"Works pretty well."

My betta fish even got in fights 3 times because the went through them. The fry didn't understand so they swam through the sides. This worked perfectly for my 55 gallon aquarium. I actually like how tight it fits so it won't get dislocated accidentally. It comes with MANY suction cups and attachments. I'm separating male and female cichlids. If you have the divider in the gravel it will not meet the top of the tank.

"They don't snap together."

Let's water flow freely through our entire tank. I created an inexpensive portable indoor potty for my little dog. I would much rather be able to see my whole tank the rest of the day. Product works great if you can figure out how to fit it into your fish tank. Holes are drilled evenly and it will divide fish 1. Holes are big enough for good circulation throughout the tank. I uploaded a video to demonstrate the barrier in action xD.

"Works well."

The gravel along with the quick trim left no gaps for me. It worked well in my very small 12 gallon show tank. I got this to keep my albino Koi guppies separated from my fancy males. My only small issue with it is the way it attaches to the tank. I mean, it's an aquarium divider lol. Holes are big enough for good circulation throughout the tank. Look closely at the slight taper in the connections to see which way to insert them.

"Had to go another way."

Make sure to set it up in the middle of the water pump. They can see each other but they can't fight. My male bettas could see each other along the top of the divider. My only small issue with it is the way it attaches to the tank. I have it in a divided ten gallon with two bettas. I have it in a divided ten gallon with two bettas. And if you fill your tank very full with water they can swim over the divider.

3. Balacoo 2Pcs Aquarium Grid Divider Fish Tank Mixed Breeding Isolation Bord Black Filter Net

Balacoo First Impressions

"Works perfectly."

Description says if they dont go together use zip ties. I cut it to size using a paper cutter because it was easier than scissors. So if you have the exact tank, it would be perfect. Barrier is like a plastic mesh screen that allows water to flow through. Even though there are holes in the acrylic the water flow is not the same. They look like the edging that's on the tanks, so it's as attractive as possible. Very sturdy, has clips on the sides to keep in place.

Balacoo Final Thoughts

"Also looks well."

I came back to give it a 4 star review! The first time we tried using this, we cracked an empty one. We have four South American cichlids that do not live in harmony together. Worth it though if you have money to blow. Not sure I would recommend it for fry however. You do have to assemble it yourself but that isn't too hard. It is easy to install but, careful not to lose anything.

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. Make sure you read the instructions and have the right type of aquarium! The only con is that it's see through. I bought these clear suction cups separately. Got it for my bettas fish,male and female.

Balacoo 1939ZQPO6182MH6 Final Thoughts

"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.

BILLIOTEAM Final Thoughts

"So dont assume they do."

It's great products, fit perfectly and fast shipping. It comes in clear so I had to rough up both sides to make it opaque. This WILL fit an Aqueon tall 10 gallon, but NOT a Top Fin tall 10 gallon. It is difficult to move the side bars to move out to close the gaps. I know Betta fish are aggressive, so they must be separated. You will have to cut them to fit any other size aquarium. The only con is that it's see through.

"It's fairly easy to do."

Small, skinny betta can go through those. No it doesnt come with the suction cups. I uploaded a video to demonstrate the barrier in action xD. The first time we tried using this, we cracked an empty one. You need to use a mallet to connect the panels together. I had an oddly aggressive Molly and this worked great for the time I needed to use. You just need to peel of the protective layer from both sides.

I actually like how tight it fits so it won't get dislocated accidentally. Two were forced to spend most of their time in hiding. This WILL fit an Aqueon tall 10 gallon, but NOT a Top Fin tall 10 gallon. It is thick, well made and a great addition if you have the tank they specified. This is THE BEST divider I've found! Works wonders for our water turtle tank. My dog can use her indoor potty and keep clean and dry above the pad.

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.
