"We'll see."

I have it in a divided ten gallon with two bettas. Works great and we have it holding a divider in a lizard tank. My betta fish even got in fights 3 times because the went through them. I will be buying more of this I recommend them 100%. It is a thick sturdy plastic, and the suction power is strong. Very pleased with this tank divider. I cut it to size using a paper cutter because it was easier than scissors.

"The tank is only 7."

This is THE BEST divider I've found! It comes with MANY suction cups and attachments. It is a thick sturdy plastic, and the suction power is strong. A silicone tray, Charcoal potty pad, and this grid. I used this product to divide my 10gallon tank. The flow holes allowed for ample current and water circulation. The female is on the larger side with her babies.

"Love this seat cover."

The holes are smaller than some other similar dividers, which is why I chose these. It was a bit too wide for my tank, so I cut it a bit and it's perfect. Overall this has done the job I've needed to. It is a thick sturdy plastic, and the suction power is strong. The female is on the larger side with her babies. It's good for what I needed it for. I have it in a divided ten gallon with two bettas.

"But it keeps adults in."

I got this so I could put two male bettas in a tank. It comes in clear so I had to rough up both sides to make it opaque. Im using them to hold airline tubing. So I divided it allowing me to have 2 tanks in one large tank. It keeps the boys from being able to see each other. However, keep in mind this tank divider does not fit just ANY 10 gallon! This product is one that I would be really sad to see disappear.

"Works great thank you."

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. My male bettas could see each other along the top of the divider. Holes are drilled evenly and it will divide fish 1. My male bettas could see each other along the top of the divider. It is a thick sturdy plastic, and the suction power is strong.

"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.

Ujuuu First Impressions

"They are plastic grids."

I've bought several of these to divide my betta's and they've been great! Even though there are holes in the acrylic the water flow is not the same. Would recommend two smaller filters on either side to help water flow. There are slots along the top that they can see through. Didn't ruin the look of the tank nor interfere with tank filter system. I had an oddly aggressive Molly and this worked great for the time I needed to use. No matter what size betta I put I know it won't go through the divider.

"3-gallon tanks."

I also found out small fish can easily swim between the gaps on the sides. It keeps the boys from being able to see each other. You can customize the to whichever size you like and the suctions are great. The only con is that it's see through. However, keep in mind this tank divider does not fit just ANY 10 gallon! So if you have the exact tank, it would be perfect. Third- pull the divider all the way up.

"Also looks well."

That was another battle trying to get those on. So I dont need the suction cups even though I'm glad I have them. The flow holes allowed for ample current and water circulation. Let's water flow freely through our entire tank. The female is on the larger side with her babies. It is difficult to move the side bars to move out to close the gaps. It worked well in my very small 12 gallon show tank.

"I like Product."

Only because of that reviewer, I was able to use them the way I intended. There are slots along the top that they can see through. If you have the divider in the gravel it will not meet the top of the tank. Very sturdy, has clips on the sides to keep in place. It dose have good flow between the tanks. This product is one that I would be really sad to see disappear. Look closely at the slight taper in the connections to see which way to insert them.

"Thank you!"

The holes are smaller than some other similar dividers, which is why I chose these. They look like the edging that's on the tanks, so it's as attractive as possible. I bought these clear suction cups separately. I'm not using it but keeping it in case. Third- pull the divider all the way up. I turn a 10-gallon tank into three, 3. Overall I was pleased with this divider.

"The choice is yours!"

It's good for what I needed it for. Very few problems just a couple things to keep in mind when buying. Not worried about the small fish due to the size of the fry. Second- Do not recommend for bettas or small fish! Even though there are holes in the acrylic the water flow is not the same. I have to trim off about a quarter inch and then they work just fine. I did not receive suction cups but I had my own to it did what I was looking for.

"Excellent product!"

They can still see each other and try to fight through the barrier but its a no go. So if you have the exact tank, it would be perfect. There were scratches when we got this so I originally gave it one star review. I got this to keep my albino Koi guppies separated from my fancy males. Take it from us— follow the instructions about what type to use! You can also try any other small fish. It is easy to install but, careful not to lose anything.
