"They don't snap together."

And now I know they are getting enough to eat. We have four South American cichlids that do not live in harmony together. It keeps the boys from being able to see each other. 4stars because it says easy to connect peices together. It worked well in my very small 12 gallon show tank. Very good divider for my 20 gal long freshwater aquarium. Barrier is like a plastic mesh screen that allows water to flow through.

Yohii Final Thoughts

"Excellent product!"

I turn a 10-gallon tank into three, 3. They can see each other but they can't fight. I also found out small fish can easily swim between the gaps on the sides. I did have to bury the bottom in about an inch or so of gravel to keep it in place. You need to use a mallet to connect the panels together. You just need to peel of the protective layer from both sides. Two were forced to spend most of their time in hiding.

"Simple fix."

I cam keep my 2 betta fish in the same tank now. I had an oddly aggressive Molly and this worked great for the time I needed to use. It worked well for me and I would highly recommend it to anyone. I did not receive suction cups but I had my own to it did what I was looking for. That was another battle trying to get those on. Product works great if you can figure out how to fit it into your fish tank. This product is one that I would be really sad to see disappear.

"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.

  • YG_Oline 5 Pcs Black Aquarium Divider Trays, Plastic Grid Isolate Board Divider, Durable Filter Grid Segregation Board with 15 Pcs Black Sucker Clips for Fish Tank
  • 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.
  • Function: You can easily divide your fish tank into several compartments with these dividers. Use these dividers to separate different fish and breed, so you don’t have to worry about your aquarium fighting anymore
  • 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.
  • You can easily divide your fish tank into several compartments with these compartment holders. This plastic grid can be combined with cutting and free stitching

"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.

"Works great."

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!

"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.

"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!

"Had to go another way."

Description says if they dont go together use zip ties. This is a great option for keeping two bettas in the same tank! I'm not using it but keeping it in case. I'm separating male and female cichlids. Divider works well for our two Bettas that share a 10 gallon aquarium. I turn a 10-gallon tank into three, 3. It is difficult to move the side bars to move out to close the gaps.

"5 gallon fabric pots."

You will have to cut them to fit any other size aquarium. 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. The connection joints are very snug. So I divided it allowing me to have 2 tanks in one large tank. I got this so I could put two male bettas in a tank. And since it has been working ok, I decided to change the review to 4 star.

"But it keeps adults in."

Make sure to set it up in the middle of the water pump. Very few problems just a couple things to keep in mind when buying. There are slots along the top that they can see through. This product is one that I would be really sad to see disappear. There were scratches when we got this so I originally gave it one star review. The divider itself works very well and seems sturdy.

"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.
