"3-gallon tanks."

The holes are smaller than some other similar dividers, which is why I chose these. This product is one that I would be really sad to see disappear. The gravel along with the quick trim left no gaps for me. Overall this has done the job I've needed to. I will be buying more of this I recommend them 100%. Fish can't swim to the other side anymore, and it looks super cool. However, it was easy to install and it worked pretty well in the last few weeks.

"Good divider!"

This was clear, easy to install, and well made. Will certainly be buying more of these! Perfect fit, easy to install, and ideal design. You need to use a mallet to connect the panels together. This worked perfectly for my 55 gallon aquarium. That was another battle trying to get those on. This was clear, easy to install, and well made.

"Great water flow."

Very few problems just a couple things to keep in mind when buying. It assembled quickly and painlessly. This is a great option for keeping two bettas in the same tank! Barrier is like a plastic mesh screen that allows water to flow through. I'm separating male and female cichlids. Two were forced to spend most of their time in hiding. I did not receive suction cups but I had my own to it did what I was looking for.

"They really stick too."

I created an inexpensive portable indoor potty for my little dog. You just need to peel of the protective layer from both sides. They can see each other but they can't fight. You do have to assemble it yourself but that isn't too hard. 6-25-19- I had to make a minor adjustment to my divider. Works wonders for our water turtle tank. Fish can't swim to the other side anymore, and it looks super cool.

"The choice is yours!"

Very pleased with this tank divider. Overall this has done the job I've needed to. Second- Do not recommend for bettas or small fish! I mean, it's an aquarium divider lol. I've bought several of these to divide my betta's and they've been great! I cut it to size using a paper cutter because it was easier than scissors. It's good for what I needed it for.

It is a thick sturdy plastic, and the suction power is strong. My dog can use her indoor potty and keep clean and dry above the pad. Giving it 4 stars due to the high price of something so simple. Very few problems just a couple things to keep in mind when buying. And since it has been working ok, I decided to change the review to 4 star. And now I know they are getting enough to eat. Very pleased with this tank divider.

"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.

"5 gallon fabric pots."

I will be buying more of this I recommend them 100%. Very tight fit with hardly any gap. Purchased this to temporarily divide a 20-long tank for axolotls. Very pleased with this tank divider. Get this if your dividing your tank for betta fish. This WILL fit an Aqueon tall 10 gallon, but NOT a Top Fin tall 10 gallon. I have it in a divided ten gallon with two bettas.

It comes in clear so I had to rough up both sides to make it opaque. Very pleased with this tank divider. Giving it 4 stars due to the high price of something so simple. Purchased this to temporarily divide a 20-long tank for axolotls. There are slots along the top that they can see through. Doesn't obstruct the look of my fish tank.

The holes are smaller than some other similar dividers, which is why I chose these. This is a great option for keeping two bettas in the same tank! Perfect fit, easy to install, and ideal design. I'm not using it but keeping it in case. I did have to bury the bottom in about an inch or so of gravel to keep it in place. It is thick, well made and a great addition if you have the tank they specified. The gravel along with the quick trim left no gaps for me.

"Kept fish apart."

I got this to keep my albino Koi guppies separated from my fancy males. The product comes with many small plastic pieces. It was a bit too wide for my tank, so I cut it a bit and it's perfect. Works great and we have it holding a divider in a lizard tank. I did have to bury the bottom in about an inch or so of gravel to keep it in place. I would much rather be able to see my whole tank the rest of the day. The product comes with many small plastic pieces.

"I love this!"

It assembled quickly and painlessly. And if you fill your tank very full with water they can swim over the divider. You will have to cut them to fit any other size aquarium. There are slots along the top that they can see through. I got this so I could put two male bettas in a tank. Description says if they dont go together use zip ties. Third- pull the divider all the way up.
