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

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♡

Wow! More than I expected. It's a huge size with 3 components. Easy to install and it's stable. Suction cups are great and hold a very tight grip even though my tank was full. I did not needed to install the hooks. I am truly impressed with this product and highly recommend it.

Two and a half months since I bought this, used once for a few days. Yesterday was trying to set it up again - the little plastic screws falling apart, breaking, one of the hinges broke where it screws into the main box. Not a bad design, garbage quality and waste of money on my end.

I love this box. It was easy to assemble. It is made out of good quality plastic. I can place it on the gravel or hang it from the side of my half-circle tank. I bought this to protect the small new residents in my semi-aggressive tank with Oscars and plecos. I can see them and they are protected. The holes are the right size and allow for regular water flow, so while they grow, they are already acclimated to their home tank conditions. If I wanted to separate specimens I can just slip the dividers in and have up to three separate compartments. Here is the one fatal flaw that is easily addressed. The lid has larger holes. This is likely to facilitate feeding without opening the lid. This is no problem if your protected guys are large enough. If not they will swim through and disappear. It was a purchase of two small dinosaur bichirs that prompted this purchase. I hanged the box with all sides submerged. One day, I noticed an MIA. Sometimes, I am a bit slow, so the next day, I looked and the box was empty. Bichirs of any variety are usually hard to find, but a local PetSmart had some so I could start again and this time with the lid about an inch from the water surface. I do not use the suction cups, but after losing the first two bichirs, I attached them. The holes for them are big enough to let little guys out. The suction cups do not impede or spoil the view. The box is a very functional, attractive accessory. I feel the value will outperform the price point.

I know there are some caveats to this product but for the price, it's worth it. I've spent more than that on crappy breeding nets with flimsy tank hooks that break if you sneeze and that I've had to jerryrig it back to working condition with twist ties. This product is none of that. It is sturdy and beautiful. And, I can see my babies! Quite frankly, it doesn't need the hooks since the water level usually never gets low enough to use it and the suction cups work great, so I may end up just removing them. I'm not quite sure if you can see the suction cups but it's not those simple ones that lose hold after some time. They are the screw nut suction cups. Since there are 3 and strategically positioned, the box stays put. Yes, you do have to put your hand in the water to adjust the box/suction cups as the water level falls. When I clean my tank, I move it to as low as it can go without my babies swimming out. And then as I put water back in, I move it back up. This is much better than the net breeders where I can't adjust the height at all and have to move my babies out to clean the tank. You might not be able to see it from the picture, but I removed the walls so the automatic feeder feed all the babies when I was away on vacation. Luckily, I didn't have big mommies that would eat their babies so it worked out. One last note, the lid works for keeping large fish in but there's a gap when under water, so if you are keeping babies, the top of the box has to always be above water level. One thing that I do wish it had is that little grill and space for the babies to go through so the mommas don't eat their own before I can fish them out. Not a ding on this box since most other boxes are the same but it would be a great option to have so that once the momma is moved to another compartment to rest, the grill can be removed and the babies have space to swim.

Pro: Good packaging, easy to assemble, hangs on the back of the tank well, good for separating fish from main tank mates, big suction cups, and nice opening at the top for feeding. Cons: The lids connecting the lip are small and flimsy, mine broke off, and the lid doesn't have a good seal (See picture), not good for Fry, Suction cups are not good. Overall: Decent product better than the netted breeder box, the lid needs some work to keep the Seal. I would recommend this product to others. Please review my pictures to give you a better picture of the seal between the box and the lid.

Perfect for breeding snails or shrimp within a puffer tank. Capped at about 3-4 for neocaridinas, or you can have 40 small ramshorn snails in there. There’s very little flow though, and so if you put fish in it, you should add an oxygen tube.

Really durable material and easy almost no instructions required construction. Fits almost hand-sized fish just fine.
