"They don't snap together."

And now I know they are getting enough to eat. We have four South American cichlids that do not live in harmony together. It keeps the boys from being able to see each other. 4stars because it says easy to connect peices together. It worked well in my very small 12 gallon show tank. Very good divider for my 20 gal long freshwater aquarium. Barrier is like a plastic mesh screen that allows water to flow through.

Yohii Final Thoughts

"Excellent product!"

I turn a 10-gallon tank into three, 3. They can see each other but they can't fight. I also found out small fish can easily swim between the gaps on the sides. I did have to bury the bottom in about an inch or so of gravel to keep it in place. You need to use a mallet to connect the panels together. You just need to peel of the protective layer from both sides. Two were forced to spend most of their time in hiding.

"The divider works well."

Overall this has done the job I've needed to. I also found out small fish can easily swim between the gaps on the sides. Divider works well for our two Bettas that share a 10 gallon aquarium. And I've been in the hobby a long time! We have four South American cichlids that do not live in harmony together. I created an inexpensive portable indoor potty for my little dog.

"I like Product."

It keeps the boys from being able to see each other. Only because of that reviewer, I was able to use them the way I intended. I have it in a divided ten gallon with two bettas. You need to use a mallet to connect the panels together. It is easy to install but, careful not to lose anything. The only con is that it's see through. This WILL fit an Aqueon tall 10 gallon, but NOT a Top Fin tall 10 gallon.

RMISODO Final Thoughts

"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.

JZMYXA First Impressions

"So I tried and tried."

Look closely at the slight taper in the connections to see which way to insert them. The fry didn't understand so they swam through the sides. I had ordered 3 others before this one. Very good divider for my 20 gal long freshwater aquarium. You can also cut it down to the size of your tank, which was not too difficult to do. I know Betta fish are aggressive, so they must be separated. And now I know they are getting enough to eat.

JZMYXA Final Thoughts

"Worked like a charm."

I uploaded a video to demonstrate the barrier in action xD. Fish can't swim to the other side anymore, and it looks super cool. Doing these two things really keeps this thing in place. Would recommend two smaller filters on either side to help water flow. The holes are smaller than some other similar dividers, which is why I chose these. You can also try any other small fish. Small, skinny betta can go through those.

"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.

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.

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.

"Love this seat cover."

They look like the edging that's on the tanks, so it's as attractive as possible. And now I know they are getting enough to eat. It was slightly long so I had to trim off the bottom edge to make it fit. No matter what size betta I put I know it won't go through the divider. And since it has been working ok, I decided to change the review to 4 star. It keeps the boys from being able to see each other. Divider works well for our two Bettas that share a 10 gallon aquarium.

WeiMeet Final Thoughts

"Hopefully."

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! I know Betta fish are aggressive, so they must be separated. Would recommend two smaller filters on either side to help water flow. Actually adds additional filtration I think. The female is on the larger side with her babies. This are black in they stick to the tank not like glue or anything lol.

"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.

"Let's face it."

Holes are drilled evenly and it will divide fish 1. My only small issue with it is the way it attaches to the tank. There are slots along the top that they can see through. I will be buying more of this I recommend them 100%. There were scratches when we got this so I originally gave it one star review. You need to use a mallet to connect the panels together. Overall I was pleased with this divider.

For platty fry I reccomend the Petzilla Aquarium Fish Breeder box. Only because of that reviewer, I was able to use them the way I intended. I'm separating male and female cichlids. You just need to peel of the protective layer from both sides. That was another battle trying to get those on. This are black in they stick to the tank not like glue or anything lol.
