"They worked like a charm."

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. Not worried about the small fish due to the size of the fry.

"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. It was slightly long so I had to trim off the bottom edge to make it fit.

"Excellent product!"

Second- Do not recommend for bettas or small fish! It worked well in my very small 12 gallon show tank. Only because of that reviewer, I was able to use them the way I intended. If you have the divider in the gravel it will not meet the top of the tank. It was a bit too wide for my tank, so I cut it a bit and it's perfect. Only reason I took a star off was the price. Make sure you read the instructions and have the right type of aquarium!

"Cut to fit snug."

You can also try any other small fish. I found these and now have 6 of them for my male bettas. Fish can't swim to the other side anymore, and it looks super cool. I have it in a divided ten gallon with two bettas. They can still see each other and try to fight through the barrier but its a no go. Very few problems just a couple things to keep in mind when buying. I have to trim off about a quarter inch and then they work just fine.

"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.

"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.

"They don't snap together."

And now I know they are getting enough to eat. We have four South American cichlids that do not live in harmony together. It keeps the boys from being able to see each other. 4stars because it says easy to connect peices together. It worked well in my very small 12 gallon show tank.

"Excellent product!"

I turn a 10-gallon tank into three, 3. They can see each other but they can't fight. I also found out small fish can easily swim between the gaps on the sides. I did have to bury the bottom in about an inch or so of gravel to keep it in place. You need to use a mallet to connect the panels together. You just need to peel of the protective layer from both sides. Two were forced to spend most of their time in hiding.

"They were all awful!"

You will need fingernails to peel them. I used this product to divide my 10gallon tank. Easy to use and perfect for my tank! You can also cut it down to the size of your tank, which was not too difficult to do. I cam keep my 2 betta fish in the same tank now. This product is one that I would be really sad to see disappear. If you have the divider in the gravel it will not meet the top of the tank.

"Worked perfectly."

You need to use a mallet to connect the panels together. I personally only want to put the separator in for just feeding time. I actually like how tight it fits so it won't get dislocated accidentally. It is thick, well made and a great addition if you have the tank they specified. You need to use a mallet to connect the panels together. For platty fry I reccomend the Petzilla Aquarium Fish Breeder box. This WILL fit an Aqueon tall 10 gallon, but NOT a Top Fin tall 10 gallon.

"Works as intended!"

The only con is that it's see through. The first time we tried using this, we cracked an empty one. And if you fill your tank very full with water they can swim over the divider. This was clear, easy to install, and well made. However, keep in mind this tank divider does not fit just ANY 10 gallon! They can see each other but they can't fight. Small, skinny betta can go through those.

"5 gallon fabric pots."

A silicone tray, Charcoal potty pad, and this grid. Giving it 4 stars due to the high price of something so simple. My dog can use her indoor potty and keep clean and dry above the pad. I'll keep it for separating parts of my tank as I plant new areas but not for fry. Im using them to hold airline tubing. Not worried about the small fish due to the size of the fry. Doing these two things really keeps this thing in place.

Get this if your dividing your tank for betta fish. Overall I was pleased with this divider. Make sure you read the instructions and have the right type of aquarium! If you have the divider in the gravel it will not meet the top of the tank. Holes are big enough for good circulation throughout the tank.
