Fish Breeding Box, Acrylic Fish Isolation Box Aquarium Hatchery Incubator with Suction Cups for Newborn Fry Shrimp Guppy Clownfish Aggressive Fish, 11.5" x 6" x 6"

The media could not be loaded. This clear acrylic box works perfectly. Originally purchased for my betta, but the other fish had fry, so now it's a nursery (and the betta is enjoying the big tank much better). It arrived with one of the connecting arms broken so the rubber band won't stay put (pictured), but the box stays well put together with all other connection arms intact. It comes with 3 suction cups- I removed the 3rd one for an unobscured view, and it stay to the glass without slidding/detaching, even under the weight of rocks, and plants. It is just under 12 inches long by 6 inches tall, and 6 inches deep. You have to remove the frosted, plastic film from both** sides of every piece before assembling. Originally, I blocked the view of all other fish by simply cutting a white plastic folder divider (pictured), to size and slid it into place within the box. I then placed it over the air stone to provide oxygenated water to the fish, and also positioned it near the filter outflow so the water is constantly being renewed through the tiny holes in the sides. When divided into 3 compartments each one is just under 4 inces by 6 inches tall and 6 inches deep. Overall, I highly recommend this acrylic box. It works great, stays put, and is really spacious for your fishy friends♡

So far assembly was okay. Looks like it’s made in China but isn’t everything made in China? Like others have said, there could have been better instructions. If you’re a logical thinker, it’s easy to figure it out even with just the pictures provided. That one review that shows expectations vs reality, you can clearly see you didn’t peel off the plastic. Reality is reality, it’s clear. If yours look foggy it’s because you didn’t peel the plastic on both side. Mine came not broken, but I accidentally broke the lid hinge, but a little super glue makes it all good. Using this for a beta tank/display on my 50 gallon tank. Fits perfectly. Will update my review if it breaks. Might buy a second one for a second betta.

Its garbage. Doesn't snap or stay together. Cheap and flimsy. I had to put a big rubber band around it to keep it in 1 piece. Save your money.

I had originally planned for it to hang on the short side of my 29 gallon aquarium, but it was just short of being able to fit next to the filter I had, with the holes punched out of my top like so. I feel this is a very generic setup, so if it had just been a few mm skinnier it would have fit.The hooks that go over the lip of the aquarium are oversized, especially since they don't hold the weight of the box - the suction cups do that. Mine only rest on the inner edge. I anticipated needing to crack the lid a little bit, but the amount seems excessive. I understand it is designed for many tank types, but again, since I have a standard tank, it seems like a couple of mm could have been shaved off the top part of the hook, since again, this doesn't even really hold any weight.The dividers don't sit flush to the bottom of the box, so it should not be used to keep fry separate from one another. I used one section to make sure some otocinclus and pygmy corydoras acclimated to the tank so I could keep an eye on them, and since the corys were juvenile, they were close to being able to fit through, but didn't. It would work worry-free for larger fish.Assembly was easy... once the films were off. That is a huge pain and took 45 minutes just for that step between two people, and it was starting to wreck my thumb nail. Using a blow dryer to heat it up didn't help at all.From the description, I got the impression that the box would float depending on the level of the water, but that is not the case. You need to raise it to the actual level of your tank, and it does not move, so I can only take out 7.5 gallons of water for a water change rather than my usual 10, as it would bring the water level too low for any fish in there. I initially put it in too low, so a small fish was able to get into the box through the top feeding holes. It was kind of a pain to raise it up because you have to use a few tiny screws and washers, and retighten the suction cups. Because the suction cups are... suctioned, the box cannot slide back and forth along the tank if you are trying to get a hose around in the tank to suck up poop. Now that it is in, I have to basically stick my whole arm in the water to get to the filter sponge.I do love that it makes it easy to take photos of fish that are in the "naughty box" that need to find new homes. Again, it works great if you are aware of these design flaws, but it seemed so easy for them to be able to take these things into consideration that I had to rate it as such.

It seems like a quality box but we bought it for angel fish babies to keep them contained and they all escaped. The holes are just too big. We were so hopeful that it would contain them but it did not. The suction cups also did not stick for us. The hangers make it so our lid doesn't close. We will have to find an alternative.Adding for second experience. We put our momma swordtail in so she could give birth, which she did but the babies escaped. Only a few this time but they are squeezing through the dividers. I have the dividers in so that they don't escape the little slots where the dividers go. But they are squeezing between each of the three sections. Even a baby molly found it's way into the box. Two actually but I got one transferred back out.
