"The thing is awesome!"So it IS possible for very small fry to slip through the slits. Instead of catching babies, I simply leave the mom in the top piece. I have used other breeder boxes and like this one the best. Not as sturdy as I thought but perfect for what I wanted. With the fry drop removed you get a really nice size little tank. Worked great for me and my need to separate babies from the rest of the tank. Tired of my guppies eating their fry and found this.

Penn-Plax AN2 Final Thoughts
"He's happy, so I'm happy."Unlike the males, female Bettas should get along together. Easily accommodates two Molly's, swords or platy fish. They seemed scared at first but calmed down after about 30 minutes. Especially if you plan to hold the babies there for a while. Kind of a pain to remove the lid and feed the fry. I put three pregnant females in the box immediately. Suction cups do not hold the box up under its own weight.

"Great purchase!"My husband got me a few guppies that apparently had been pregnant. This is my first breeder box so I cant really compare with other brands. I ordered this and it came next day. Tired of my guppies eating their fry and found this. I put the rainbar into it so now they can't escape. Instead of catching babies, I simply leave the mom in the top piece. I really liked the fact I could add an airline for water flow.

"I really like it."It is large enough for fish bigger than guppies. The lid doesn't lock in place too snugly which make it easy to open. So it IS possible for very small fry to slip through the slits. This product is excellent, works fabulously. I bought one to try it out, and it's been excellent. I will definitely buy these kind of breeder again. I will update after the babies are born but so far this is great.

"They held water well."I really like that it has suction cups, and is very sturdy on the glass. It is large enough for fish bigger than guppies. Much easier to use and install than those tank partitions. I am using several to sort through some fish I am breeding. I have noticed that with all they pieces in that food does not exit the bottom half. I have two female Bettas and a Pleco in a filtered, heated 15-gallon tank. I've used several other floating breeders, and have always wished they were larger.

"It's sturdy so far."We picked this up to use as a secondary QT box for our reef tank. So far, those have both held up, so the non-locking lid has not been an issue. My kids observe the fish and write notes about health and behavior. This product is good for the price. This keeps her area better airated and actually helps flow the babies out. I use this all the time for fish or new plants. The dimensions for the large size are approximately 8.

"Very useful."We had 2 pregnant fish in seperate halves with them seperated. The breeder box has a decent size for isolating fish or dwarf shrimp. With the fry drop removed you get a really nice size little tank. No more babies swimming back up the cracks and getten eaten by mom. So overall, this is a functioning product with little issues. I left it out and the babies were sneaking out through that hole. I do suggest leaving the lid above the waterline, however, as it has two holes.

"I liked this breeder box."The breeder box has a decent size for isolating fish or dwarf shrimp. I took the out of the tank and put them in mugs but it was not practical. The little air tube connection on the side is a nice addition too. With the pump it's completely circulated and levels are normal. The net is harder to see through but not for the casual observer. I really like the design of this breeder box. The baby fish were able to swim from the bottom back to the time in the corners.

"Great product!"I own 7 of these isolation, breeding tanks. I don't see how they send used stuff out as new! I really like that it has suction cups, and is very sturdy on the glass. You have to be really careful with shrimp or they die. Especially if you plan to hold the babies there for a while. I also has a lid with snaps in place and has 2 slotted circles for dropping food in. I use this all the time for fish or new plants.

Alfie First Impressions
"I would buy again!"The Petzilla and Lee's make observations easier. They seemed scared at first but calmed down after about 30 minutes. Good quality and easy to take apart. The tube for the bubbler is a nice touch. My other one was fine but I brought her out so she wouldn't get hurt. She doesn't seem very stressed, honestly, and likes to nap in the V's. If you have a smaller tank, the Lee's may be the better choice.

"Arrived on time."I really liked the fact I could add an airline for water flow. We did have some get stuck in the edge of the partition. You have to be really careful with shrimp or they die. Lets in just enough new water to keep it clean, but not too much to have a current. The net is harder to see through but not for the casual observer. I had a 2 pregnant guppies and bought this for them. We need to do mare to make sure bettas are treated better in pet stores, though.

"Awesome product."I'll put the bag from the pet shop in it and cut it open. Petzilla is larger in size which reduces crowding as the babies grow. Not sure why some people are complaining the the separating tray floats. First one arrived used with gravel and a hole in it. This is my first breeder box so I cant really compare with other brands. They seemed scared at first but calmed down after about 30 minutes. Both are designed for free floating.

"Great external refugium."Hope you found this review helpful! So overall, this is a functioning product with little issues. This works better at protecting babies from mom than the one room nets. It comes with 2 removable dividers and a removable fry drop slotted piece. With the fry drop in you have plenty of room for temporarily keeping the females. As with many plastics, if it isn't thick enough, then it can break. Suction cups do not hold the box up under its own weight.
