20 Gallon Aquarium Divider with Suction Cups - Fish Tank Divider Perfect for Betas

I purchased this divider for a 20 long aquarium because I had an order of cichlids coming from Live Fish Direct that needed to be placed in three different permanent tanks after quarantine. Having only a 10 and 20 long tank, the divider did the job of housing the cichlids in 3 separate areas until they were ready for their permanent homes.Assembly was quick and easy, the fit was great and well worth the cost of the product.Kudos to the company for foresight, as they included a few extra pins and cups, just in case.I would be leery of any negative reviews after using the product, assuming they either came from competitors or people that have problems when they buy a pack of light bulbs because they do not come already assembled in a lamp.

I put this in my tank. Seemed to fit perfectly. No gaps (I set it out for a couple days with a book on it before putting it in the tank because it comes rolled up).Within 30 min one of our fish had wedged itself between the glass and this divider. We really thought he was dead but luckily he was not. After a few mor times of this happening I removed it and threw it away. Waste of money if it literally doesn’t do the one job it’s made for.

Let me start by saying thank you to the company who made this that decided to put extra pins in for each divider. I broke 3 pins when trying to put my dividers together and thankfully they gave enough extra that i could still get it together. I havent tried these dividers with my fish yet as they havent arrived but they look like the have good flow and although were annoying to put together they appear to be very sturdy and fit perfectly in my 20 gallon Long tank.

Works well. Sticks to walls fine. Reviews complained that theres was rolled up and wouldnt flatten. Mine was rolled up, i rolled in the opposite way and let it sit for a few minutes. After that it was fine to be set up in tank. Only issue i had were that the small sticks that lock the screen into the end pieces, were so fragile and broke on me without going fully though the screen, but also got stuck so i couldnt fix it with another stick. So a few spots on my screen are not fastened completely due to sticks breaking and getting stuck. But it is separating my two betas just fine. They dont antagonize eachother through the screen at all. I'm sure they know the other is on the other side but they don't seem to see eachother

I had to buy 10 gallon divider for a 5 gallon tank for 2 bettas. I used scissors for the rubber divider to cut to size. Had to use a hand saw to cut the support plastics to size. It would be 5 stars if getting the pins in were a bit easier. I used a drill to expand the opening slightly and it worked great. The suction is great. It does move! Which makes it had to put in place at first. I installed in an empty tank. I would recommend even if you need to cut it. Other divider on the market just plain are horrible.

We used this divider to create a split tank to introduce new gerbils to our other gerbil after her sister passed. It fit our tank very well, it was maybe a half an inch too big but we just slanted it in the tank. We just needed something to keep them apart but still give them the chance to get used to each other and this was a great solution. They did nibble at the plastic a little but there were no issues. After a week we were able to take the divider out and they are living as a clan now. The suction cups were very strong. This is made of thick sturdy plastic.

I'm gonna say, it fits perfectly in my 20 gallon long tank, nice and snug. Maybe just a tiny bit too snuck but at a slight angle it works. I had it under a huge stack of heavy books for days and it did nothing to flatten it out. It comes rolled up in a thin box and is almost permanently curled for the most part. When you straighten it by putting on the edges you get some warping. Mine also came with a few cracked holes shown in the second picture, as if trying to straighten the semi-flexible rubber/plastic stuff broke it. Also the screws are plastic, they break SUPER easy. But they give you plenty. Overall, I'd say I'd buy this for maybe 9.99 but definitely not for 20 dollars!

Bought this to separate my baby Axolotl from my juvenile Axolotl. It fits perecftly in my size 20l tank. I wish the holes in the screen were just a little bit bigger so more participles could pass through it but overall does a good job. Note that it does come rolled very tightly- to get it flat I ironed it with a piece of fabric over it to not burn it. Once it was hot from being ironed I just rolled it the other direction and it flattened out.
