"Perfect height."

My dog can use her indoor potty and keep clean and dry above the pad. Not sure I would recommend it for fry however. I used this product to divide my 10gallon tank. It comes in clear so I had to rough up both sides to make it opaque. Would recommend two smaller filters on either side to help water flow. Description says if they dont go together use zip ties. Perfect fit, easy to install, and ideal design.

  • WEAVERBIRD 2 Pcs Aquarium Divider Tray Plastic Grid Divider Tray Egg Crate for Aquarium Fish Tank Bottom Isolation
  • Isolation plate material: high-quality plastic material, suitable for fresh water and seawater, will not affect water quality. The fish are effectively separated to prevent the fish from biting each other, and can also be used as a filter at the bottom of the fish tank.
  • Base plate size: 11.6"x 5.82"x 0.27"(29.5x14.8x0.7cm), the size of small grid is 0.39''X 0.39'', you can use these divider brackets to easily divide the fish tank into several compartments for breeding or separation.
  • Combination splicing function: The fish tank isolation net can be freely combined and spliced at random to meet the needs of most fish tanks. Generally it can be used as isolation fish or placed on the bottom of the fish tank as a bedding isolation plate to isolate the filter material and make the water flow smoothly.
  • Easy to use: The grid divider can be cut and spliced, and the clip can be fixed anywhere in the aquarium, making it more convenient to use. It is usually used to isolate fish schools; build platforms for fish tanks; filter at the bottom; isolate filter materials.

WEAVERBIRD Final Thoughts

"And worth every penny!"

I'm not using it but keeping it in case. Look closely at the slight taper in the connections to see which way to insert them. It is thick, well made and a great addition if you have the tank they specified. Only because of that reviewer, I was able to use them the way I intended. This product is one that I would be really sad to see disappear. So I'm writing this to tell you you step on them. You will need fingernails to peel them.

"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.

I can see why people thought it was white. The product comes with many small plastic pieces. That was another battle trying to get those on. The divider itself works very well and seems sturdy.

BILLIOTEAM Final Thoughts

"So dont assume they do."

It's great products, fit perfectly and fast shipping. It comes in clear so I had to rough up both sides to make it opaque. This WILL fit an Aqueon tall 10 gallon, but NOT a Top Fin tall 10 gallon. It is difficult to move the side bars to move out to close the gaps. I know Betta fish are aggressive, so they must be separated. You will have to cut them to fit any other size aquarium. The only con is that it's see through.

"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.

"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.

4stars because it says easy to connect peices together. Doing these two things really keeps this thing in place. You need to use a mallet to connect the panels together.

User Ratings: 65 3

"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.

"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.

"Works great."

My dog can use her indoor potty and keep clean and dry above the pad. I will be buying more of this I recommend them 100%. The only con is that it's see through. It was a bit too wide for my tank, so I cut it a bit and it's perfect. However, it was easy to install and it worked pretty well in the last few weeks. Didn't ruin the look of the tank nor interfere with tank filter system. Fish can't swim to the other side anymore, and it looks super cool.

I'm separating male and female cichlids. I know Betta fish are aggressive, so they must be separated. Description says if they dont go together use zip ties.

"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!

"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.
