"I'm happy with this."

Much easier to use and install than those tank partitions. I have both the small and larger version. I will update after the babies are born but so far this is great. There's only one issue with this unit. We have 12 babies swimming around in our tank at the moment. We picked this up to use as a secondary QT box for our reef tank. Took me a little while to figure it out but it worked for me.

"So this is what I did."

If you have a smaller tank, the Lee's may be the better choice. Now he's chilling in quarantine until he heals. I also like that it goes in to the tank and not a hang on the outside type. There's only one issue with this unit. It is large enough for fish bigger than guppies. With the fry drop removed you get a really nice size little tank. I put three pregnant females in the box immediately.

"This product is great."

When I came across this one that showed the actual inner dimensions, I was impressed. This works better at protecting babies from mom than the one room nets. We need to do mare to make sure bettas are treated better in pet stores, though. It's unsightly with big uneven seams and extra fabric. He had room to still swim around and I didn't feel too guilty. Undeniably the best seller I've encountered. This product is good for the price.

"Mines in the mail ."

Perfect for holding my guppy babies. This is the best floating breeder I have ever tried. I didn't have the space for an external one. The dimensions for the large size are approximately 8. I tested both my tank and box water to find a big difference in Ammonia levels. We have 12 babies swimming around in our tank at the moment. I have safe little fry and more to come!

"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.

"He's happy, so I'm happy."

No more babies swimming back up the cracks and getten eaten by mom. I personally use these to introduce smaller fish into my community tanks. Fits nicely in a size 10 gallon tank. My other one was fine but I brought her out so she wouldn't get hurt. If that bottom piece fit better it would have been perfect. I didn't have the space for an external one. If you have a smaller tank, the Lee's may be the better choice.

"I really like it."

We need to do mare to make sure bettas are treated better in pet stores, though. She doesn't seem very stressed, honestly, and likes to nap in the V's. We have 12 babies swimming around in our tank at the moment. Apparently my purple Betta, Dragonfruit, did not get the memo.

"Great item!"

Petzilla is larger in size which reduces crowding as the babies grow. Guppy fry didn't escape and they look happy. I will update after the babies are born but so far this is great. No trying to get mom back out while trying to keep babies in. You have to be really careful with shrimp or they die. I'm using it as a nursery for baby guppies. The funnel tray is placed too high within the box.

"No, really, I'm kidding."

Much easier to use and install than those tank partitions. Still, everything else about the box is great! This is the best floating breeder I have ever tried. Two days later and we have about 20 babies swimming in the bottom part of the box. I really like that it has suction cups, and is very sturdy on the glass.

"Two thumbs up."

My kids observe the fish and write notes about health and behavior. I own 7 of these isolation, breeding tanks. Neither ended up having their babies in the breeder box. Future design improvement- less room for fry, more room for moms. My kids observe the fish and write notes about health and behavior. I really like the design of this breeder box.

I have safe little fry and more to come! Not sure why some people are complaining the the separating tray floats. With everything out the tank seems to stay really clean.

"Glad I bought this."

Hope you found this review helpful! With the fry drop removed you get a really nice size little tank. Still, everything else about the box is great! Mine's been doing fine and very useful. I rated this 4 because it works great for the babies to live in for a bit. I took out the part that separates the parent from the babies. My husband got me a few guppies that apparently had been pregnant.

"It is perfect!"

Took me a little while to figure it out but it worked for me. The funnel tray is placed too high within the box. Definitely worth buying if you need to separate fish for any reason. It's a decent size for an internal breeder box. Easily accommodates two Molly's, swords or platy fish. So overall, this is a functioning product with little issues. We picked this up to use as a secondary QT box for our reef tank.

"The large is VERY SMALL."

It's plastic but I have used it for several months and it’s help up well. I took the out of the tank and put them in mugs but it was not practical. When I came across this one that showed the actual inner dimensions, I was impressed. As with many plastics, if it isn't thick enough, then it can break. I have two female Bettas and a Pleco in a filtered, heated 15-gallon tank. I do suggest leaving the lid above the waterline, however, as it has two holes. No trying to get mom back out while trying to keep babies in.

"Tried him in a 3."

Less than 2 days and already received a replacement. This keeps her area better airated and actually helps flow the babies out. The Petzilla and Lee's make observations easier. I put three pregnant females in the box immediately. I also like to put in a bowl with acclimating. The breeder box has a decent size for isolating fish or dwarf shrimp. Both are designed for free floating.

"Overall I did like it."

I don't see how they send used stuff out as new! Good size and I like the separated chambers. We have 12 babies swimming around in our tank at the moment. She doesn't seem very stressed, honestly, and likes to nap in the V's. The little air tube connection on the side is a nice addition too. Tired of my guppies eating their fry and found this. We did have some get stuck in the edge of the partition.
