"The choice is yours!"

My only small issue with it is the way it attaches to the tank. The fry didn't understand so they swam through the sides. The flow holes allowed for ample current and water circulation. It is easy to install but, careful not to lose anything. Overall I was pleased with this divider. First- When dividing a 10 gallon tank the flow is not the same. Will certainly be buying more of these!

"So I tried and tried."

You can customize the to whichever size you like and the suctions are great. Holes are drilled evenly and it will divide fish 1. I came back to give it a 4 star review! Barrier is like a plastic mesh screen that allows water to flow through. It is thick, well made and a great addition if you have the tank they specified. It comes in clear so I had to rough up both sides to make it opaque. Not sure I would recommend it for fry however.

Very pleased with this tank divider. Overall this has done the job I've needed to. Second- Do not recommend for bettas or small fish! I mean, it's an aquarium divider lol. I've bought several of these to divide my betta's and they've been great! I cut it to size using a paper cutter because it was easier than scissors. It's good for what I needed it for.

"Sold separately."

That was another battle trying to get those on. Works great and we have it holding a divider in a lizard tank. Barrier is like a plastic mesh screen that allows water to flow through. That was another battle trying to get those on. Two were forced to spend most of their time in hiding. I turn a 10-gallon tank into three, 3. You will need fingernails to peel them.

"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.

"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.

"Kept fish apart."

I got this to keep my albino Koi guppies separated from my fancy males. The product comes with many small plastic pieces. It was a bit too wide for my tank, so I cut it a bit and it's perfect. Works great and we have it holding a divider in a lizard tank. I did have to bury the bottom in about an inch or so of gravel to keep it in place. I would much rather be able to see my whole tank the rest of the day. The product comes with many small plastic pieces.

"I love this!"

It assembled quickly and painlessly. And if you fill your tank very full with water they can swim over the divider. You will have to cut them to fit any other size aquarium. There are slots along the top that they can see through. I got this so I could put two male bettas in a tank. Description says if they dont go together use zip ties. Third- pull the divider all the way up.

"Becomes a bit cloudy."

Small, skinny betta can go through those. It is a thick sturdy plastic, and the suction power is strong. The connection joints are very snug. Make sure you read the instructions and have the right type of aquarium! The only con is that it's see through. I bought these clear suction cups separately. Got it for my bettas fish,male and female.

Balacoo 1939ZQPO6182MH6 Final Thoughts

"Hopefully."

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. If you have the divider in the gravel it will not meet the top of the tank. You will have to cut them to fit any other size aquarium. I had an oddly aggressive Molly and this worked great for the time I needed to use. Only for betta fish since I own them. My betta fish even got in fights 3 times because the went through them.

"Works as intended!"

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.

Very tight fit with hardly any gap. No it doesnt come with the suction cups. This fit PERFECTLY in our 75 gallon aquarium. It assembled quickly and painlessly. You do have to assemble it yourself but that isn't too hard. The holes are smaller than some other similar dividers, which is why I chose these. My male bettas could see each other along the top of the divider.

"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.

"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.
