"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.

J-star First Impressions

"It's fairly easy to do."

It dose have good flow between the tanks. And if you fill your tank very full with water they can swim over the divider. I would much rather be able to see my whole tank the rest of the day. The connection joints are very snug. Two were forced to spend most of their time in hiding. I bought these clear suction cups separately. It keeps the boys from being able to see each other.

"However, I bought the 15."

Only because of that reviewer, I was able to use them the way I intended. I'll keep it for separating parts of my tank as I plant new areas but not for fry. Actually adds additional filtration I think. I actually like how tight it fits so it won't get dislocated accidentally. You need to use a mallet to connect the panels together. I got this so I could put two male bettas in a tank. We have four South American cichlids that do not live in harmony together.

I got this so I could put two male bettas in a tank. I did have to bury the bottom in about an inch or so of gravel to keep it in place. I uploaded a video to demonstrate the barrier in action xD.

"Suctions not included."

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.

"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.

"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.

"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.
