"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.

OIIKI Final Thoughts
"5 gallon fabric pots."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.

"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.

3. uxcell Pairs Aquarium Tank Glass Cover Clip Support Holder 4-12mm
uxcell US-SA-AJD-22515 First Impressions
"Worked like a charm."First- When dividing a 10 gallon tank the flow is not the same. Take it from us— follow the instructions about what type to use! The fry didn't understand so they swam through the sides. You will have to cut them to fit any other size aquarium. Let's water flow freely through our entire tank. It was slightly long so I had to trim off the bottom edge to make it fit. I had ordered 3 others before this one.

"Definitely not easy."And since it has been working ok, I decided to change the review to 4 star. Two were forced to spend most of their time in hiding. I had an oddly aggressive Molly and this worked great for the time I needed to use. This is a great option for keeping two bettas in the same tank! 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. Barrier is like a plastic mesh screen that allows water to flow through.

"Otherwise very good."You can customize the to whichever size you like and the suctions are great. I have to trim off about a quarter inch and then they work just fine. Nice, thick and attractive divider. They can still see each other and try to fight through the barrier but its a no go. Barrier is like a plastic mesh screen that allows water to flow through. So I divided it allowing me to have 2 tanks in one large tank. I mean, it's an aquarium divider lol.

"However, I bought the 15."It's great products, fit perfectly and fast shipping. Very tight fit with hardly any gap. My dog can use her indoor potty and keep clean and dry above the pad. It assembled quickly and painlessly. This fit PERFECTLY in our 75 gallon aquarium. Look closely at the slight taper in the connections to see which way to insert them. Small, skinny betta can go through those.

J-star First Impressions
"It's fairly easy to do."It dose have good flow between the tanks. And if you fill your tank very full with water they can swim over the divider. I would much rather be able to see my whole tank the rest of the day. The connection joints are very snug. Two were forced to spend most of their time in hiding. I bought these clear suction cups separately. It keeps the boys from being able to see each other.

"However, I bought the 15."Only because of that reviewer, I was able to use them the way I intended. I'll keep it for separating parts of my tank as I plant new areas but not for fry. Actually adds additional filtration I think. I actually like how tight it fits so it won't get dislocated accidentally. You need to use a mallet to connect the panels together. I got this so I could put two male bettas in a tank. We have four South American cichlids that do not live in harmony together.

"Otherwise very good."And I've been in the hobby a long time! I can see why people thought it was white. The female is on the larger side with her babies. It was a bit too wide for my tank, so I cut it a bit and it's perfect. And since it has been working ok, I decided to change the review to 4 star. Don't think so, unless it’s not in water. It comes with MANY suction cups and attachments.

"Made a shelf in my sump."I'm not using it but keeping it in case. Two were forced to spend most of their time in hiding. You do have to assemble it yourself but that isn't too hard. And I've been in the hobby a long time! I did have to bury the bottom in about an inch or so of gravel to keep it in place. You can also try any other small fish. Description says if they dont go together use zip ties.

"Love this seat cover."The first time we tried using this, we cracked an empty one. 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. Very tight fit with hardly any gap. Works great and we have it holding a divider in a lizard tank. Make sure to set it up in the middle of the water pump. Would recommend two smaller filters on either side to help water flow.

"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.

"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.
