"3-gallon tanks."

The holes are smaller than some other similar dividers, which is why I chose these. This product is one that I would be really sad to see disappear. The gravel along with the quick trim left no gaps for me. Overall this has done the job I've needed to. I will be buying more of this I recommend them 100%. Fish can't swim to the other side anymore, and it looks super cool. However, it was easy to install and it worked pretty well in the last few weeks.

"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.

JARDIN Jardin Final Thoughts

"The choice is yours!"

It's good for what I needed it for. Very few problems just a couple things to keep in mind when buying. Not worried about the small fish due to the size of the fry. Second- Do not recommend for bettas or small fish! Even though there are holes in the acrylic the water flow is not the same. I have to trim off about a quarter inch and then they work just fine. I did not receive suction cups but I had my own to it did what I was looking for.

"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.

"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.

"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.

"Kept fish apart."

I got this to keep my albino Koi guppies separated from my fancy males. The product comes with many small plastic pieces. It was a bit too wide for my tank, so I cut it a bit and it's perfect. Works great and we have it holding a divider in a lizard tank. I did have to bury the bottom in about an inch or so of gravel to keep it in place. I would much rather be able to see my whole tank the rest of the day. The product comes with many small plastic pieces.

"I love this!"

It assembled quickly and painlessly. And if you fill your tank very full with water they can swim over the divider. You will have to cut them to fit any other size aquarium. There are slots along the top that they can see through. I got this so I could put two male bettas in a tank. Description says if they dont go together use zip ties. Third- pull the divider all the way up.

I did not receive suction cups but I had my own to it did what I was looking for. Would recommend two smaller filters on either side to help water flow. Easy to use and perfect for my tank! Will certainly be buying more of these! Actually adds additional filtration I think. My betta fish even got in fights 3 times because the went through them.

"Great customer service."

Doing these two things really keeps this thing in place. It was slightly long so I had to trim off the bottom edge to make it fit. Worth it though if you have money to blow. 6-25-19- I had to make a minor adjustment to my divider. Very sturdy, has clips on the sides to keep in place. The connection joints are very snug.

"Becomes a bit cloudy."

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.

"The tank is only 7."

The female is on the larger side with her babies. This is THE BEST divider I've found! Description says if they dont go together use zip ties. There were scratches when we got this so I originally gave it one star review. Second- Do not recommend for bettas or small fish! I'm separating male and female cichlids. The gravel along with the quick trim left no gaps for me.

"Sticks on glass."

For platty fry I reccomend the Petzilla Aquarium Fish Breeder box. The divider itself works very well and seems sturdy. Actually adds additional filtration I think. You just need to peel of the protective layer from both sides. Very few problems just a couple things to keep in mind when buying. I uploaded a video to demonstrate the barrier in action xD. Worth it though if you have money to blow.

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.

"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.
