"Great water flow."

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.

"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.

Ujuuu First Impressions

"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. I had an oddly aggressive Molly and this worked great for the time I needed to use. No matter what size betta I put I know it won't go through the divider.

"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.

"Had to go another way."

Take it from us— follow the instructions about what type to use! Easy to use and perfect for my tank! Would recommend two smaller filters on either side to help water flow. I would much rather be able to see my whole tank the rest of the day. I created an inexpensive portable indoor potty for my little dog. I have it in a divided ten gallon with two bettas. It's good for what I needed it for.

"The choice is yours!"

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. Actually adds additional filtration I think. It is thick, well made and a great addition if you have the tank they specified. There are slots along the top that they can see through. It worked well in my very small 12 gallon show tank. I bought these clear suction cups separately.

RA AquaTech First Impressions

"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.

"Works well."

My only small issue with it is the way it attaches to the tank. Small, skinny betta can go through those. They can still see each other and try to fight through the barrier but its a no go. This WILL fit an Aqueon tall 10 gallon, but NOT a Top Fin tall 10 gallon. Make sure it is tight and smooth on the sides of the tank. Im using them to hold airline tubing. I have it in a divided ten gallon with two bettas.

Very pleased with this tank divider. Overall this has done the job I've needed to. Second- Do not recommend for bettas or small fish! I mean, it's an aquarium divider lol. I've bought several of these to divide my betta's and they've been great! I cut it to size using a paper cutter because it was easier than scissors. It's good for what I needed it for.

"Sold separately."

That was another battle trying to get those on. Works great and we have it holding a divider in a lizard tank. Barrier is like a plastic mesh screen that allows water to flow through. That was another battle trying to get those on. Two were forced to spend most of their time in hiding. I turn a 10-gallon tank into three, 3. You will need fingernails to peel them.

"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.

"However, I bought the 15."

So I divided it allowing me to have 2 tanks in one large tank. You will need fingernails to peel them. Giving it 4 stars due to the high price of something so simple. I created an inexpensive portable indoor potty for my little dog. The gravel along with the quick trim left no gaps for me. Will certainly be buying more of these! My dog can use her indoor potty and keep clean and dry above the pad.

"What I expected."

The flow holes allowed for ample current and water circulation. First- When dividing a 10 gallon tank the flow is not the same. It dose have good flow between the tanks. This product is one that I would be really sad to see disappear. I did have to bury the bottom in about an inch or so of gravel to keep it in place. This fit PERFECTLY in our 75 gallon aquarium. The fry didn't understand so they swam through the sides.

Very good divider for my 20 gal long freshwater aquarium. It was a bit too wide for my tank, so I cut it a bit and it's perfect. Not sure I would recommend it for fry however.
