I have it in a divided ten gallon with two bettas. Purchased this to temporarily divide a 20-long tank for axolotls. Second- Do not recommend for bettas or small fish! Barrier is like a plastic mesh screen that allows water to flow through. Giving it 4 stars due to the high price of something so simple.

LQ Industrial Final Thoughts

"Thank you!"

Worth it though if you have money to blow. It's great products, fit perfectly and fast shipping. Very good divider for my 20 gal long freshwater aquarium. 6-25-19- I had to make a minor adjustment to my divider. They can still see each other and try to fight through the barrier but its a no go. It comes with MANY suction cups and attachments. It comes in clear so I had to rough up both sides to make it opaque.

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.

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.

"So it's nice decision."

This are black in they stick to the tank not like glue or anything lol. Very tight fit with hardly any gap. Two were forced to spend most of their time in hiding. I'm separating male and female cichlids. Very good divider for my 20 gal long freshwater aquarium. It is thick, well made and a great addition if you have the tank they specified. Very tight fit with hardly any gap.

"Excellent product!"

The gravel along with the quick trim left no gaps for me. This is a great option for keeping two bettas in the same tank! I used this to separate my two Betta fish in a 10 gallon tank. They can still see each other and try to fight through the barrier but its a no go. It is a thick sturdy plastic, and the suction power is strong. It dose have good flow between the tanks. No it doesnt come with the suction cups.

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.

"Works great."

My betta fish even got in fights 3 times because the went through them. You do have to assemble it yourself but that isn't too hard. I actually like how tight it fits so it won't get dislocated accidentally. Very pleased with this tank divider. I mean, it's an aquarium divider lol.

"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.

You do have to assemble it yourself but that isn't too hard. Product works great if you can figure out how to fit it into your fish tank. Two were forced to spend most of their time in hiding. So I divided it allowing me to have 2 tanks in one large tank. It comes in clear so I had to rough up both sides to make it opaque. 6-25-19- I had to make a minor adjustment to my divider. I created an inexpensive portable indoor potty for my little dog.

Overall I was pleased with this divider. Only reason I took a star off was the price. I also found out small fish can easily swim between the gaps on the sides. You can customize the to whichever size you like and the suctions are great. Look closely at the slight taper in the connections to see which way to insert them. Overall this has done the job I've needed to. Very tight fit with hardly any gap.
