in-Tank Aquarium Breeder Box for Fish Tank, Breeding Incubator for Small Fish Hatchery, Acrylic Divider for Shrimp Clownfish Aggressive Fish Injured Fish, Can Connect Air Pump (Small)

Size is acceptable to be called large. Arrived quickly. Removeable fry funnel is nice. Only complaint I have is the suction cups could be better. They released from the tank glass spilling segregated fry into the main tank to be deviured by much larger African Cichlids. Very disappointing..

Like most of the reviews here, the suction cups suck #^@ that come w this. But thankfully I had some of these twist suction cups lying around from a product I no longer wish to use.But add two of these and you got a pretty banging product w no issues at a decent price. But you will need to melt the holes bigger, drilling will crack. I juat used the back end of a heated bit to get it right.PSA / BTW, for the ppl complaining about the nick in the air line piece... that by fracking design 🤣🤦‍♂️

The box is great. The space is great, the suction cups…. Not great. Will need to figure out a way to help it stick.

Here's my so-so experience with the Petzilla Breeder Box after 4 months...-Suction cups come loose from glass quite often (other brand never did that). This results in fry escaping into main tank, and adult fish entering box and feasting on the fry. And no, I didn't have the lid on. Maybe that would've prevented it, maybe not.-Lid sticks...a giant pain at feeding time. Hard to remove lid without having to stick fingers in tank and really work it loose. Holes are difficult to fit food through. Can be done, need good aim. Used w/o lid.-The 3 corner tubes that are "closed" will allow fry to rest on them. Fine unless the water level gets too low. On occasion my fry got stuck on top of the tubes and became fish out of water and didn't survive.-The open corner tube used for aeration...I chose not to connect an air supply, thus the fish swim down into the tube. Fine if water level is above the rim, but if it lowers, fry get stuck in the tube and can asphyxiate...as mine did. Also, food and debris accumulates in that tube.-Tabs that connect top and bottom half are VERY difficult to open. In fact, required a knife point to seperate tab, and takes lotsa shimmying to seperate top and bottom half. Ironically, one tab broke recently from using thumb pressure, not the knife.-If you "pour" the fry into another container to clean tank or box, the fry get stuck between lip b/t top and bottom half AND stuck in the tubes! PANIC mode sets it...Then you try to get the tabs loose to separate and you can't....you end up w/fish out of water, fish stuck, stressful for the fish AND you.-Tray that separates mom and fry...hard to get to stay in place. Once you do it works nicely. Fry drop down and mom is seperate. However, once mom removed, and you want to remove tray...GL! You'll need to seperate the top and bottom halves to remove and that is a challenge.Overall, it's merely a fair product.

Good structure and size for the money. Improvements needed for suction cup material. After being in the water for a while cups degrade by inverting and no longer hold suction.

Ive used this breeder several times and do like it but it has a 15/20% mortality rate. Everytime I wake up to babies several are dead and stuck in the tiny slits.

I tried putting my pregnant swordfish in it but she stayed stressed and I had to take her out. The lid falls off and the two holes on the lid were big enough for other fish to get in and her to get out although she never found the hole to swim out. Maybe it would work for a guppie or something very small. I am going to get another tank to separate any fish. I wouldn't recommend spending money on this. It is to hard on the fish in such a small space. I am going to get me a 30 or 40 gal. tank or put a divider in my 100 gal. Any fish other than guppies or smaller fish get to stressed out. My pregnant swordtail actually lost weight being in there and as soon as I put her back in my main tank she put her weight back on. Even a 10 gal would be better than this. This is just my opinion, you make like it. Please just don't put anything but really small fish and even with that u could only put one guppie.

I really like this fish breeder. It is large enough for fish bigger than guppies. Easily accommodates two Molly's, swords or platy fish. The little air tube connection on the side is a nice addition too.It is a bit difficult to disconnect the bottom from the top, but I have had others that came apart too easily, so this is better. It is also a bit tricky to set the divider in place that keeps the babies below, but not hard.I have found one very unique use for it though. I actually put it in my 10 gallon baby fry tank. I simply took off the bottom of it, below the divider that allows the baby fry through and keeps the mom out. Instead of catching babies, I simply leave the mom in the top piece. The babies fall through the cracks like they are supposed to, but they fall right into the baby tank. It is awesome! No trying to get mom back out while trying to keep babies in. No more babies swimming back up the cracks and getten eaten by mom.I also run an air tube in the air hole / pipe. That way the water still flows nicely in where mom is. This keeps her area better airated and actually helps flow the babies out.After the mom is finished having the fry I just pull out the entire box and move her back to the community tank.The only problem that I have run into is that the suction cups sit too far in and behind. They are impossible to reach once it it attached.

Bel incubateur double pour petite poissons .. Avec petite tube pour brancher une pompe a air.. Parfait pour faire accoucher mes femelles guppys en toute sécurité ..

Works great. Suction cups seem to hold pretty good except for once when it wasn't on a very clean spot. Other than that I have to put something between them and the glass to get it to pop off. The lid could fit a little tighter though.Edit - dropped to 3 stars now because after a week one suction cup came loose. One locking tab for the bottom section broke off as well. The design is great but could be made a little better.

Il faut savoir il ya des ouverture alors ce n'est pas fait pour isolé un poisson malade, je l'utilise pour isolé mon betta des autres poisson une ou deux semaines par mois il adore avoir son indépendance lorsqu'il est libre je laisse là boite dans l'aquarium et tous peuvent l'utiliser
