"Love this seat cover."

They can see each other but they can't fight. Would recommend two smaller filters on either side to help water flow. Im using them to hold airline tubing. This product is one that I would be really sad to see disappear. It is a bit tricky to straighten it and clip it, but with a bit of a push, it's fine. I actually like how tight it fits so it won't get dislocated accidentally. Giving it 4 stars due to the high price of something so simple.

"Love this seat cover."

The only con is that it's see through. Giving it 4 stars due to the high price of something so simple. Purchased this to temporarily divide a 20-long tank for axolotls. 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. Doing these two things really keeps this thing in place. It worked well in my very small 12 gallon show tank.

"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.

"Perfect egg tray."

It worked well in my very small 12 gallon show tank. It is a thick sturdy plastic, and the suction power is strong. Don't think so, unless it’s not in water.

"Easy to put in tank."

I created an inexpensive portable indoor potty for my little dog. They can see each other but they can't fight. This product is one that I would be really sad to see disappear. I used this to separate my two Betta fish in a 10 gallon tank. Very pleased with this tank divider. This are black in they stick to the tank not like glue or anything lol. Overall I was pleased with this divider.

"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.

"I love this."

It was slightly long so I had to trim off the bottom edge to make it fit. It is thick, well made and a great addition if you have the tank they specified. It was a bit too wide for my tank, so I cut it a bit and it's perfect. It comes with MANY suction cups and attachments. So I divided it allowing me to have 2 tanks in one large tank. It was a bit too wide for my tank, so I cut it a bit and it's perfect. I found these and now have 6 of them for my male bettas.

"Works great."

My dog can use her indoor potty and keep clean and dry above the pad. I will be buying more of this I recommend them 100%. The only con is that it's see through. It was a bit too wide for my tank, so I cut it a bit and it's perfect. However, it was easy to install and it worked pretty well in the last few weeks. Didn't ruin the look of the tank nor interfere with tank filter system. 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.

"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.

"Excellent product!"

The gravel along with the quick trim left no gaps for me. This is a great option for keeping two bettas in the same tank! I used this to separate my two Betta fish in a 10 gallon tank. They can still see each other and try to fight through the barrier but its a no go. It is a thick sturdy plastic, and the suction power is strong. It dose have good flow between the tanks. No it doesnt come with the suction cups.

"Otherwise very good."

Will certainly be buying more of these! My only small issue with it is the way it attaches to the tank. My dog can use her indoor potty and keep clean and dry above the pad. I did not receive suction cups but I had my own to it did what I was looking for. Very good divider for my 20 gal long freshwater aquarium. If you have the divider in the gravel it will not meet the top of the tank. You do have to assemble it yourself but that isn't too hard.

I will be buying more of this I recommend them 100%. Very tight fit with hardly any gap. Purchased this to temporarily divide a 20-long tank for axolotls. Very pleased with this tank divider. Get this if your dividing your tank for betta fish. This WILL fit an Aqueon tall 10 gallon, but NOT a Top Fin tall 10 gallon. I have it in a divided ten gallon with two bettas.

Even though there are holes in the acrylic the water flow is not the same. It is a bit tricky to straighten it and clip it, but with a bit of a push, it's fine. So I'm writing this to tell you you step on them. Look closely at the slight taper in the connections to see which way to insert them. I also found out small fish can easily swim between the gaps on the sides. They can see each other but they can't fight. I found these and now have 6 of them for my male bettas.

"Works as intended!"

6-25-19- I had to make a minor adjustment to my divider. I cam keep my 2 betta fish in the same tank now. We have four South American cichlids that do not live in harmony together. I personally only want to put the separator in for just feeding time. Holes are big enough for good circulation throughout the tank. It was slightly long so I had to trim off the bottom edge to make it fit. They look like the edging that's on the tanks, so it's as attractive as possible.
