"Would buy again."

I also like to put in a bowl with acclimating. I got this so I can just put him in our 20-gallon hex with the angelfish. This product is good for the price. I've used several other floating breeders, and have always wished they were larger. So it IS possible for very small fry to slip through the slits. I didn't have the space for an external one. If that bottom piece fit better it would have been perfect.

"Imperfect design."

Less than 2 days and already received a replacement. I have two female Bettas and a Pleco in a filtered, heated 15-gallon tank. Not sure why some people are complaining the the separating tray floats. It's roomy and gives them space to move around. I feel like this breeder box is sturdier than some others that I've used. I feel like this breeder box is sturdier than some others that I've used. We had 2 pregnant fish in seperate halves with them seperated.

LJSLYJ First Impressions

"So this is what I did."

It comes with 2 removable dividers and a removable fry drop slotted piece. If you have a smaller tank, the Lee's may be the better choice. This product is excellent, works fabulously. Breeder nets are available in many sizes including larger than both boxes. I currently have about 30 or so new babies in it. The suction cups were adequate and held the breeder on to the glass fairly well. The funnel tray is placed too high within the box.

"Assembly was fine."

I'll put the bag from the pet shop in it and cut it open. We had 2 pregnant fish in seperate halves with them seperated. I gave 4 stars becauses the mesh gets algae ridden pretty easily and stained green. It is large enough for fish bigger than guppies. It's a decent size for an internal breeder box. I put the rainbar into it so now they can't escape. This keeps her area better airated and actually helps flow the babies out.

Petzilla PBI-1 Final Thoughts

"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.

"Great external refugium."

Super strong suction cups- I have both the small and large. We did have some get stuck in the edge of the partition. Good size and I like the separated chambers. With the fry drop in you have plenty of room for temporarily keeping the females. I had a 2 pregnant guppies and bought this for them. Still, everything else about the box is great! Guppy fry didn't escape and they look happy.

"This product is great."

Unlike the males, female Bettas should get along together. The funnel tray is placed too high within the box. I do suggest leaving the lid above the waterline, however, as it has two holes. Apparently my purple Betta, Dragonfruit, did not get the memo. I currently have about 30 or so new babies in it. I own 7 of these isolation, breeding tanks. Two days later and we have about 20 babies swimming in the bottom part of the box.

"Works good."

The baby fish were able to swim from the bottom back to the time in the corners. Guppy fry didn't escape and they look happy. First one arrived used with gravel and a hole in it. He's happy just sitting on his plant blowing bubbles. I really like that it has suction cups, and is very sturdy on the glass. He's happy just sitting on his plant blowing bubbles.

"It is nice and clear."

Perfect for holding my guppy babies. I ordered this product for my Balloon mollie babies. Neither ended up having their babies in the breeder box. It is large enough for fish bigger than guppies. I have noticed that with all they pieces in that food does not exit the bottom half. If that bottom piece fit better it would have been perfect. It's unsightly with big uneven seams and extra fabric.

"I really like it."

That way the water still flows nicely in where mom is. So far, those have both held up, so the non-locking lid has not been an issue. Kind of a pain to remove the lid and feed the fry. Undeniably the best seller I've encountered. I highly recommend this product, simple and easy to use! I currently have about 30 or so new babies in it. I ordered this and it came next day.

"It's nice an big."

There are slats in the bottom for the babies to escape to, to keep from being eaten. I didn't have the space for an external one. The baby fish were able to swim from the bottom back to the time in the corners. He had room to still swim around and I didn't feel too guilty. With the fry drop in you have plenty of room for temporarily keeping the females. Hope you found this review helpful! So overall, this is a functioning product with little issues.

"Would highly recommend."

It's a decent size for an internal breeder box. Mine's been doing fine and very useful. No more babies swimming back up the cracks and getten eaten by mom. That's why I took time to come back. I own 7 of these isolation, breeding tanks. It's roomy and gives them space to move around. So it IS possible for very small fry to slip through the slits.

"A good purchase for."

I'm using it as a nursery for baby guppies. Definitely worth buying if you need to separate fish for any reason. If that bottom piece fit better it would have been perfect. I do suggest leaving the lid above the waterline, however, as it has two holes. Petzilla is larger in size which reduces crowding as the babies grow. The dimensions for the large size are approximately 8. This product is good for the price.

"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 is it."

It comes with 2 removable dividers and a removable fry drop slotted piece. The Petzilla and Lee's make observations easier. Each of the four corners I thought had a cap. Both are designed for free floating. I highly recommend this product, simple and easy to use! For me, the geatest feature is that it floats and floats evenly. The little air tube connection on the side is a nice addition too.
