Penn-Plax AN2 First Impressions

"The thing is awesome!"

So it IS possible for very small fry to slip through the slits. Instead of catching babies, I simply leave the mom in the top piece. I have used other breeder boxes and like this one the best. Not as sturdy as I thought but perfect for what I wanted. With the fry drop removed you get a really nice size little tank. Worked great for me and my need to separate babies from the rest of the tank. Tired of my guppies eating their fry and found this.

Penn-Plax AN2 Final Thoughts

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

Unlike the males, female Bettas should get along together. Easily accommodates two Molly's, swords or platy fish. They seemed scared at first but calmed down after about 30 minutes. Especially if you plan to hold the babies there for a while. Kind of a pain to remove the lid and feed the fry. I put three pregnant females in the box immediately. Suction cups do not hold the box up under its own weight.

Penn-Plax NB1 First Impressions

"Great purchase!"

My husband got me a few guppies that apparently had been pregnant. This is my first breeder box so I cant really compare with other brands. I ordered this and it came next day. Tired of my guppies eating their fry and found this. I put the rainbar into it so now they can't escape. Instead of catching babies, I simply leave the mom in the top piece. I really liked the fact I could add an airline for water flow.

Penn-Plax NB1 Final Thoughts

"I really like it."

It is large enough for fish bigger than guppies. The lid doesn't lock in place too snugly which make it easy to open. So it IS possible for very small fry to slip through the slits. This product is excellent, works fabulously. I bought one to try it out, and it's been excellent. I will definitely buy these kind of breeder again. I will update after the babies are born but so far this is great.

WEAVERBIRD First Impressions

"It's sturdy so far."

Unlike the males, female Bettas should get along together. I got the medium and it's mostly the width of a 10 gallon tank. It's roomy and gives them space to move around. She doesn't seem very stressed, honestly, and likes to nap in the V's. No trying to get mom back out while trying to keep babies in. For me, the geatest feature is that it floats and floats evenly. Tired of my guppies eating their fry and found this.

WEAVERBIRD Final Thoughts

"Every thing else is good."

I put the rainbar into it so now they can't escape. He had room to still swim around and I didn't feel too guilty. Each of the four corners I thought had a cap. Perfect for holding my guppy babies. Both are designed for free floating. I gave 4 stars becauses the mesh gets algae ridden pretty easily and stained green. I really like that it has suction cups, and is very sturdy on the glass.

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.

PUPUZAO Final Thoughts

"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.

"Imperfect design."

I use this all the time for fish or new plants. I've used several other floating breeders, and have always wished they were larger. I feel like this breeder box is sturdier than some others that I've used. It comes with 2 removable dividers and a removable fry drop slotted piece. I am using several to sort through some fish I am breeding. Mine's been doing fine and very useful. I really liked the fact I could add an airline for water flow.

"Very useful."

We had 2 pregnant fish in seperate halves with them seperated. The breeder box has a decent size for isolating fish or dwarf shrimp. With the fry drop removed you get a really nice size little tank. No more babies swimming back up the cracks and getten eaten by mom. So overall, this is a functioning product with little issues. I left it out and the babies were sneaking out through that hole. I do suggest leaving the lid above the waterline, however, as it has two holes.

Cobalt Aquatics 45122 First Impressions

"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. He had room to still swim around and I didn't feel too guilty. I have two female Bettas and a Pleco in a filtered, heated 15-gallon tank.

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.

Galapara First Impressions

"Every thing else is good."

Undeniably the best seller I've encountered. The plastic is much thicker than the last box I bought for the same price. I'll put the bag from the pet shop in it and cut it open. The babies are now in the box without the middle divider piece. I don't see how they send used stuff out as new! 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.

"Flow is just a trickle."

The babies are now in the box without the middle divider piece. Petzilla is larger in size which reduces crowding as the babies grow. I do suggest leaving the lid above the waterline, however, as it has two holes. Mine's been doing fine and very useful. First one arrived used with gravel and a hole in it. The plastic is much thicker than the last box I bought for the same price. The little air tube connection on the side is a nice addition too.

I highly recommend this product, simple and easy to use! I took out the part that separates the parent from the babies. This is the best floating breeder I have ever tried.

"I would buy again!"

The tube for the bubbler is a nice touch. Undeniably the best seller I've encountered. Guppy fry didn't escape and they look happy. It's unsightly with big uneven seams and extra fabric. Definitely worth buying if you need to separate fish for any reason. When I came across this one that showed the actual inner dimensions, I was impressed. I gave 4 stars becauses the mesh gets algae ridden pretty easily and stained green.

"It is nice and clear."

I also has a lid with snaps in place and has 2 slotted circles for dropping food in. This is the best floating breeder I have ever tried. I do suggest leaving the lid above the waterline, however, as it has two holes. It's plastic but I have used it for several months and it’s help up well. I have noticed that with all they pieces in that food does not exit the bottom half. This product is excellent, works fabulously.

"Wash before use."

The breeder box has a decent size for isolating fish or dwarf shrimp. I own 7 of these isolation, breeding tanks. Neither ended up having their babies in the breeder box. I bought one to try it out, and it's been excellent. Less than 2 days and already received a replacement. Instead of catching babies, I simply leave the mom in the top piece. The baby fish were able to swim from the bottom back to the time in the corners.
