"Otherwise very good."

Will certainly be buying more of these! My only small issue with it is the way it attaches to the tank. My dog can use her indoor potty and keep clean and dry above the pad. I did not receive suction cups but I had my own to it did what I was looking for. Very good divider for my 20 gal long freshwater aquarium. If you have the divider in the gravel it will not meet the top of the tank. You do have to assemble it yourself but that isn't too hard.

"5 gallon fabric pots."

I will be buying more of this I recommend them 100%. Very tight fit with hardly any gap. Purchased this to temporarily divide a 20-long tank for axolotls. Very pleased with this tank divider. Get this if your dividing your tank for betta fish. This WILL fit an Aqueon tall 10 gallon, but NOT a Top Fin tall 10 gallon. I have it in a divided ten gallon with two bettas.

"I think these are great."

It is thick, well made and a great addition if you have the tank they specified. I would much rather be able to see my whole tank the rest of the day. It is easy to install but, careful not to lose anything. Perfect fit, easy to install, and ideal design. I'll keep it for separating parts of my tank as I plant new areas but not for fry. You can customize the to whichever size you like and the suctions are great. Not sure I would recommend it for fry however.

"Easy to put in tank."

Very pleased with this tank divider. Fish can't swim to the other side anymore, and it looks super cool. I got this to keep my albino Koi guppies separated from my fancy males. Easy to use and perfect for my tank! Don't think so, unless it’s not in water. I would much rather be able to see my whole tank the rest of the day. There are slots along the top that they can see through.

"Excellent product!"

Second- Do not recommend for bettas or small fish! It worked well in my very small 12 gallon show tank. Only because of that reviewer, I was able to use them the way I intended. If you have the divider in the gravel it will not meet the top of the tank. It was a bit too wide for my tank, so I cut it a bit and it's perfect. Only reason I took a star off was the price. Make sure you read the instructions and have the right type of aquarium!

"Cut to fit snug."

You can also try any other small fish. I found these and now have 6 of them for my male bettas. Fish can't swim to the other side anymore, and it looks super cool. I have it in a divided ten gallon with two bettas. They can still see each other and try to fight through the barrier but its a no go. Very few problems just a couple things to keep in mind when buying. I have to trim off about a quarter inch and then they work just fine.

"The choice is yours!"

We have four South American cichlids that do not live in harmony together. Im using them to hold airline tubing. So if you have the exact tank, it would be perfect. Divider works well for our two Bettas that share a 10 gallon aquarium. You will need fingernails to peel them. My betta fish even got in fights 3 times because the went through them. Look closely at the slight taper in the connections to see which way to insert them.

"However, I bought the 15."

So I divided it allowing me to have 2 tanks in one large tank. You will need fingernails to peel them. Giving it 4 stars due to the high price of something so simple. I created an inexpensive portable indoor potty for my little dog. The gravel along with the quick trim left no gaps for me. Will certainly be buying more of these! My dog can use her indoor potty and keep clean and dry above the pad.

"And they connected!"

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.

"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!

Generic Final Thoughts

"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.

"Good divider!"

This was clear, easy to install, and well made. Will certainly be buying more of these! Perfect fit, easy to install, and ideal design. You need to use a mallet to connect the panels together. This worked perfectly for my 55 gallon aquarium. That was another battle trying to get those on. This was clear, easy to install, and well made.

"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.
