"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.

The only con is that it's see through. Easy to use and perfect for my tank! Not worried about the small fish due to the size of the fry. This product is one that I would be really sad to see disappear. I personally only want to put the separator in for just feeding time. My male bettas could see each other along the top of the divider. Take it from us— follow the instructions about what type to use!

"Works pretty well."

It is a thick sturdy plastic, and the suction power is strong. That was another battle trying to get those on. The product comes with many small plastic pieces. Works great and we have it holding a divider in a lizard tank. Fish can't swim to the other side anymore, and it looks super cool. Holes are drilled evenly and it will divide fish 1. Second- Do not recommend for bettas or small fish!

"A+ in my book!"

I know Betta fish are aggressive, so they must be separated. And now I know they are getting enough to eat. The divider itself works very well and seems sturdy. It was a bit too wide for my tank, so I cut it a bit and it's perfect. It dose have good flow between the tanks. Got it for my bettas fish,male and female. I have to trim off about a quarter inch and then they work just fine.

"It's fairly easy to do."

Small, skinny betta can go through those. No it doesnt come with the suction cups. I uploaded a video to demonstrate the barrier in action xD. The first time we tried using this, we cracked an empty one. You need to use a mallet to connect the panels together. I had an oddly aggressive Molly and this worked great for the time I needed to use. You just need to peel of the protective layer from both sides.

"Otherwise very good."

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. It comes with MANY suction cups and attachments.

  • Size and Material: segregation board 11.8x6x0.25inch, grid size 0.39x0.39 inch, suction cup 2.6x2.2inch, fix for about 6mm thickness tray, they are all made of plastic material.

  • Tip: When clamping your separating plate with suction cup, pay attention to the angle of jamming. First hold the plate at a 45-degree angle to the side of the plate, do not use brute force, and then slowly fix the remaining part.

YG_Oline Final Thoughts

"Made a shelf in my sump."

I'm not using it but keeping it in case. Two were forced to spend most of their time in hiding. You do have to assemble it yourself but that isn't too hard. And I've been in the hobby a long time! I did have to bury the bottom in about an inch or so of gravel to keep it in place. You can also try any other small fish. Description says if they dont go together use zip ties.

"Excellent product!"

I can see why people thought it was white. Purchased this to temporarily divide a 20-long tank for axolotls. Holes are drilled evenly and it will divide fish 1. Make sure you read the instructions and have the right type of aquarium! The divider itself works very well and seems sturdy. The holes are smaller than some other similar dividers, which is why I chose these. I know Betta fish are aggressive, so they must be separated.

This is THE BEST divider I've found! The connection joints are very snug. The product comes with many small plastic pieces. My dog can use her indoor potty and keep clean and dry above the pad. They look like the edging that's on the tanks, so it's as attractive as possible. Overall this has done the job I've needed to. It comes in clear so I had to rough up both sides to make it opaque.

"The divider works well."

I actually like how tight it fits so it won't get dislocated accidentally. Two were forced to spend most of their time in hiding. This WILL fit an Aqueon tall 10 gallon, but NOT a Top Fin tall 10 gallon. It is thick, well made and a great addition if you have the tank they specified. This is THE BEST divider I've found! Works wonders for our water turtle tank. My dog can use her indoor potty and keep clean and dry above the pad.

"Go together easy."

It comes in clear so I had to rough up both sides to make it opaque. Very pleased with this tank divider. Giving it 4 stars due to the high price of something so simple. Purchased this to temporarily divide a 20-long tank for axolotls. There are slots along the top that they can see through. Doesn't obstruct the look of my fish tank. The only con is that it's see through.

Perfect fit, easy to install, and ideal design. The divider itself works very well and seems sturdy. I bought these clear suction cups separately. You need to use a mallet to connect the panels together. I will be buying more of this I recommend them 100%. If you have the divider in the gravel it will not meet the top of the tank. This product is one that I would be really sad to see disappear.

"Also looks well."

It's good for what I needed it for. No matter what size betta I put I know it won't go through the divider. I would much rather be able to see my whole tank the rest of the day. Third- pull the divider all the way up. Make sure to set it up in the middle of the water pump. I came back to give it a 4 star review! So I dont need the suction cups even though I'm glad I have them.

Get this if your dividing your tank for betta fish. They can see each other but they can't fight. My dog can use her indoor potty and keep clean and dry above the pad. I bought these clear suction cups separately. This WILL fit an Aqueon tall 10 gallon, but NOT a Top Fin tall 10 gallon. Don't think so, unless it’s not in water. Actually adds additional filtration I think.

"Worked like a charm."

First- When dividing a 10 gallon tank the flow is not the same. Take it from us— follow the instructions about what type to use! The fry didn't understand so they swam through the sides. You will have to cut them to fit any other size aquarium. Let's water flow freely through our entire tank. It was slightly long so I had to trim off the bottom edge to make it fit. I had ordered 3 others before this one.
