"We'll see."

I have it in a divided ten gallon with two bettas. Works great and we have it holding a divider in a lizard tank. My betta fish even got in fights 3 times because the went through them. I will be buying more of this I recommend them 100%. It is a thick sturdy plastic, and the suction power is strong. Very pleased with this tank divider. I cut it to size using a paper cutter because it was easier than scissors.

"The tank is only 7."

This is THE BEST divider I've found! It comes with MANY suction cups and attachments. It is a thick sturdy plastic, and the suction power is strong. A silicone tray, Charcoal potty pad, and this grid. I used this product to divide my 10gallon tank. The flow holes allowed for ample current and water circulation. The female is on the larger side with her babies.

"Great purchase!"

They look like the edging that's on the tanks, so it's as attractive as possible. Very sturdy, has clips on the sides to keep in place. Barrier is like a plastic mesh screen that allows water to flow through. It was slightly long so I had to trim off the bottom edge to make it fit. Doesn't obstruct the look of my fish tank. They look like the edging that's on the tanks, so it's as attractive as possible. Worth it though if you have money to blow.

"I tried and tried."

You just need to peel of the protective layer from both sides. This worked perfectly for my 55 gallon aquarium. Works wonders for our water turtle tank. You can customize the to whichever size you like and the suctions are great. Im using them to hold airline tubing. I know Betta fish are aggressive, so they must be separated. I used this to separate my two Betta fish in a 10 gallon tank.

"Works well."

The gravel along with the quick trim left no gaps for me. It worked well in my very small 12 gallon show tank. I got this to keep my albino Koi guppies separated from my fancy males. My only small issue with it is the way it attaches to the tank. I mean, it's an aquarium divider lol. Holes are big enough for good circulation throughout the tank. Look closely at the slight taper in the connections to see which way to insert them.

"Had to go another way."

Make sure to set it up in the middle of the water pump. They can see each other but they can't fight. My male bettas could see each other along the top of the divider. My only small issue with it is the way it attaches to the tank. I have it in a divided ten gallon with two bettas. I have it in a divided ten gallon with two bettas. And if you fill your tank very full with water they can swim over the divider.

"Works well."

I got this so I could put two male bettas in a tank. I did have to bury the bottom in about an inch or so of gravel to keep it in place. I uploaded a video to demonstrate the barrier in action xD. This fit PERFECTLY in our 75 gallon aquarium. I did have to bury the bottom in about an inch or so of gravel to keep it in place. Very sturdy, has clips on the sides to keep in place. Make sure it is tight and smooth on the sides of the tank.

"Suctions not included."

You do have to assemble it yourself but that isn't too hard. Product works great if you can figure out how to fit it into your fish tank. Two were forced to spend most of their time in hiding. So I divided it allowing me to have 2 tanks in one large tank. It comes in clear so I had to rough up both sides to make it opaque. 6-25-19- I had to make a minor adjustment to my divider. I created an inexpensive portable indoor potty for my little dog.

uxcell a14062000ux0363 First Impressions

"Excellent product!"

I can see why people thought it was white. Purchased this to temporarily divide a 20-long tank for axolotls. Holes are drilled evenly and it will divide fish 1. Make sure you read the instructions and have the right type of aquarium! The divider itself works very well and seems sturdy. The holes are smaller than some other similar dividers, which is why I chose these. I know Betta fish are aggressive, so they must be separated.

"Very sturdy."

The only con is that it's see through. Only for betta fish since I own them. Overall this has done the job I've needed to. The product comes with many small plastic pieces. This product is one that I would be really sad to see disappear. I will be buying more of this I recommend them 100%. Two were forced to spend most of their time in hiding.

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.

"Works pretty well."

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.

"Love this seat cover."

They look like the edging that's on the tanks, so it's as attractive as possible. And now I know they are getting enough to eat. It was slightly long so I had to trim off the bottom edge to make it fit. No matter what size betta I put I know it won't go through the divider. And since it has been working ok, I decided to change the review to 4 star. It keeps the boys from being able to see each other. Divider works well for our two Bettas that share a 10 gallon aquarium.

"Hopefully."

It keeps the boys from being able to see each other. However, keep in mind this tank divider does not fit just ANY 10 gallon! I know Betta fish are aggressive, so they must be separated. Would recommend two smaller filters on either side to help water flow. Actually adds additional filtration I think. The female is on the larger side with her babies. This are black in they stick to the tank not like glue or anything lol.

"Worked like a charm."

First- When dividing a 10 gallon tank the flow is not the same. Take it from us— follow the instructions about what type to use! The fry didn't understand so they swam through the sides. You will have to cut them to fit any other size aquarium. Let's water flow freely through our entire tank. It was slightly long so I had to trim off the bottom edge to make it fit. I had ordered 3 others before this one.

"Definitely not easy."

And since it has been working ok, I decided to change the review to 4 star. Two were forced to spend most of their time in hiding. I had an oddly aggressive Molly and this worked great for the time I needed to use. This is a great option for keeping two bettas in the same tank!

"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.
