"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.

Sera 8584 Final Thoughts

"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. I feel like this breeder box is sturdier than some others that I've used. We had 2 pregnant fish in seperate halves with them seperated.

She-love First Impressions

"I recommend this box."

For me, the geatest feature is that it floats and floats evenly. Hope you found this review helpful! The plastic is much thicker than the last box I bought for the same price. I tested both my tank and box water to find a big difference in Ammonia levels. My kids observe the fish and write notes about health and behavior. The suction cups hold well, and it has floating handle chambers as a backup. No trying to get mom back out while trying to keep babies in.

She-love Final Thoughts

"Assembly was fine."

I will update after the babies are born but so far this is great. I tested both my tank and box water to find a big difference in Ammonia levels. So it IS possible for very small fry to slip through the slits. When I came across this one that showed the actual inner dimensions, I was impressed. I ordered this product for my Balloon mollie babies. I have noticed that with all they pieces in that food does not exit the bottom half. It's a decent size for an internal breeder box.

"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.

San Francisco Bay Brand 9012 Final Thoughts

"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!

"Glad I bought this."

It is large enough for fish bigger than guppies. 5 gallon, but he was struggling to swim. She doesn't seem very stressed, honestly, and likes to nap in the V's. So it IS possible for very small fry to slip through the slits. Worked well, water and air flow is minimum due to slots being very thin. I personally use these to introduce smaller fish into my community tanks. Not as sturdy as I thought but perfect for what I wanted.

"Clear plastic EZ to use."

It's unsightly with big uneven seams and extra fabric. Unlike the males, female Bettas should get along together. I took the out of the tank and put them in mugs but it was not practical. Not as sturdy as I thought but perfect for what I wanted. I left it out and the babies were sneaking out through that hole. I popped this together in a minute and it was in the tank in another minute. Both are designed for free floating.

I have found one very unique use for it though. I really liked the fact I could add an airline for water flow. That's why I took time to come back. I will definitely buy these kind of breeder again.

PIVBY Final Thoughts

"This is not a small box."

It comes with 2 removable dividers and a removable fry drop slotted piece. Instead of catching babies, I simply leave the mom in the top piece. I will update after the babies are born but so far this is great. I'm using it as a nursery for baby guppies. I've used several other floating breeders, and have always wished they were larger. I currently have about 30 or so new babies in it. Two days later and we have about 20 babies swimming in the bottom part of the box.

"Suction cups are good."

The tube for the bubbler is a nice touch. It's unsightly with big uneven seams and extra fabric. The net is harder to see through but not for the casual observer. With the fry drop removed you get a really nice size little tank. I bought one to try it out, and it's been excellent. That's why I took time to come back. The Petzilla and Lee's make observations easier.

"Priced right."

Suction cups do not hold the box up under its own weight. This is my first breeder box so I cant really compare with other brands. I usually wait to write reviews but I am already impressed with this breeding box. I personally use these to introduce smaller fish into my community tanks. I have both the small and larger version. The little air tube connection on the side is a nice addition too. I got this so I can just put him in our 20-gallon hex with the angelfish.

"Thank you so much!"

I put the rainbar into it so now they can't escape. Apparently my purple Betta, Dragonfruit, did not get the memo. I will definitely buy these kind of breeder again. I never knew how important this was until tank cleaning time! This is the best floating breeder I have ever tried. The babies are now in the box without the middle divider piece. Neither ended up having their babies in the breeder box.

"Great item!"

My husband got me a few guppies that apparently had been pregnant. I tested both my tank and box water to find a big difference in Ammonia levels. I took out the part that separates the parent from the babies. They are now all back together, living as peaceably as fish can. Good quality and easy to take apart. So overall, this is a functioning product with little issues. I really liked the fact I could add an airline for water flow.

"It is nice and clear."

The funnel tray is placed too high within the box. I don't see how they send used stuff out as new! The seller, Pawfly, was very nice about it. It would have been nice to have the suction cups. Still, everything else about the box is great! Suction cups do not hold the box up under its own weight. If you have a smaller tank, the Lee's may be the better choice.
