"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.

"Works pretty well."

My betta fish even got in fights 3 times because the went through them. The fry didn't understand so they swam through the sides. This worked perfectly for my 55 gallon aquarium. I actually like how tight it fits so it won't get dislocated accidentally. It comes with MANY suction cups and attachments. I'm separating male and female cichlids. If you have the divider in the gravel it will not meet the top of the tank.

"They don't snap together."

Let's water flow freely through our entire tank. I created an inexpensive portable indoor potty for my little dog. I would much rather be able to see my whole tank the rest of the day. Product works great if you can figure out how to fit it into your fish tank. Holes are drilled evenly and it will divide fish 1. Holes are big enough for good circulation throughout the tank. I uploaded a video to demonstrate the barrier in action xD.

"Works well."

The gravel along with the quick trim left no gaps for me. It worked well in my very small 12 gallon show tank. I got this to keep my albino Koi guppies separated from my fancy males. My only small issue with it is the way it attaches to the tank. I mean, it's an aquarium divider lol. Holes are big enough for good circulation throughout the tank. Look closely at the slight taper in the connections to see which way to insert them.

"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. And if you fill your tank very full with water they can swim over the divider.

"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.

"What I expected."

The flow holes allowed for ample current and water circulation. First- When dividing a 10 gallon tank the flow is not the same. It dose have good flow between the tanks. This product is one that I would be really sad to see disappear. I did have to bury the bottom in about an inch or so of gravel to keep it in place. This fit PERFECTLY in our 75 gallon aquarium. The fry didn't understand so they swam through the sides.

"Great product."

And I've been in the hobby a long time! I turn a 10-gallon tank into three, 3. So if you have the exact tank, it would be perfect. 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. Overall this has done the job I've needed to. A silicone tray, Charcoal potty pad, and this grid.

"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!

And since it has been working ok, I decided to change the review to 4 star. Two were forced to spend most of their time in hiding.

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.

"I tried and tried."

You just need to peel of the protective layer from both sides. This worked perfectly for my 55 gallon aquarium. Works wonders for our water turtle tank. You can customize the to whichever size you like and the suctions are great. Im using them to hold airline tubing. I know Betta fish are aggressive, so they must be separated. I used this to separate my two Betta fish in a 10 gallon tank.

You will need fingernails to peel them. Don't think so, unless it’s not in water. I turn a 10-gallon tank into three, 3. They can see each other but they can't fight.

"And transparent."

It comes in clear so I had to rough up both sides to make it opaque. It is a bit tricky to straighten it and clip it, but with a bit of a push, it's fine. For platty fry I reccomend the Petzilla Aquarium Fish Breeder box. Small, skinny betta can go through those. I cut it to size using a paper cutter because it was easier than scissors. And I've been in the hobby a long time! I've bought several of these to divide my betta's and they've been great!

"Also looks well."

I came back to give it a 4 star review! The first time we tried using this, we cracked an empty one. We have four South American cichlids that do not live in harmony together. Worth it though if you have money to blow. Not sure I would recommend it for fry however. You do have to assemble it yourself but that isn't too hard. It is easy to install but, careful not to lose anything.
