"The tank is only 7."

The female is on the larger side with her babies. This is THE BEST divider I've found! Description says if they dont go together use zip ties. There were scratches when we got this so I originally gave it one star review. Second- Do not recommend for bettas or small fish! I'm separating male and female cichlids. The gravel along with the quick trim left no gaps for me.

"Sticks on glass."

For platty fry I reccomend the Petzilla Aquarium Fish Breeder box. The divider itself works very well and seems sturdy. Actually adds additional filtration I think. You just need to peel of the protective layer from both sides. Very few problems just a couple things to keep in mind when buying. I uploaded a video to demonstrate the barrier in action xD. Worth it though if you have money to blow.

"Great water flow."

Even though there are holes in the acrylic the water flow is not the same. It is a bit tricky to straighten it and clip it, but with a bit of a push, it's fine. So I'm writing this to tell you you step on them. Look closely at the slight taper in the connections to see which way to insert them. I also found out small fish can easily swim between the gaps on the sides. They can see each other but they can't fight. I found these and now have 6 of them for my male bettas.

"Works as intended!"

6-25-19- I had to make a minor adjustment to my divider. I cam keep my 2 betta fish in the same tank now. We have four South American cichlids that do not live in harmony together. I personally only want to put the separator in for just feeding time. Holes are big enough for good circulation throughout the tank. It was slightly long so I had to trim off the bottom edge to make it fit. 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. I did have to bury the bottom in about an inch or so of gravel to keep it in place. Doesn't obstruct the look of my fish tank.

"Perfect egg tray."

First- When dividing a 10 gallon tank the flow is not the same. I mean, it's an aquarium divider lol. I also found out small fish can easily swim between the gaps on the sides. The gravel along with the quick trim left no gaps for me. My betta fish even got in fights 3 times because the went through them. 6-25-19- I had to make a minor adjustment to my divider. Let's water flow freely through our entire tank.

"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.

"I think these are great."

It is thick, well made and a great addition if you have the tank they specified. I would much rather be able to see my whole tank the rest of the day. It is easy to install but, careful not to lose anything. Perfect fit, easy to install, and ideal design. I'll keep it for separating parts of my tank as I plant new areas but not for fry. You can customize the to whichever size you like and the suctions are great. Not sure I would recommend it for fry however.

"Easy to put in tank."

Very pleased with this tank divider. Fish can't swim to the other side anymore, and it looks super cool. I got this to keep my albino Koi guppies separated from my fancy males. Easy to use and perfect for my tank! Don't think so, unless it’s not in water. I would much rather be able to see my whole tank the rest of the day. There are slots along the top that they can see through.

"Very happy with purchase."

It was a bit too wide for my tank, so I cut it a bit and it's perfect. My dog can use her indoor potty and keep clean and dry above the pad. Divider works well for our two Bettas that share a 10 gallon aquarium. I did not receive suction cups but I had my own to it did what I was looking for. Not sure I would recommend it for fry however. And I've been in the hobby a long time! The female is on the larger side with her babies.

"The choice is yours!"

And I've been in the hobby a long time! You will need fingernails to peel them. However, it was easy to install and it worked pretty well in the last few weeks. Doing these two things really keeps this thing in place. I got this so I could put two male bettas in a tank. I used this to separate my two Betta fish in a 10 gallon tank. They look like the edging that's on the tanks, so it's as attractive as possible.

"I effing love it."

It is difficult to move the side bars to move out to close the gaps. Product works great if you can figure out how to fit it into your fish tank. It comes in clear so I had to rough up both sides to make it opaque. Two were forced to spend most of their time in hiding. I also found out small fish can easily swim between the gaps on the sides. The only con is that it's see through. No matter what size betta I put I know it won't go through the divider.

I have it in a divided ten gallon with two bettas. You do have to assemble it yourself but that isn't too hard. No it doesnt come with the suction cups. This is THE BEST divider I've found! It is thick, well made and a great addition if you have the tank they specified. This fit PERFECTLY in our 75 gallon aquarium. No matter what size betta I put I know it won't go through the divider.

"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.

  • Aliyaduo 8 Pack Fish Tank Divider, Snap Together & Cutting Feature - Plastic Aquarium Divider Panel Separator - Grid Isolation Board Divider, Egg Crate Fish Tank Bottom Tray
  • 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.
  • MATERIAL - These fish tank separators are made of food-grade durable plastic material, non-toxic and tasteless, environmental protection won't affect water quality, suitable for both salt water and freshwater tank

"Its very pretty too."

Will certainly be buying more of these! I will be buying more of this I recommend them 100%. I turn a 10-gallon tank into three, 3. I've bought several of these to divide my betta's and they've been great! Works wonders for our water turtle tank. Barrier is like a plastic mesh screen that allows water to flow through. My only small issue with it is the way it attaches to the tank.

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.

"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.
