"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.

"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.

"Works like a charm."

The tube for the bubbler is a nice touch. It would have been nice to have the suction cups. Tired of my guppies eating their fry and found this. Instead of catching babies, I simply leave the mom in the top piece. I have found one very unique use for it though. I personally use these to introduce smaller fish into my community tanks. There is a grate that sits about an inch above the bottom of the box.

I gave 4 stars becauses the mesh gets algae ridden pretty easily and stained green. It comes with 2 removable dividers and a removable fry drop slotted piece. Both are designed for free floating.

"Mines in the mail ."

I have found one very unique use for it though. There is a grate that sits about an inch above the bottom of the box. As with many plastics, if it isn't thick enough, then it can break. I put three pregnant females in the box immediately. 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. I personally use these to introduce smaller fish into my community tanks.

"Good plastic box."

It works as it is designed to do and kept my fry safe. I have two female Bettas and a Pleco in a filtered, heated 15-gallon tank. If that bottom piece fit better it would have been perfect. With the fry drop in you have plenty of room for temporarily keeping the females. Lets in just enough new water to keep it clean, but not too much to have a current. They seemed scared at first but calmed down after about 30 minutes. This product is good for the price.

"Assembly was fine."

With the fry drop removed you get a really nice size little tank. So far, those have both held up, so the non-locking lid has not been an issue. I also like to put in a bowl with acclimating.

We caught momma the day before she had them and removed her after.

"Definitely recommend."

Less than 2 days and already received a replacement. Guppy fry didn't escape and they look happy. First one arrived used with gravel and a hole in it. Definitely worth buying if you need to separate fish for any reason. I had a 2 pregnant guppies and bought this for them. I got the medium and it's mostly the width of a 10 gallon tank. As with many plastics, if it isn't thick enough, then it can break.

"So it's a good size."

I really liked the fact I could add an airline for water flow. The lid doesn't lock in place too snugly which make it easy to open. If that bottom piece fit better it would have been perfect. I don't see how they send used stuff out as new! For me, the geatest feature is that it floats and floats evenly. So it IS possible for very small fry to slip through the slits. Future design improvement- less room for fry, more room for moms.

"Great item!"

I also like that it goes in to the tank and not a hang on the outside type. If that bottom piece fit better it would have been perfect. They are now all back together, living as peaceably as fish can. I took out the part that separates the parent from the babies. It is large enough for fish bigger than guppies. It would have been nice to have the suction cups. I didn't have the space for an external one.

I took the out of the tank and put them in mugs but it was not practical. Neither ended up having their babies in the breeder box. I actually put it in my 10 gallon baby fry tank. We did have some get stuck in the edge of the partition. So it IS possible for very small fry to slip through the slits. The funnel tray is placed too high within the box.
