Finnex HB-211 First Impressions

"It did the trick!"

He had room to still swim around and I didn't feel too guilty. The babies are now in the box without the middle divider piece. With the pump it's completely circulated and levels are normal. The dimensions for the large size are approximately 8. Both are designed for free floating. I will definitely buy these kind of breeder again. The tube for the bubbler is a nice touch.

Finnex HB-211 Final Thoughts

"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.

2. Live Betta Halfmoon Plakat Fish

Generic First Impressions

"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.

Generic Final Thoughts

"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.

Penn-Plax AN2 First Impressions

"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.

"I recommend this box."

With everything out the tank seems to stay really clean. Took me a little while to figure it out but it worked for me. One of them does not because you're supposed to add some sort of water rain bar. They are impossible to reach once it it attached. Not as sturdy as I thought but perfect for what I wanted. With everything out the tank seems to stay really clean. I also like that it goes in to the tank and not a hang on the outside type.

Superfish 545010 Final Thoughts

"It is perfect!"

My other one was fine but I brought her out so she wouldn't get hurt. This keeps her area better airated and actually helps flow the babies out. I have noticed that with all they pieces in that food does not exit the bottom half. Hope you found this review helpful! I usually wait to write reviews but I am already impressed with this breeding box. It's unsightly with big uneven seams and extra fabric. Took me a little while to figure it out but it worked for me.

Forgun First Impressions

"Priced right."

She doesn't seem very stressed, honestly, and likes to nap in the V's. They seemed scared at first but calmed down after about 30 minutes. Lets in just enough new water to keep it clean, but not too much to have a current. I will update after the babies are born but so far this is great. It is large enough for fish bigger than guppies. They are impossible to reach once it it attached. This product is excellent, works fabulously.

"Good plastic box."

Neither ended up having their babies in the breeder box. Instead of catching babies, I simply leave the mom in the top piece. I tested both my tank and box water to find a big difference in Ammonia levels. It works as it is designed to do and kept my fry safe. Undeniably the best seller I've encountered. The Petzilla and Lee's make observations easier. I'm using it as a nursery for baby guppies.

Cobalt Aquatics 45122 First Impressions

"It's all very exciting."

Hope you found this review helpful! We need to do mare to make sure bettas are treated better in pet stores, though. This works better at protecting babies from mom than the one room nets. The suction cups hold well, and it has floating handle chambers as a backup. Lets in just enough new water to keep it clean, but not too much to have a current. He had room to still swim around and I didn't feel too guilty. I have two female Bettas and a Pleco in a filtered, heated 15-gallon tank.

Cobalt Aquatics 45122 Final Thoughts

"Easy to install."

The lid doesn't lock in place too snugly which make it easy to open. With everything out the tank seems to stay really clean. I also like to put in a bowl with acclimating. It is large enough for fish bigger than guppies. That way the water still flows nicely in where mom is. I had a 2 pregnant guppies and bought this for them. I left it out and the babies were sneaking out through that hole.

"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.

"He's about 3."

Unlike the males, female Bettas should get along together. The baby fish were able to swim from the bottom back to the time in the corners. Perfect for holding my guppy babies. It's unsightly with big uneven seams and extra fabric. I've used several other floating breeders, and have always wished they were larger. I have both the small and larger version. If you have a smaller tank, the Lee's may be the better choice.

I bought one to try it out, and it's been excellent. Less than 2 days and already received a replacement. Instead of catching babies, I simply leave the mom in the top piece.

Easily accommodates two Molly's, swords or platy fish. My husband got me a few guppies that apparently had been pregnant. Neither ended up having their babies in the breeder box. I'll put the bag from the pet shop in it and cut it open. I'll put the bag from the pet shop in it and cut it open. Not sure why some people are complaining the the separating tray floats.
