"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. I also like to put in a bowl with acclimating. Good quality and easy to take apart. I've used several other floating breeders, and have always wished they were larger. We caught momma the day before she had them and removed her after.

"Definitely recommend."

I popped this together in a minute and it was in the tank in another minute. I took the out of the tank and put them in mugs but it was not practical. I tested both my tank and box water to find a big difference in Ammonia levels. I use this all the time for fish or new plants. You have to be really careful with shrimp or they die. Worked great for me and my need to separate babies from the rest of the tank. I also has a lid with snaps in place and has 2 slotted circles for dropping food in.

Chnee Final Thoughts

"This is not a small box."

If you have a smaller tank, the Lee's may be the better choice. I took out the part that separates the parent from the babies. As with many plastics, if it isn't thick enough, then it can break. For me, the geatest feature is that it floats and floats evenly. For me, the geatest feature is that it floats and floats evenly. Future design improvement- less room for fry, more room for moms. Super strong suction cups- I have both the small and large.

Petzilla PBI-3 First Impressions

"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.

  • in-Tank Aquarium Breeder Box for Fish Tank, Breeding Incubator for Small Fish Hatchery, Acrylic Divider for Shrimp Clownfish Aggressive Fish Injured Fish, 8.1 x 3.5 x 4.1 Inch
  • This breeder box can prevent the baby fish from the adult fish's attack and improve the survival rate of the baby fish.
  • Multi-room Designed Divider - Space can be divided into as much as 3 small “rooms” as needed. Remove all the partitions to work as a large hatchery box.
  • 0.5mm Super-slim Isolation Gap - Thinner than the gap of the fish eggs plate, effectively protect the baby fish from the invasion of the adult fish.
  • Original Design of 4 stands to Make It Steady - The W funnel won't be floating because of the water pressure when it's not placed upright.
  • No need to open the cover when feeding because of the upgraded design with a feeding hole on the top. New suctions made with Environment-friendly materials, better adsorption.

"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.

PUPUZAO First Impressions

"Clear plastic EZ to use."

I use this all the time for fish or new plants. I bought one to try it out, and it's been excellent. I personally use these to introduce smaller fish into my community tanks. This keeps her area better airated and actually helps flow the babies out. I got this so I can just put him in our 20-gallon hex with the angelfish. The Petzilla and Lee's make observations easier. The plastic is much thicker than the last box I bought for the same price.

"Second was fine."

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. I had a 2 pregnant guppies and bought this for them. I've used several other floating breeders, and have always wished they were larger. I do suggest leaving the lid above the waterline, however, as it has two holes. It would have been nice to have the suction cups. I got this so I can just put him in our 20-gallon hex with the angelfish.

"This product is great!"

I have two female Bettas and a Pleco in a filtered, heated 15-gallon tank. That's why I took time to come back. The seller, Pawfly, was very nice about it. 5 gallon, but he was struggling to swim. It's unsightly with big uneven seams and extra fabric. I usually wait to write reviews but I am already impressed with this breeding box. Good quality and easy to take apart.

Senzeal SZLUS-0566 Final Thoughts

"Every thing else is good."

5 gallon, but he was struggling to swim. I gave 4 stars becauses the mesh gets algae ridden pretty easily and stained green. The seller, Pawfly, was very nice about it. I highly recommend this product, simple and easy to use! Unlike the males, female Bettas should get along together. I have noticed that with all they pieces in that food does not exit the bottom half. I have safe little fry and more to come!

"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.

"I love this little box."

Hope you found this review helpful! My kids observe the fish and write notes about health and behavior. This product is good for the price. Suction cups do not hold the box up under its own weight. I am using several to sort through some fish I am breeding. This is the best floating breeder I have ever tried. No trying to get mom back out while trying to keep babies in.

"Assembly was fine."

I ordered this product for my Balloon mollie babies. I really liked the fact I could add an airline for water flow. The dividers only work with the fry drop in place. Not as sturdy as I thought but perfect for what I wanted. Not sure why some people are complaining the the separating tray floats. He's happy just sitting on his plant blowing bubbles. The baby fish were able to swim from the bottom back to the time in the corners.

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.

"A good purchase for."

We did have some get stuck in the edge of the partition. They are now all back together, living as peaceably as fish can. You have to be really careful with shrimp or they die. Future design improvement- less room for fry, more room for moms. The dimensions for the large size are approximately 8. Still, everything else about the box is great! Guppy fry didn't escape and they look happy.

"Very light!"

The seller, Pawfly, was very nice about it. There is a grate that sits about an inch above the bottom of the box. I own 7 of these isolation, breeding tanks. This product is excellent, works fabulously. Now he's chilling in quarantine until he heals. I bought one to try it out, and it's been excellent. Neither ended up having their babies in the breeder box.

I am using several to sort through some fish I am breeding. My husband got me a few guppies that apparently had been pregnant. It's roomy and gives them space to move around.
