"Otherwise very good."

You can customize the to whichever size you like and the suctions are great. I have to trim off about a quarter inch and then they work just fine. Nice, thick and attractive divider. They can still see each other and try to fight through the barrier but its a no go. Barrier is like a plastic mesh screen that allows water to flow through. So I divided it allowing me to have 2 tanks in one large tank. I mean, it's an aquarium divider lol.

"However, I bought the 15."

It's great products, fit perfectly and fast shipping. Very tight fit with hardly any gap. My dog can use her indoor potty and keep clean and dry above the pad. It assembled quickly and painlessly. This fit PERFECTLY in our 75 gallon aquarium. Look closely at the slight taper in the connections to see which way to insert them. Small, skinny betta can go through those.

"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.

"The divider works well."

I actually like how tight it fits so it won't get dislocated accidentally. Two were forced to spend most of their time in hiding. This WILL fit an Aqueon tall 10 gallon, but NOT a Top Fin tall 10 gallon. It is thick, well made and a great addition if you have the tank they specified. This is THE BEST divider I've found! Works wonders for our water turtle tank. My dog can use her indoor potty and keep clean and dry above the pad.

"We'll see."

I know Betta fish are aggressive, so they must be separated. It comes in clear so I had to rough up both sides to make it opaque. This was clear, easy to install, and well made. It is a bit tricky to straighten it and clip it, but with a bit of a push, it's fine. I did not receive suction cups but I had my own to it did what I was looking for. I used this product to divide my 10gallon tank. The product comes with many small plastic pieces.

"Excellent product!"

They can still see each other and try to fight through the barrier but its a no go. So if you have the exact tank, it would be perfect. There were scratches when we got this so I originally gave it one star review. I got this to keep my albino Koi guppies separated from my fancy males. Take it from us— follow the instructions about what type to use! You can also try any other small fish. It is easy to install but, careful not to lose anything.

"The divider works well."

A silicone tray, Charcoal potty pad, and this grid. I found these and now have 6 of them for my male bettas. I cam keep my 2 betta fish in the same tank now. Make sure you read the instructions and have the right type of aquarium! Holes are drilled evenly and it will divide fish 1. It is a bit tricky to straighten it and clip it, but with a bit of a push, it's fine. 6-25-19- I had to make a minor adjustment to my divider.

"Love these!"

Only reason I took a star off was the price. You can also try any other small fish. Doesn't obstruct the look of my fish tank. We have four South American cichlids that do not live in harmony together. I also found out small fish can easily swim between the gaps on the sides. So I dont need the suction cups even though I'm glad I have them. I turn a 10-gallon tank into three, 3.

"They were all awful!"

You will need fingernails to peel them. I used this product to divide my 10gallon tank. Easy to use and perfect for my tank! You can also cut it down to the size of your tank, which was not too difficult to do. I cam keep my 2 betta fish in the same tank now. This product is one that I would be really sad to see disappear. If you have the divider in the gravel it will not meet the top of the tank.

"Worked perfectly."

You need to use a mallet to connect the panels together. I personally only want to put the separator in for just feeding time. I actually like how tight it fits so it won't get dislocated accidentally. It is thick, well made and a great addition if you have the tank they specified. You need to use a mallet to connect the panels together. For platty fry I reccomend the Petzilla Aquarium Fish Breeder box. This WILL fit an Aqueon tall 10 gallon, but NOT a Top Fin tall 10 gallon.

"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.

"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.

"Had to go another way."

Description says if they dont go together use zip ties. This is a great option for keeping two bettas in the same tank! I'm not using it but keeping it in case. I'm separating male and female cichlids. Divider works well for our two Bettas that share a 10 gallon aquarium. I turn a 10-gallon tank into three, 3. It is difficult to move the side bars to move out to close the gaps.
