"Would buy again."

I also like to put in a bowl with acclimating. I got this so I can just put him in our 20-gallon hex with the angelfish. This product is good for the price. I've used several other floating breeders, and have always wished they were larger. So it IS possible for very small fry to slip through the slits. I didn't have the space for an external one. If that bottom piece fit better it would have been perfect.

"Imperfect design."

Less than 2 days and already received a replacement. I have two female Bettas and a Pleco in a filtered, heated 15-gallon tank. Not sure why some people are complaining the the separating tray floats. It's roomy and gives them space to move around. I feel like this breeder box is sturdier than some others that I've used.

"This product is great."

It comes with 2 removable dividers and a removable fry drop slotted piece. I also like to put in a bowl with acclimating. Suction cups do not hold the box up under its own weight. I do suggest leaving the lid above the waterline, however, as it has two holes. It would have been nice to have the suction cups. Mine's been doing fine and very useful. We picked this up to use as a secondary QT box for our reef tank.

"Just Kidding!"

It comes with 2 removable dividers and a removable fry drop slotted piece. The little air tube connection on the side is a nice addition too. Good quality and easy to take apart. There's only one issue with this unit. The seller, Pawfly, was very nice about it. The plastic is much thicker than the last box I bought for the same price. The net is harder to see through but not for the casual observer.

"Priced right."

There are slats in the bottom for the babies to escape to, to keep from being eaten. The funnel tray is placed too high within the box. I will definitely buy these kind of breeder again. Undeniably the best seller I've encountered. I'll put the bag from the pet shop in it and cut it open. I put the rainbar into it so now they can't escape.

"It is almost silent."

I also has a lid with snaps in place and has 2 slotted circles for dropping food in. I can home one day and one was dead and all torn up from the sides. I gave 4 stars becauses the mesh gets algae ridden pretty easily and stained green. The suction cups hold well, and it has floating handle chambers as a backup. I can home one day and one was dead and all torn up from the sides. I also like that it goes in to the tank and not a hang on the outside type. Still, everything else about the box is great!

"It's nice an big."

This works better at protecting babies from mom than the one room nets. I gave 4 stars becauses the mesh gets algae ridden pretty easily and stained green. For me, the geatest feature is that it floats and floats evenly. Mine's been doing fine and very useful. 5 gallon, but he was struggling to swim. We had 2 pregnant fish in seperate halves with them seperated. In the picture, the Petzilla Aquarium Fish Breeder box is on the right.

"Cheap but works good."

Two days later and we have about 20 babies swimming in the bottom part of the box. Tired of my guppies eating their fry and found this. We had 2 pregnant fish in seperate halves with them seperated. I usually wait to write reviews but I am already impressed with this breeding box. I tested both my tank and box water to find a big difference in Ammonia levels. 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.

"Keeps fish contained."

I am using several to sort through some fish I am breeding. I also has a lid with snaps in place and has 2 slotted circles for dropping food in. It's plastic but I have used it for several months and it’s help up well. I currently have about 30 or so new babies in it. This is the best floating breeder I have ever tried. The tube for the bubbler is a nice touch. Guppy fry didn't escape and they look happy.

"Works good."

Super strong suction cups- I have both the small and large. I use this all the time for fish or new plants. The lid doesn't lock in place too snugly which make it easy to open. I have used other breeder boxes and like this one the best. I own 7 of these isolation, breeding tanks. I'm using it as a nursery for baby guppies. Guppy fry didn't escape and they look happy.

"It was a great purchase!"

I have two female Bettas and a Pleco in a filtered, heated 15-gallon tank. Kind of a pain to remove the lid and feed the fry. We have 12 babies swimming around in our tank at the moment. The lid doesn't lock in place too snugly which make it easy to open. I didn't have the space for an external one. No more babies swimming back up the cracks and getten eaten by mom. Neither ended up having their babies in the breeder box.

I really like that it has suction cups, and is very sturdy on the glass. I do suggest leaving the lid above the waterline, however, as it has two holes.

"I'm happy with this."

Lets in just enough new water to keep it clean, but not too much to have a current. Not sure why some people are complaining the the separating tray floats. My kids observe the fish and write notes about health and behavior. Breeder nets are available in many sizes including larger than both boxes. The dividers only work with the fry drop in place. I have both the small and larger version. This product is excellent, works fabulously.

"Great product!"

Now he's chilling in quarantine until he heals. Definitely worth buying if you need to separate fish for any reason. I also has a lid with snaps in place and has 2 slotted circles for dropping food in. It's unsightly with big uneven seams and extra fabric. We picked this up to use as a secondary QT box for our reef tank. I also like that it goes in to the tank and not a hang on the outside type. Much easier to use and install than those tank partitions.

This works better at protecting babies from mom than the one room nets. Both are designed for free floating. She doesn't seem very stressed, honestly, and likes to nap in the V's.

"Only put about 30 gal."

I feel like this breeder box is sturdier than some others that I've used. The seller, Pawfly, was very nice about it. Two days later and we have about 20 babies swimming in the bottom part of the box. The seller, Pawfly, was very nice about it. Instead of catching babies, I simply leave the mom in the top piece. So it IS possible for very small fry to slip through the slits. I really like the design of this breeder box.

With the fry drop removed you get a really nice size little tank. So far, those have both held up, so the non-locking lid has not been an issue. I also like to put in a bowl with acclimating.
