"It's nice an big."

With the pump it's completely circulated and levels are normal. Lets in just enough new water to keep it clean, but not too much to have a current. It's plastic but I have used it for several months and it’s help up well. The breeder box has a decent size for isolating fish or dwarf shrimp. I don't see how they send used stuff out as new! I really liked the fact I could add an airline for water flow. Fits nicely in a size 10 gallon tank.

capetsma Final Thoughts

"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.

"It actually works!"

I highly recommend this product, simple and easy to use! I took out the part that separates the parent from the babies. This is the best floating breeder I have ever tried. She doesn't seem very stressed, honestly, and likes to nap in the V's. Now he's chilling in quarantine until he heals. First one arrived used with gravel and a hole in it. The suction cups hold well, and it has floating handle chambers as a backup.

"Thank you so much!"

This works better at protecting babies from mom than the one room nets. Each of the four corners I thought had a cap. I bought one to try it out, and it's been excellent. The tube for the bubbler is a nice touch. I feel like this breeder box is sturdier than some others that I've used. The tube for the bubbler is a nice touch. This product is good for the price.

"Works like a charm."

We had 2 pregnant fish in seperate halves with them seperated. I have noticed that with all they pieces in that food does not exit the bottom half. I got the medium and it's mostly the width of a 10 gallon tank. The breeder box has a decent size for isolating fish or dwarf shrimp. I have both the small and larger version. I feel like this breeder box is sturdier than some others that I've used. I also like that it goes in to the tank and not a hang on the outside type.

"Great purchase!"

Tired of my guppies eating their fry and found this. Worked well, water and air flow is minimum due to slots being very thin. Definitely worth buying if you need to separate fish for any reason. She doesn't seem very stressed, honestly, and likes to nap in the V's. The dividers only work with the fry drop in place. It is large enough for fish bigger than guppies. The little air tube connection on the side is a nice addition too.

Bashsea First Impressions

"Works like a charm."

It's unsightly with big uneven seams and extra fabric. There's only one issue with this unit. The lid doesn't lock in place too snugly which make it easy to open. Neither ended up having their babies in the breeder box. As with many plastics, if it isn't thick enough, then it can break. As with many plastics, if it isn't thick enough, then it can break.

"The large is VERY SMALL."

Good size and I like the separated chambers. No more babies swimming back up the cracks and getten eaten by mom. She doesn't seem very stressed, honestly, and likes to nap in the V's. Neither ended up having their babies in the breeder box. I feel like this breeder box is sturdier than some others that I've used. Worked great for me and my need to separate babies from the rest of the tank. I'm using it as a nursery for baby guppies.

I got this so I can just put him in our 20-gallon hex with the angelfish. I currently have about 30 or so new babies in it. It would have been nice to have the suction cups. I currently have about 30 or so new babies in it. I can home one day and one was dead and all torn up from the sides. The breeder box has a decent size for isolating fish or dwarf shrimp. That way the water still flows nicely in where mom is.

"Awesome product."

I also has a lid with snaps in place and has 2 slotted circles for dropping food in. The funnel tray is placed too high within the box. I usually wait to write reviews but I am already impressed with this breeding box. Worked well, water and air flow is minimum due to slots being very thin.

"Great design."

I really like that it has suction cups, and is very sturdy on the glass. Two days later and we have about 20 babies swimming in the bottom part of the box. I will definitely buy these kind of breeder again. No trying to get mom back out while trying to keep babies in. We picked this up to use as a secondary QT box for our reef tank. Apparently my purple Betta, Dragonfruit, did not get the memo. With the fry drop removed you get a really nice size little tank.

"I did read reviews first."

That way the water still flows nicely in where mom is. With the fry drop removed you get a really nice size little tank. The dimensions for the large size are approximately 8. I bought one to try it out, and it's been excellent. I gave 4 stars becauses the mesh gets algae ridden pretty easily and stained green. We did have some get stuck in the edge of the partition. One of them does not because you're supposed to add some sort of water rain bar.

This is my first breeder box so I cant really compare with other brands. Super strong suction cups- I have both the small and large. It works as it is designed to do and kept my fry safe. Both are designed for free floating. The dimensions for the large size are approximately 8. Unlike the males, female Bettas should get along together.

Suction cups do not hold the box up under its own weight. This product is excellent, works fabulously. Kind of a pain to remove the lid and feed the fry.
