"I'm very pleased with it."

They seemed scared at first but calmed down after about 30 minutes. This product is excellent, works fabulously. We have 12 babies swimming around in our tank at the moment. Super strong suction cups- I have both the small and large. He's happy just sitting on his plant blowing bubbles. Each of the four corners I thought had a cap. The Petzilla and Lee's make observations easier.

Lee's 10255 Final Thoughts

"The thing is awesome!"

I use this all the time for fish or new plants. No more babies swimming back up the cracks and getten eaten by mom. It works as it is designed to do and kept my fry safe. He had room to still swim around and I didn't feel too guilty. I bought one to try it out, and it's been excellent. Lets in just enough new water to keep it clean, but not too much to have a current. That way the water still flows nicely in where mom is.

"This product is great."

Super strong suction cups- I have both the small and large. The breeder box has a decent size for isolating fish or dwarf shrimp. I gave 4 stars becauses the mesh gets algae ridden pretty easily and stained green. She doesn't seem very stressed, honestly, and likes to nap in the V's. Super strong suction cups- I have both the small and large. For me, the geatest feature is that it floats and floats evenly. The lid doesn't lock in place too snugly which make it easy to open.

"Works like a charm."

I usually wait to write reviews but I am already impressed with this breeding box. He's happy just sitting on his plant blowing bubbles. So overall, this is a functioning product with little issues. The little air tube connection on the side is a nice addition too. I have two female Bettas and a Pleco in a filtered, heated 15-gallon tank. With the fry drop in you have plenty of room for temporarily keeping the females. We caught momma the day before she had them and removed her after.

"It's all very exciting."

Hope you found this review helpful! We need to do mare to make sure bettas are treated better in pet stores, though. This works better at protecting babies from mom than the one room nets. The suction cups hold well, and it has floating handle chambers as a backup. Lets in just enough new water to keep it clean, but not too much to have a current.

Cobalt Aquatics 45122 Final Thoughts

"Easy to install."

The lid doesn't lock in place too snugly which make it easy to open. With everything out the tank seems to stay really clean. I also like to put in a bowl with acclimating. It is large enough for fish bigger than guppies. That way the water still flows nicely in where mom is. I had a 2 pregnant guppies and bought this for them. I left it out and the babies were sneaking out through that hole.

"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.

"It did the trick!"

The lid doesn't lock in place too snugly which make it easy to open. There are slats in the bottom for the babies to escape to, to keep from being eaten. Instead of catching babies, I simply leave the mom in the top piece. 5 gallon, but he was struggling to swim. I really like the design of this breeder box. I can home one day and one was dead and all torn up from the sides. I ordered this product for my Balloon mollie babies.

"Works good."

If you have a smaller tank, the Lee's may be the better choice. Apparently my purple Betta, Dragonfruit, did not get the memo. It's plastic but I have used it for several months and it’s help up well. We have 12 babies swimming around in our tank at the moment. Tired of my guppies eating their fry and found this. The dividers only work with the fry drop in place. Petzilla is larger in size which reduces crowding as the babies grow.

"It is extremely small."

The suction cups hold well, and it has floating handle chambers as a backup. I gave 4 stars becauses the mesh gets algae ridden pretty easily and stained green. We have 12 babies swimming around in our tank at the moment. The plastic is much thicker than the last box I bought for the same price. I rated this 4 because it works great for the babies to live in for a bit. 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.

WEAVERBIRD Final Thoughts

"Arrived on time."

Easily accommodates two Molly's, swords or platy fish. I put three pregnant females in the box immediately. The dividers only work with the fry drop in place. I personally use these to introduce smaller fish into my community tanks. With the fry drop in you have plenty of room for temporarily keeping the females. I highly recommend this product, simple and easy to use! When I came across this one that showed the actual inner dimensions, I was impressed.

"Arrived on time."

This works better at protecting babies from mom than the one room nets. It's roomy and gives them space to move around. Each of the four corners I thought had a cap. I feel like this breeder box is sturdier than some others that I've used. He's happy just sitting on his plant blowing bubbles. 5 gallon, but he was struggling to swim. I really like the design of this breeder box.

"I liked this breeder box."

Not sure why some people are complaining the the separating tray floats. I've used several other floating breeders, and have always wished they were larger. With the fry drop in you have plenty of room for temporarily keeping the females. I'll put the bag from the pet shop in it and cut it open. The funnel tray is placed too high within the box. It works as it is designed to do and kept my fry safe. This product is excellent, works fabulously.

"Flow is just a trickle."

It is large enough for fish bigger than guppies. I usually wait to write reviews but I am already impressed with this breeding box. It comes with 2 suction cups for when you want it to stay in place. The babies are now in the box without the middle divider piece. We did have some get stuck in the edge of the partition. If you have a smaller tank, the Lee's may be the better choice. There's only one issue with this unit.

"Will return."

Worked great for me and my need to separate babies from the rest of the tank. If that bottom piece fit better it would have been perfect. It is large enough for fish bigger than guppies. Unlike the males, female Bettas should get along together. The Petzilla and Lee's make observations easier. The dividers only work with the fry drop in place. I have found one very unique use for it though.

"Suction cups are good."

The tube for the bubbler is a nice touch. It's unsightly with big uneven seams and extra fabric. The net is harder to see through but not for the casual observer. With the fry drop removed you get a really nice size little tank. I bought one to try it out, and it's been excellent. That's why I took time to come back.

"Priced right."

Suction cups do not hold the box up under its own weight. This is my first breeder box so I cant really compare with other brands. I usually wait to write reviews but I am already impressed with this breeding box. I personally use these to introduce smaller fish into my community tanks. I have both the small and larger version. The little air tube connection on the side is a nice addition too. I got this so I can just put him in our 20-gallon hex with the angelfish.

"Every thing else is good."

I own 7 of these isolation, breeding tanks. The lid doesn't lock in place too snugly which make it easy to open. 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. As with many plastics, if it isn't thick enough, then it can break. The plastic is much thicker than the last box I bought for the same price. Two days later and we have about 20 babies swimming in the bottom part of the box.
