"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.

Saim E4YKSZ09523 First Impressions

"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!

"He's about 3."

The plastic is much thicker than the last box I bought for the same price. Suction cups do not hold the box up under its own weight. Hope you found this review helpful! The dimensions for the large size are approximately 8. This works better at protecting babies from mom than the one room nets. I have used other breeder boxes and like this one the best. We picked this up to use as a secondary QT box for our reef tank.

"My own dumb fault."

You have to be really careful with shrimp or they die. In the picture, the Petzilla Aquarium Fish Breeder box is on the right. The suction cups hold well, and it has floating handle chambers as a backup. Both are designed for free floating. This product is excellent, works fabulously. My husband got me a few guppies that apparently had been pregnant. It's a decent size for an internal breeder box.

"Overall I did like it."

I do suggest leaving the lid above the waterline, however, as it has two holes. I tested both my tank and box water to find a big difference in Ammonia levels. This is my first breeder box so I cant really compare with other brands. I currently have about 30 or so new babies in it. First one arrived used with gravel and a hole in it. They are now all back together, living as peaceably as fish can. I put three pregnant females in the box immediately.

"Over all pretty good."

They are now all back together, living as peaceably as fish can. Apparently my purple Betta, Dragonfruit, did not get the memo. The breeder box has a decent size for isolating fish or dwarf shrimp. I will update after the babies are born but so far this is great. Worked well, water and air flow is minimum due to slots being very thin. I am using several to sort through some fish I am breeding. The Petzilla and Lee's make observations easier.

"Would highly recommend."

I currently have about 30 or so new babies in it. Fits nicely in a size 10 gallon tank. My kids observe the fish and write notes about health and behavior. It works as it is designed to do and kept my fry safe. I have used other breeder boxes and like this one the best. The net is harder to see through but not for the casual observer. I left it out and the babies were sneaking out through that hole.

"Great product!"

This keeps her area better airated and actually helps flow the babies out. It's unsightly with big uneven seams and extra fabric. I use this all the time for fish or new plants. I also has a lid with snaps in place and has 2 slotted circles for dropping food in. My other one was fine but I brought her out so she wouldn't get hurt. I have noticed that with all they pieces in that food does not exit the bottom half. It would have been nice to have the suction cups.

Less than 2 days and already received a replacement. I don't see how they send used stuff out as new! It's unsightly with big uneven seams and extra fabric. I have both the small and larger version.

This keeps her area better airated and actually helps flow the babies out. I never knew how important this was until tank cleaning time! The dividers only work with the fry drop in place.

"Works really well."

Future design improvement- less room for fry, more room for moms. With the pump it's completely circulated and levels are normal. I actually put it in my 10 gallon baby fry tank. My other one was fine but I brought her out so she wouldn't get hurt. 5 gallon, but he was struggling to swim. I own 7 of these isolation, breeding tanks. She doesn't seem very stressed, honestly, and likes to nap in the V's.

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

Unlike the males, female Bettas should get along together. Good size and I like the separated chambers. I feel like this breeder box is sturdier than some others that I've used. I put the rainbar into it so now they can't escape. Guppy fry didn't escape and they look happy. With the fry drop in you have plenty of room for temporarily keeping the females. I have two female Bettas and a Pleco in a filtered, heated 15-gallon tank.

I tested both my tank and box water to find a big difference in Ammonia levels. I will update after the babies are born but so far this is great. I use this all the time for fish or new plants. It works as it is designed to do and kept my fry safe. Two days later and we have about 20 babies swimming in the bottom part of the box. Not as sturdy as I thought but perfect for what I wanted. Each of the four corners I thought had a cap.

Flameer First Impressions

"It's sturdy so far."

I highly recommend this product, simple and easy to use! I bought one to try it out, and it's been excellent. This is my first breeder box so I cant really compare with other brands. So it IS possible for very small fry to slip through the slits. Not sure why some people are complaining the the separating tray floats. With the fry drop in you have plenty of room for temporarily keeping the females. I've used several other floating breeders, and have always wished they were larger.

I have noticed that with all they pieces in that food does not exit the bottom half.
