"Clear plastic EZ to use."

Future design improvement- less room for fry, more room for moms. I put three pregnant females in the box immediately. Not sure why some people are complaining the the separating tray floats. I popped this together in a minute and it was in the tank in another minute. We picked this up to use as a secondary QT box for our reef tank. I got the medium and it's mostly the width of a 10 gallon tank. I feel like this breeder box is sturdier than some others that I've used.

"Great design."

Unlike the males, female Bettas should get along together. Neither ended up having their babies in the breeder box. Unlike the males, female Bettas should get along together. This product is good for the price. This keeps her area better airated and actually helps flow the babies out. I am using several to sort through some fish I am breeding. It would have been nice to have the suction cups.

"Just Kidding!"

With everything out the tank seems to stay really clean. I highly recommend this product, simple and easy to use! The tube for the bubbler is a nice touch. I never knew how important this was until tank cleaning time! Not as sturdy as I thought but perfect for what I wanted. It's a decent size for an internal breeder box. Fits nicely in a size 10 gallon tank.

"Over all pretty good."

As with many plastics, if it isn't thick enough, then it can break. Guppy fry didn't escape and they look happy. Definitely worth buying if you need to separate fish for any reason. There is a grate that sits about an inch above the bottom of the box. My husband got me a few guppies that apparently had been pregnant. Instead of catching babies, I simply leave the mom in the top piece. The plastic is much thicker than the last box I bought for the same price.

"Great product!"

I do suggest leaving the lid above the waterline, however, as it has two holes. I tested both my tank and box water to find a big difference in Ammonia levels. He had room to still swim around and I didn't feel too guilty. He's happy just sitting on his plant blowing bubbles. The babies are now in the box without the middle divider piece. With everything out the tank seems to stay really clean. It's unsightly with big uneven seams and extra fabric.

"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.

"It is nice and clear."

The Petzilla and Lee's make observations easier. I gave 4 stars becauses the mesh gets algae ridden pretty easily and stained green. I don't see how they send used stuff out as new! The baby fish were able to swim from the bottom back to the time in the corners. We did have some get stuck in the edge of the partition. It would have been nice to have the suction cups. Good size and I like the separated chambers.

"This was a good buy."

No trying to get mom back out while trying to keep babies in. I ordered this product for my Balloon mollie babies. Kind of a pain to remove the lid and feed the fry. I also like that it goes in to the tank and not a hang on the outside type. The plastic is much thicker than the last box I bought for the same price. I put the rainbar into it so now they can't escape. It works as it is designed to do and kept my fry safe.

"Very easy to assemble."

It's roomy and gives them space to move around. I had a 2 pregnant guppies and bought this for them. If that bottom piece fit better it would have been perfect. I really liked the fact I could add an airline for water flow. It is large enough for fish bigger than guppies. I tested both my tank and box water to find a big difference in Ammonia levels. I bought one to try it out, and it's been excellent.

"Priced right."

So overall, this is a functioning product with little issues. I own 7 of these isolation, breeding tanks. For me, the geatest feature is that it floats and floats evenly. Suction cups do not hold the box up under its own weight. In the picture, the Petzilla Aquarium Fish Breeder box is on the right. With the fry drop in you have plenty of room for temporarily keeping the females. I got this so I can just put him in our 20-gallon hex with the angelfish.

"Keeps fish contained."

This works better at protecting babies from mom than the one room nets. This product is good for the price. I tested both my tank and box water to find a big difference in Ammonia levels. Not as sturdy as I thought but perfect for what I wanted. We caught momma the day before she had them and removed her after. Worked well, water and air flow is minimum due to slots being very thin. That's why I took time to come back.

Super strong suction cups- I have both the small and large. Future design improvement- less room for fry, more room for moms. I really like that it has suction cups, and is very sturdy on the glass. Apparently my purple Betta, Dragonfruit, did not get the memo. It is large enough for fish bigger than guppies. The dividers only work with the fry drop in place. This product is excellent, works fabulously.

"He's happy, so I'm happy."

So far, those have both held up, so the non-locking lid has not been an issue. I really like the design of this breeder box. We had 2 pregnant fish in seperate halves with them seperated. The tube for the bubbler is a nice touch. I personally use these to introduce smaller fish into my community tanks. I actually put it in my 10 gallon baby fry tank. We did have some get stuck in the edge of the partition.
