Make sure you pull this thing up, the first thing my girl did was swim right back in with the rest of her tank mates. I would imagine for my bigger 6” cichlids, the bottom part would need to be removed, but for her size (around 2-3”) works great.
