Wish I would have noticed the dimensions of this item-pretty small, even for a momma guppy.

This has worked perfectly for us! I did read reviews first. Lots of them and they are very accurate. The large is VERY SMALL. if you are using this to catch the babies when the mom is birthing them I would say this is only good for fish around the size of guppies, platties or mollies. It is extremely small. I woke up and saw babies in my tank and ordered this with same day delivery. I caught them and put them in here so the mom was never in here. I did put gravel in the bottom as suggested in one other review and I also put some java moss in to help them hide and feel safe. I'm very pleased with it. For me the size is perfect but if you have a larger fish and you're breeding on a regular basis this probably is not something you dont want to purchase. This is in my 65 Gallon tank. I gave it 4 stars because of size. I can't imagine what the small one looks like. To me I would consider this a small if I'm thinking about small, med and Lg sizes.

I tried this out for my guppies and it worked perfect!! The babies aren’t so small they can escape through the holes but it’s big enough for them to be in temporarily. Do make sure you understand the measurements though because the small box is pretty small! But no complaints I love mine!

Pros: The section cups attach to your aquarium and the unit stays put. It is more attractive then the netted breeding boxes, it doesnt collect food particles and make your tank look dirty.Cons: I was very disappointed in the size. It is VERY small. I put a tetra in it and immediately took her out. I felt so bad, she had absolutely no room. She even appeared uncomfortable and stressed. The divider kept floating up and it was hard to finally get it to stay put.All in all it was a decent product for the price, however, I am not real sure of a fish (even a tiny guppy) that would comfortably fit and enjoy being in this breeding unit.

This is built for larger fish breeding and fry nursery, not for anything smaller. I used this for my pregnant ghost shrimp and unfortunately, lost majority of fry through the vents (saw one floating off to his death..). I had to use plastic wrap to carefully create the barrier and managed to save one fry.. and yes, I got small size breeder box. The vents may be too big for certain type of fry so buyer beware.Update: My Neon Black tetras were swimming wildly in my tank and I recognized the signs, so placed my pregnant female in this box then most active male that was stalking her and wanting to get in got his wish. Within minutes after being acclimated, they were rubbing against each other and female was laying lots of eggs....but once again, the VENT IS TOO BIG!! The majority of the eggs were flying off through the vents and eagerly awaiting tetras were well fed. Few eggs survived that didn't fall through the vent, but I HIGHLY RECOMMEND anyone else to get something beside this garbage. I'm pretty sure the fry will not remain long here sine they'll be swimming out through the vents just like my ghost shrimp fry.

Perfect size and worked great for what I needed it for. My snails laid eggs so I wanted to try saving some. The babies fell right in and are growing big and strong! Fish can’t eat them! 🥰

I purchase this box because I knew I had two fish who were going to give birth soon. I put the mothers in one tank and had this one for the nursery because of its small size. But the suction cups would not hold onto the side of the tank. They kept releasing no matter how hard we push to hold on. The first night the nursery was full, the box pulled away from the side sometime during the night and floated under the waterfall in the tank. The waterfall caused the tank to sink and in the morning all the babies were gone. We searched the tank for the baby fish and decided they had become live fish food for the other fish.Beware of the the suction cups. They are not strong enough or reliable enough to hold the box to the tank wall.
Beautiful & reliable

This is quite small. Note the measurements before ordering. Ok for what I needed. Plastic is thin. The suction cups work fine.

Great for a little fish to be in there, but I found it too small. I can barely put my hand inside to grab the divider out.One of my question before purchase is that, would the new born fish escape the breeder box from those vertical gaps. The answer was absolutely they DO NOT escape.I also wished the suction cups wasn't back but in clear.When i have two female guppies in there, the bigger will chase the smaller one, so I might have to upgrade to two side breeder.

It worked well to separate the fry fron the mamas, but the slits are just too big and lost 3/4 of the fry to a clever loach that managed to snag them through the slits. I put the thin plastic sheet at the bottom and that helped a bit, but the loach still managed to snag 4 or 6 more through the side slits.
