"The tank is only 7."

The female is on the larger side with her babies. This is THE BEST divider I've found! Description says if they dont go together use zip ties. There were scratches when we got this so I originally gave it one star review. Second- Do not recommend for bettas or small fish! I'm separating male and female cichlids. The gravel along with the quick trim left no gaps for me.

WSERE Final Thoughts

"Sticks on glass."

For platty fry I reccomend the Petzilla Aquarium Fish Breeder box. The divider itself works very well and seems sturdy. Actually adds additional filtration I think. You just need to peel of the protective layer from both sides. Very few problems just a couple things to keep in mind when buying. I uploaded a video to demonstrate the barrier in action xD. Worth it though if you have money to blow.

"Also looks well."

This worked perfectly for my 55 gallon aquarium. No matter what size betta I put I know it won't go through the divider. Doing these two things really keeps this thing in place. Holes are big enough for good circulation throughout the tank. It is difficult to move the side bars to move out to close the gaps. I used this to separate my two Betta fish in a 10 gallon tank. 6-25-19- I had to make a minor adjustment to my 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.

"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.

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.

"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.

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.

"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!

"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.

Very few problems just a couple things to keep in mind when buying. It assembled quickly and painlessly. This is a great option for keeping two bettas in the same tank!

"They really stick too."

I created an inexpensive portable indoor potty for my little dog. You just need to peel of the protective layer from both sides. They can see each other but they can't fight. You do have to assemble it yourself but that isn't too hard. 6-25-19- I had to make a minor adjustment to my divider. Works wonders for our water turtle tank. Fish can't swim to the other side anymore, and it looks super cool.

"Perfect egg tray."

First- When dividing a 10 gallon tank the flow is not the same. I mean, it's an aquarium divider lol. I also found out small fish can easily swim between the gaps on the sides. The gravel along with the quick trim left no gaps for me. My betta fish even got in fights 3 times because the went through them. 6-25-19- I had to make a minor adjustment to my divider. Let's water flow freely through our entire tank.

"Go together easy."

It comes in clear so I had to rough up both sides to make it opaque. Very pleased with this tank divider. Giving it 4 stars due to the high price of something so simple. Purchased this to temporarily divide a 20-long tank for axolotls. There are slots along the top that they can see through. Doesn't obstruct the look of my fish tank. The only con is that it's see through.
