"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.

"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!

"The large is VERY SMALL."

It's plastic but I have used it for several months and it’s help up well. I took the out of the tank and put them in mugs but it was not practical. When I came across this one that showed the actual inner dimensions, I was impressed. As with many plastics, if it isn't thick enough, then it can break. I have two female Bettas and a Pleco in a filtered, heated 15-gallon tank. I do suggest leaving the lid above the waterline, however, as it has two holes. No trying to get mom back out while trying to keep babies in.

"It's nice an big."

It comes with 2 suction cups for when you want it to stay in place. Suction cups do not hold the box up under its own weight. Petzilla is larger in size which reduces crowding as the babies grow. I put three pregnant females in the box immediately. I am using several to sort through some fish I am breeding. Fits nicely in a size 10 gallon tank. The dividers only work with the fry drop in place.

"This product is great!"

He's happy just sitting on his plant blowing bubbles. We picked this up to use as a secondary QT box for our reef tank. So overall, this is a functioning product with little issues. I can home one day and one was dead and all torn up from the sides. If you have a smaller tank, the Lee's may be the better choice. I'm using it as a nursery for baby guppies. So it IS possible for very small fry to slip through the slits.

"Works as expected."

That way the water still flows nicely in where mom is. One of them does not because you're supposed to add some sort of water rain bar. I feel like this breeder box is sturdier than some others that I've used. I have found one very unique use for it though. I really liked the fact I could add an airline for water flow. I put the rainbar into it so now they can't escape. It comes with 2 suction cups for when you want it to stay in place.

"Priced right."

You have to be really careful with shrimp or they die. I took out the part that separates the parent from the babies. I have two female Bettas and a Pleco in a filtered, heated 15-gallon tank. I own 7 of these isolation, breeding tanks. This keeps her area better airated and actually helps flow the babies out. We did have some get stuck in the edge of the partition. As with many plastics, if it isn't thick enough, then it can break.

This works better at protecting babies from mom than the one room nets. Both are designed for free floating. She doesn't seem very stressed, honestly, and likes to nap in the V's. I had a 2 pregnant guppies and bought this for them. This product is good for the price. It's unsightly with big uneven seams and extra fabric. In the picture, the Petzilla Aquarium Fish Breeder box is on the right.

"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.

"Every thing else is good."

It's a decent size for an internal breeder box. I never knew how important this was until tank cleaning time! It's plastic but I have used it for several months and it’s help up well. 5 gallon, but he was struggling to swim. The little air tube connection on the side is a nice addition too. I rated this 4 because it works great for the babies to live in for a bit. I feel like this breeder box is sturdier than some others that I've used.
