"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.

"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.

"So it's nice decision."

I have to trim off about a quarter inch and then they work just fine. It worked well for me and I would highly recommend it to anyone. 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. Small, skinny betta can go through those. They can still see each other and try to fight through the barrier but its a no go. Very good divider for my 20 gal long freshwater aquarium.

• FLEXIBLE TO USE - each Fish Tank Divider can be snapped together to make a large panel, also can be cut easily with wire cutter to your desired size to fit your fish tank
• EASY TO INSTALL - just slip the male into the female by placing one above the other and pushing down. You can't push horizontally. If you can not get these grids to connect together, zip ties also recommended
• VERSATILE DIVIDERS - the fish tank partitions can be used to separate a fish that had started getting too aggressive, to elevate rocks in an Aquascape as a base level in the aquarium, to make turtle ramps for your turtle habitats, or do some other diy projects. Limitless possibilities for what these can be used for
• DIENESIONS - each aquarium divider piece measures approx 30cm * 15cm/ 11.81 * 5.91 inch(L*W), each grid hole measures approx 1cm/0.4 inch, which is small enough that your betta fish wouldn't get through or get stuck.

And I've been in the hobby a long time! I can see why people thought it was white. The female is on the larger side with her babies. It was a bit too wide for my tank, so I cut it a bit and it's perfect. And since it has been working ok, I decided to change the review to 4 star. Don't think so, unless it’s not in water.

"Excellent product!"

Second- Do not recommend for bettas or small fish! It worked well in my very small 12 gallon show tank. Only because of that reviewer, I was able to use them the way I intended. If you have the divider in the gravel it will not meet the top of the tank. It was a bit too wide for my tank, so I cut it a bit and it's perfect. Only reason I took a star off was the price. Make sure you read the instructions and have the right type of aquarium!

"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.

"It's fairly easy to do."

It dose have good flow between the tanks. And if you fill your tank very full with water they can swim over the divider. I would much rather be able to see my whole tank the rest of the day. The connection joints are very snug. Two were forced to spend most of their time in hiding. I bought these clear suction cups separately. It keeps the boys from being able to see each other.
