"Tried him in a 3."

So overall, this is a functioning product with little issues. It comes with 2 suction cups for when you want it to stay in place. It comes with 2 suction cups for when you want it to stay in place. Perfect for holding my guppy babies. It works as it is designed to do and kept my fry safe. That way the water still flows nicely in where mom is. I have both the small and larger version.

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.

"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.

Petzilla PBI-2 Final Thoughts

"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.

"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.

Petzilla PBI-3 Final Thoughts

"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 didn't have the space for an external one. I bought one to try it out, and it's been excellent. There is a grate that sits about an inch above the bottom of the box.

"So the netting like."

I will definitely buy these kind of breeder again. With the fry drop in you have plenty of room for temporarily keeping the females. It's a decent size for an internal breeder box. Hope you found this review helpful! I put the rainbar into it so now they can't escape. Mine's been doing fine and very useful. They are impossible to reach once it it attached.

Guppy fry didn't escape and they look happy. I really like the design of this breeder box. I tested both my tank and box water to find a big difference in Ammonia levels. I tested both my tank and box water to find a big difference in Ammonia levels. The funnel tray is placed too high within the box.

The Petzilla and Lee's make observations easier. I own 7 of these isolation, breeding tanks. Worked well, water and air flow is minimum due to slots being very thin. Undeniably the best seller I've encountered. I highly recommend this product, simple and easy to use! It would have been nice to have the suction cups. My kids observe the fish and write notes about health and behavior.

It's roomy and gives them space to move around. It comes with 2 removable dividers and a removable fry drop slotted piece. It's a decent size for an internal breeder box. I feel like this breeder box is sturdier than some others that I've used. Guppy fry didn't escape and they look happy. I bought one to try it out, and it's been excellent. 5 gallon, but he was struggling to swim.

"Thank you so much!"

It's a decent size for an internal breeder box. I ordered this and it came next day. This keeps her area better airated and actually helps flow the babies out. With the pump it's completely circulated and levels are normal. No more babies swimming back up the cracks and getten eaten by mom. With everything out the tank seems to stay really clean. The suction cups were adequate and held the breeder on to the glass fairly well.

"I did read reviews first."

I own 7 of these isolation, breeding tanks. You have to be really careful with shrimp or they die. I tested both my tank and box water to find a big difference in Ammonia levels. I took the out of the tank and put them in mugs but it was not practical. I'm using it as a nursery for baby guppies. Apparently my purple Betta, Dragonfruit, did not get the memo. With everything out the tank seems to stay really clean.

"They held water well."

He's happy just sitting on his plant blowing bubbles. When I came across this one that showed the actual inner dimensions, I was impressed. My husband got me a few guppies that apparently had been pregnant. We have 12 babies swimming around in our tank at the moment. In the picture, the Petzilla Aquarium Fish Breeder box is on the right. Each of the four corners I thought had a cap. With the fry drop in you have plenty of room for temporarily keeping the females.

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.

"Works as expected."

I do suggest leaving the lid above the waterline, however, as it has two holes. Not sure why some people are complaining the the separating tray floats. I never knew how important this was until tank cleaning time! I will update after the babies are born but so far this is great. I'll put the bag from the pet shop in it and cut it open. First one arrived used with gravel and a hole in it. That's why I took time to come back.
