"Great purchase!"

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. Barrier is like a plastic mesh screen that allows water to flow through. It was slightly long so I had to trim off the bottom edge to make it fit. Doesn't obstruct the look of my fish tank. They look like the edging that's on the tanks, so it's as attractive as possible. Worth it though if you have money to blow.

Chnee Final Thoughts

"I tried and tried."

You just need to peel of the protective layer from both sides. This worked perfectly for my 55 gallon aquarium. Works wonders for our water turtle tank. You can customize the to whichever size you like and the suctions are great. Im using them to hold airline tubing. I know Betta fish are aggressive, so they must be separated. I used this to separate my two Betta fish in a 10 gallon tank.

"Worked like a charm."

I actually like how tight it fits so it won't get dislocated accidentally. Works great and we have it holding a divider in a lizard tank. I created an inexpensive portable indoor potty for my little dog. This is THE BEST divider I've found! Not worried about the small fish due to the size of the fry. It comes with MANY suction cups and attachments. I will be buying more of this I recommend them 100%.

"They are plastic grids."

Only reason I took a star off was the price. The holes are smaller than some other similar dividers, which is why I chose these. Third- pull the divider all the way up. I would much rather be able to see my whole tank the rest of the day. Will certainly be buying more of these! You will have to cut them to fit any other size aquarium. I came back to give it a 4 star review!

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.

spritool Final Thoughts

"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 highly recommend!"

It was a bit too wide for my tank, so I cut it a bit and it's perfect. It dose have good flow between the tanks. Holes are drilled evenly and it will divide fish 1. I'm separating male and female cichlids. There were scratches when we got this so I originally gave it one star review. I had an oddly aggressive Molly and this worked great for the time I needed to use. And if you fill your tank very full with water they can swim over the divider.

LANDUM Final Thoughts

"Very carefully machined."

It comes with MANY suction cups and attachments. This WILL fit an Aqueon tall 10 gallon, but NOT a Top Fin tall 10 gallon. I am going to put a Male betta on each side. You can also try any other small fish. Make sure to set it up in the middle of the water pump. A silicone tray, Charcoal potty pad, and this grid. Barrier is like a plastic mesh screen that allows water to flow through.

"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!

"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.

"And transparent."

It comes in clear so I had to rough up both sides to make it opaque. It is a bit tricky to straighten it and clip it, but with a bit of a push, it's fine. For platty fry I reccomend the Petzilla Aquarium Fish Breeder box. Small, skinny betta can go through those. I cut it to size using a paper cutter because it was easier than scissors. And I've been in the hobby a long time! I've bought several of these to divide my betta's and they've been great!

I have it in a divided ten gallon with two bettas.

"But it keeps adults in."

I got this so I could put two male bettas in a tank. It comes in clear so I had to rough up both sides to make it opaque. Im using them to hold airline tubing. So I divided it allowing me to have 2 tanks in one large tank. 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! This product is one that I would be really sad to see disappear.

"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.
