"I'm happy with this."

Much easier to use and install than those tank partitions. I have both the small and larger version. I will update after the babies are born but so far this is great. There's only one issue with this unit. We have 12 babies swimming around in our tank at the moment. We picked this up to use as a secondary QT box for our reef tank. Took me a little while to figure it out but it worked for me.

"So this is what I did."

If you have a smaller tank, the Lee's may be the better choice. Now he's chilling in quarantine until he heals. I also like that it goes in to the tank and not a hang on the outside type. There's only one issue with this unit. It is large enough for fish bigger than guppies. With the fry drop removed you get a really nice size little tank. I put three pregnant females in the box immediately.

"This product is great."

When I came across this one that showed the actual inner dimensions, I was impressed. This works better at protecting babies from mom than the one room nets. We need to do mare to make sure bettas are treated better in pet stores, though. It's unsightly with big uneven seams and extra fabric. He had room to still swim around and I didn't feel too guilty. Undeniably the best seller I've encountered. This product is good for the price.

"Mines in the mail ."

Perfect for holding my guppy babies. This is the best floating breeder I have ever tried. I didn't have the space for an external one. The dimensions for the large size are approximately 8. 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. I have safe little fry and more to come!

You have to be really careful with shrimp or they die. He had room to still swim around and I didn't feel too guilty. I currently have about 30 or so new babies in it.

"Great purchase!"

Worked well, water and air flow is minimum due to slots being very thin. I feel like this breeder box is sturdier than some others that I've used. I really like the design of this breeder box. I personally use these to introduce smaller fish into my community tanks. They seemed scared at first but calmed down after about 30 minutes. So overall, this is a functioning product with little issues. So far, those have both held up, so the non-locking lid has not been an issue.

I really like that it has suction cups, and is very sturdy on the glass. I do suggest leaving the lid above the waterline, however, as it has two holes.

"I'm happy with this."

Lets in just enough new water to keep it clean, but not too much to have a current. Not sure why some people are complaining the the separating tray floats. My kids observe the fish and write notes about health and behavior. Breeder nets are available in many sizes including larger than both boxes. The dividers only work with the fry drop in place. I have both the small and larger version. This product is excellent, works fabulously.

"The problem is."

5 gallon, but he was struggling to swim. We caught momma the day before she had them and removed her after. First one arrived used with gravel and a hole in it. The net is harder to see through but not for the casual observer. My husband got me a few guppies that apparently had been pregnant. I have noticed that with all they pieces in that food does not exit the bottom half. Kind of a pain to remove the lid and feed the fry.

I'll put the bag from the pet shop in it and cut it open. He's happy just sitting on his plant blowing bubbles. 5 gallon, but he was struggling to swim.

I feel like this breeder box is sturdier than some others that I've used. I left it out and the babies were sneaking out through that hole. I really like that it has suction cups, and is very sturdy on the glass. I will definitely buy these kind of breeder again. I never knew how important this was until tank cleaning time! With everything out the tank seems to stay really clean. The funnel tray is placed too high within the box.

"Overall I did like it."

As with many plastics, if it isn't thick enough, then it can break. The suction cups were adequate and held the breeder on to the glass fairly well. They seemed scared at first but calmed down after about 30 minutes. It's unsightly with big uneven seams and extra fabric. The Petzilla and Lee's make observations easier. I ordered this and it came next day. It's a decent size for an internal breeder box.

I also like to put in a bowl with acclimating. I got this so I can just put him in our 20-gallon hex with the angelfish. This product is good for the price. I've used several other floating breeders, and have always wished they were larger. So it IS possible for very small fry to slip through the slits. I didn't have the space for an external one. If that bottom piece fit better it would have been perfect.

"Assembly was fine."

I'll put the bag from the pet shop in it and cut it open. We had 2 pregnant fish in seperate halves with them seperated. I gave 4 stars becauses the mesh gets algae ridden pretty easily and stained green. It is large enough for fish bigger than guppies. It's a decent size for an internal breeder box. I put the rainbar into it so now they can't escape. This keeps her area better airated and actually helps flow the babies out.

"I'm happy with this."

The breeder box has a decent size for isolating fish or dwarf shrimp. There's only one issue with this unit. Easily accommodates two Molly's, swords or platy fish. They are now all back together, living as peaceably as fish can. It comes with 2 suction cups for when you want it to stay in place. The lid doesn't lock in place too snugly which make it easy to open. Instead of catching babies, I simply leave the mom in the top piece.
