"Hope this is helpful."

This product is excellent, works fabulously. I am using several to sort through some fish I am breeding. I also like to put in a bowl with acclimating. Perfect for holding my guppy babies. We have 12 babies swimming around in our tank at the moment. They are now all back together, living as peaceably as fish can. I feel like this breeder box is sturdier than some others that I've used.

Marina 10942 Final Thoughts

"Works like a charm."

We had 2 pregnant fish in seperate halves with them seperated. I have noticed that with all they pieces in that food does not exit the bottom half. I got the medium and it's mostly the width of a 10 gallon tank. The breeder box has a decent size for isolating fish or dwarf shrimp. I have both the small and larger version. I feel like this breeder box is sturdier than some others that I've used. I also like that it goes in to the tank and not a hang on the outside type.

"No, really, I'm kidding."

With the fry drop in you have plenty of room for temporarily keeping the females. With the pump it's completely circulated and levels are normal. This is the best floating breeder I have ever tried. Guppy fry didn't escape and they look happy. We had 2 pregnant fish in seperate halves with them seperated. Easily accommodates two Molly's, swords or platy fish. I ordered this and it came next day.

"Thank you so much!"

I really liked the fact I could add an airline for water flow. I feel like this breeder box is sturdier than some others that I've used. The funnel tray is placed too high within the box. It comes with 2 suction cups for when you want it to stay in place. I bought one to try it out, and it's been excellent. I don't see how they send used stuff out as new! I feel like this breeder box is sturdier than some others that I've used.

3. Fish Tank Aquarium Water Separation Frame Net Fry Hatchery Breeder White

Unknown First Impressions

"Very glad I bought it."

I tested both my tank and box water to find a big difference in Ammonia levels. We have 12 babies swimming around in our tank at the moment. Super strong suction cups- I have both the small and large. It's a decent size for an internal breeder box. Took me a little while to figure it out but it worked for me. Lets in just enough new water to keep it clean, but not too much to have a current. It works as it is designed to do and kept my fry safe.

"Great purchase!"

Tired of my guppies eating their fry and found this. Worked well, water and air flow is minimum due to slots being very thin. Definitely worth buying if you need to separate fish for any reason. She doesn't seem very stressed, honestly, and likes to nap in the V's. The dividers only work with the fry drop in place. It is large enough for fish bigger than guppies. The little air tube connection on the side is a nice addition too.

"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.

Hffheer Final Thoughts

"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.

"Imperfect design."

When I came across this one that showed the actual inner dimensions, I was impressed. Took me a little while to figure it out but it worked for me. Perfect for holding my guppy babies.

"I did read reviews first."

No trying to get mom back out while trying to keep babies in. I actually put it in my 10 gallon baby fry tank. I didn't have the space for an external one. This product is excellent, works fabulously. No more babies swimming back up the cracks and getten eaten by mom. I had a 2 pregnant guppies and bought this for them.

"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 will update after the babies are born but so far this is great. Definitely worth buying if you need to separate fish for any reason. I put three pregnant females in the box immediately.

"Would highly recommend."

I currently have about 30 or so new babies in it. Fits nicely in a size 10 gallon tank. My kids observe the fish and write notes about health and behavior. It works as it is designed to do and kept my fry safe. I have used other breeder boxes and like this one the best. The net is harder to see through but not for the casual observer. I left it out and the babies were sneaking out through that hole.

"Great product!"

This keeps her area better airated and actually helps flow the babies out. It's unsightly with big uneven seams and extra fabric. I use this all the time for fish or new plants. I also has a lid with snaps in place and has 2 slotted circles for dropping food in. 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. It would have been nice to have the suction cups.

"Priced right."

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. Suction cups do not hold the box up under its own weight. In the picture, the Petzilla Aquarium Fish Breeder box is on the right. With the fry drop in you have plenty of room for temporarily keeping the females. I got this so I can just put him in our 20-gallon hex with the angelfish.
