20 Gallon Long Aquarium Tank Divider (3 Pack) Check Compatible Tank Below.

Black color dividers were impossible to find until these, works great

I have used these in my 20L aquarium now for months, they do the job as long as you make sure they are pretty snuggly attached to the tank walls.

I love these dividers, they are perfect for bettas. They are EXTREMELY easy to set up. These dividers also look so nice in any split tank. 10/10 recommend for anyone making a split tank, the price is 100% worth it.

these dividers worked great in the proper aquarium ..I tried the 10 gallon in an aquarium I got at Walmart and they did NOT fit but this was my mistake...when I used the 20 log dividers in a Aqueion brand aquarium all was perfect and very easy to use...just don't try with a different brand than specified...

The panels are all loose fitting and have cracks on each side that my Berta can see through. All betta fish are different so others may not have this problem if your betta is docile but one of mine is quite aggressive and kept going to the sides where they could see each other and just barely not escape into the others tank. I have aqueon 20 long which is what they said is needed. I will have to buy better ones as the stress is getting to both my betta and me. I had to improvise and fill in the sides it not sturdy and definitely not Worth the priceUpdate: one of my males was able to slip though the opening of the barrier against the tank and get to the other side and was fighting with my other male betta when I found him. Definitely do Not but. Terrible product

Picked these up for my 20 long betta tank. They are sturdy but the tabs that help hold them in place shift a little. An easy fix there I used a little hot glue on the frame to keep them in place. 2 out of the 3 dividers was flush against the walls with no place to slide but the third had some space and one of my bettas slid past. (Luckily i hadn't put my other betta in so no fights. ) To fix this I used plastic mesh to fill the gap in. Over all they are good dividers not bad for the price. But you have to be a little creative to make them work 100%.

Couldn’t be any happier.If you received this as foam then you got scammed, this product is made of pvc it’s sturdy plastic. And it’s only made for aqueon fish tanks. Any other brand it will give you complications.I bought 5 packs of 3 and they all fit perfectly in my 20g long Aqueon tanks.

Very expensive dividers that fish can squeeze through honestly I’m really disappointed my betta and guppies squeeze through to the other side.
