"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.

"The choice is yours!"

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.

"Had to go another way."

Take it from us— follow the instructions about what type to use! Easy to use and perfect for my tank! Would recommend two smaller filters on either side to help water flow. I would much rather be able to see my whole tank the rest of the day. I created an inexpensive portable indoor potty for my little dog. I have it in a divided ten gallon with two bettas. It's good for what I needed it for.

"The choice is yours!"

The first time we tried using this, we cracked an empty one. It was a bit too wide for my tank, so I cut it a bit and it's perfect. Actually adds additional filtration I think. It is thick, well made and a great addition if you have the tank they specified. There are slots along the top that they can see through. It worked well in my very small 12 gallon show tank. I bought these clear suction cups separately.

"Sticks on glass."

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.

"Perfect height."

My dog can use her indoor potty and keep clean and dry above the pad. Not sure I would recommend it for fry however. I used this product to divide my 10gallon tank. It comes in clear so I had to rough up both sides to make it opaque. Would recommend two smaller filters on either side to help water flow. Description says if they dont go together use zip ties. Perfect fit, easy to install, and ideal design.

"And worth every penny!"

I'm not using it but keeping it in case. Look closely at the slight taper in the connections to see which way to insert them. It is thick, well made and a great addition if you have the tank they specified. Only because of that reviewer, I was able to use them the way I intended. This product is one that I would be really sad to see disappear. So I'm writing this to tell you you step on them. You will need fingernails to peel them.

RA AquaTech Final Thoughts

"Works well."

My only small issue with it is the way it attaches to the tank. Small, skinny betta can go through those. They can still see each other and try to fight through the barrier but its a no go. This WILL fit an Aqueon tall 10 gallon, but NOT a Top Fin tall 10 gallon. Make sure it is tight and smooth on the sides of the tank. Im using them to hold airline tubing. I have it in a divided ten gallon with two bettas.

"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.

"Works pretty well."

The holes are smaller than some other similar dividers, which is why I chose these. This is a great option for keeping two bettas in the same tank! Perfect fit, easy to install, and ideal design. I'm not using it but keeping it in case. I did have to bury the bottom in about an inch or so of gravel to keep it in place. It is thick, well made and a great addition if you have the tank they specified. The gravel along with the quick trim left no gaps for me.

"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.

Didn't ruin the look of the tank nor interfere with tank filter system. This worked perfectly for my 55 gallon aquarium.

Very sturdy, has clips on the sides to keep in place. Doing these two things really keeps this thing in place.

It's great products, fit perfectly and fast shipping. It is difficult to move the side bars to move out to close the gaps. It is thick, well made and a great addition if you have the tank they specified. I had an oddly aggressive Molly and this worked great for the time I needed to use. Very good divider for my 20 gal long freshwater aquarium. It was a bit too wide for my tank, so I cut it a bit and it's perfect. Not sure I would recommend it for fry however.
