"Good price."

My only small issue with it is the way it attaches to the tank. And if you fill your tank very full with water they can swim over the divider. I am going to put a Male betta on each side. Get this if your dividing your tank for betta fish. You can also try any other small fish. It is easy to install but, careful not to lose anything. There are slots along the top that they can see through.

  • Handy clips to divide a bigger fish tank into several compartment for breeding or separation.

MECO Final Thoughts

"Thank you!"

The holes are smaller than some other similar dividers, which is why I chose these. They look like the edging that's on the tanks, so it's as attractive as possible. I bought these clear suction cups separately. I'm not using it but keeping it in case. Third- pull the divider all the way up. I turn a 10-gallon tank into three, 3. Overall I was pleased with this divider.

2. Aliyaduo 8 Pack Fish Tank Divider, Snap Together & Cutting Feature - Plastic Aquarium Divider Panel ...

"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.

"We'll see."

I know Betta fish are aggressive, so they must be separated. It comes in clear so I had to rough up both sides to make it opaque. This was clear, easy to install, and well made. It is a bit tricky to straighten it and clip it, but with a bit of a push, it's fine. I did not receive suction cups but I had my own to it did what I was looking for. I used this product to divide my 10gallon tank. The product comes with many small plastic pieces.

"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.

"Hope this helped!"

It was a bit too wide for my tank, so I cut it a bit and it's perfect. No it doesnt come with the suction cups. Got it for my bettas fish,male and female. However, keep in mind this tank divider does not fit just ANY 10 gallon! The divider itself works very well and seems sturdy. I got this so I could put two male bettas in a tank. They can see each other but they can't fight.

"Let's face it."

Get this if your dividing your tank for betta fish. Overall I was pleased with this divider. Make sure you read the instructions and have the right type of aquarium! If you have the divider in the gravel it will not meet the top of the tank. Holes are big enough for good circulation throughout the tank. And since it has been working ok, I decided to change the review to 4 star. Very pleased with this tank divider.

I actually like how tight it fits so it won't get dislocated accidentally. Works great and we have it holding a divider in a lizard tank. I created an inexpensive portable indoor potty for my little dog. This is THE BEST divider I've found! Not worried about the small fish due to the size of the fry.

"They are plastic grids."

Only reason I took a star off was the price. The holes are smaller than some other similar dividers, which is why I chose these. Third- pull the divider all the way up. I would much rather be able to see my whole tank the rest of the day. Will certainly be buying more of these! You will have to cut them to fit any other size aquarium. I came back to give it a 4 star review!

"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.

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.

"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.
