"So I tried and tried."

Look closely at the slight taper in the connections to see which way to insert them. The fry didn't understand so they swam through the sides. I had ordered 3 others before this one. Very good divider for my 20 gal long freshwater aquarium. You can also cut it down to the size of your tank, which was not too difficult to do. I know Betta fish are aggressive, so they must be separated. And now I know they are getting enough to eat.

"Worked like a charm."

I uploaded a video to demonstrate the barrier in action xD. Fish can't swim to the other side anymore, and it looks super cool. Doing these two things really keeps this thing in place. Would recommend two smaller filters on either side to help water flow. The holes are smaller than some other similar dividers, which is why I chose these. You can also try any other small fish. Small, skinny betta can go through those.

"The divider works well."

Overall this has done the job I've needed to. I also found out small fish can easily swim between the gaps on the sides. Divider works well for our two Bettas that share a 10 gallon aquarium. And I've been in the hobby a long time! We have four South American cichlids that do not live in harmony together. I created an inexpensive portable indoor potty for my little dog. And I've been in the hobby a long time!

"I like Product."

It keeps the boys from being able to see each other. Only because of that reviewer, I was able to use them the way I intended. I have it in a divided ten gallon with two bettas. You need to use a mallet to connect the panels together. It is easy to install but, careful not to lose anything. The only con is that it's see through. This WILL fit an Aqueon tall 10 gallon, but NOT a Top Fin tall 10 gallon.

"Love this seat cover."

They can see each other but they can't fight. Would recommend two smaller filters on either side to help water flow. Im using them to hold airline tubing. This product is one that I would be really sad to see disappear. It is a bit tricky to straighten it and clip it, but with a bit of a push, it's fine. I actually like how tight it fits so it won't get dislocated accidentally. Giving it 4 stars due to the high price of something so simple.

"Love this seat cover."

The only con is that it's see through. Giving it 4 stars due to the high price of something so simple. Purchased this to temporarily divide a 20-long tank for axolotls. The first time we tried using this, we cracked an empty one. It was a bit too wide for my tank, so I cut it a bit and it's perfect. Doing these two things really keeps this thing in place. It worked well in my very small 12 gallon show tank.

"Works pretty well."

It is a thick sturdy plastic, and the suction power is strong. That was another battle trying to get those on. The product comes with many small plastic pieces. Works great and we have it holding a divider in a lizard tank. Fish can't swim to the other side anymore, and it looks super cool. Holes are drilled evenly and it will divide fish 1. Second- Do not recommend for bettas or small fish!

"And they connected!"

Very tight fit with hardly any gap. No it doesnt come with the suction cups. This fit PERFECTLY in our 75 gallon aquarium. It assembled quickly and painlessly. You do have to assemble it yourself but that isn't too hard. The holes are smaller than some other similar dividers, which is why I chose these. My male bettas could see each other along the top of the divider.

"Works as intended!"

This is THE BEST divider I've found! The connection joints are very snug. The product comes with many small plastic pieces. My dog can use her indoor potty and keep clean and dry above the pad. They look like the edging that's on the tanks, so it's as attractive as possible. Overall this has done the job I've needed to. It comes in clear so I had to rough up both sides to make it opaque.

"Simple fix."

I cam keep my 2 betta fish in the same tank now. I had an oddly aggressive Molly and this worked great for the time I needed to use. It worked well for me and I would highly recommend it to anyone. I did not receive suction cups but I had my own to it did what I was looking for. That was another battle trying to get those on. Product works great if you can figure out how to fit it into your fish tank. This product is one that I would be really sad to see disappear.

"I highly recommend!"

It was a bit too wide for my tank, so I cut it a bit and it's perfect. It dose have good flow between the tanks. Holes are drilled evenly and it will divide fish 1. I'm separating male and female cichlids. There were scratches when we got this so I originally gave it one star review. I had an oddly aggressive Molly and this worked great for the time I needed to use. And if you fill your tank very full with water they can swim over the divider.

"Very carefully machined."

It comes with MANY suction cups and attachments. This WILL fit an Aqueon tall 10 gallon, but NOT a Top Fin tall 10 gallon. I am going to put a Male betta on each side. You can also try any other small fish. Make sure to set it up in the middle of the water pump. A silicone tray, Charcoal potty pad, and this grid.
