"Love this seat cover."

The holes are smaller than some other similar dividers, which is why I chose these. It was a bit too wide for my tank, so I cut it a bit and it's perfect. Overall this has done the job I've needed to. It is a thick sturdy plastic, and the suction power is strong. The female is on the larger side with her babies. It's good for what I needed it for. I have it in a divided ten gallon with two bettas.

Gelible Final Thoughts

"But it keeps adults in."

I got this so I could put two male bettas in a tank. It comes in clear so I had to rough up both sides to make it opaque. Im using them to hold airline tubing. So I divided it allowing me to have 2 tanks in one large tank. 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! This product is one that I would be really sad to see disappear.

"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.

"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!

"Cut to fit snug."

You can also try any other small fish. I found these and now have 6 of them for my male bettas. Fish can't swim to the other side anymore, and it looks super cool. I have it in a divided ten gallon with two bettas. They can still see each other and try to fight through the barrier but its a no go. Very few problems just a couple things to keep in mind when buying. I have to trim off about a quarter inch and then they work just fine.

"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.

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.

"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.

My betta fish even got in fights 3 times because the went through them. You do have to assemble it yourself but that isn't too hard. I actually like how tight it fits so it won't get dislocated accidentally. Very pleased with this tank divider. I mean, it's an aquarium divider lol.

"I tried and tried."

It is a bit tricky to straighten it and clip it, but with a bit of a push, it's fine. Would recommend two smaller filters on either side to help water flow. Even though there are holes in the acrylic the water flow is not the same. It worked well for me and I would highly recommend it to anyone. I mean, it's an aquarium divider lol. 4stars because it says easy to connect peices together. I came back to give it a 4 star review!

The first time we tried using this, we cracked an empty one. My only small issue with it is the way it attaches to the tank. My dog can use her indoor potty and keep clean and dry above the pad. Very tight fit with hardly any gap. Works great and we have it holding a divider in a lizard tank. Make sure to set it up in the middle of the water pump. Would recommend two smaller filters on either side to help water flow.

My only small issue with it is the way it attaches to the tank. 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. This WILL fit an Aqueon tall 10 gallon, but NOT a Top Fin tall 10 gallon. Make sure it is tight and smooth on the sides of the tank. Im using them to hold airline tubing.
