in-Tank Aquarium Breeder Box for Fish Tank, Breeding Incubator for Small Fish Hatchery, Acrylic Divider for Shrimp Clownfish Aggressive Fish Injur...

Came quick and was easy to set up

Very lame, small, cheap product. The suction cups have come off and its floated around the tank, the plastic cracked without ever being dropped or crushed. The V separater in the middle as well as the lid float, theres no clips or snaps to hold them in place, so I had to put a crunch of metal as a weight to keep the separater from floating and cannot submerge the tank or the lid floats away. The air bubbler is located at the top of the tank, so without being submerged that is useless too. The only thing that works is keeping my fish isolated, not even sure if the babies will fit through the V separater yet.. I didnt expect perfection, but I did expect it to work, considering it's only a few dollars cheaper than other brands.

Awesome little tank. No cracks or damage. Exactly what I was looking for. Suction is decent but I will probably add 2 more cups to the bottom to make it a little more stable. Packaging is definitely not very protective "Thin cardboard wrapped tightly around plastic tank and a very thin plastic bag) parts for tank loose inside banging around. I can see where some of the damage issues I see in reviews is a real possibility. Mine was perfect so Im happy. Just a observation that you're going to want to consider when buying.

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.

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.
