With the Penn-Plax Tank Divider, you can instantly transform one aquarium into two. Quick and simple to install, this polymer screen is helpful for creating an area for breeding and baby fish or for separating rough fish. The screen is perforated to allow water to circulate and filter freely and to ensure that the entire tank has the proper heat flow. The Penn-Plax Tank Divider can be trimmed so you can guarantee the perfect fit. It’s an easy and convenient way to keep your fish protected without major tank modifications.
Ideal for smaller aquariums up to 10-gallons
Converts one aquarium into two separate for breeding and baby fish or for more aggressive/rough fish
Allows unrestricted filtration and heater circulation throughout the aquarium
Works well in my 10 gal. Kind of flimsy and doesn’t fit snug at all. One bump and it’ll knock a gap between the glass and the blue rimming. Just needs secured with large rocks one on each side of each corner to ensure no gaps.

Works perfectly and leaves almost no space between the divider and tank
Keeps bettas away from each other and seems really sturdy

It's doing a great job keep my 2 betta fish separated.
Wonderful for my twenty gallon long!

This is a very sturdy divider, and easy to trim to fit if need be. My otocinclus WAS able to wiggle through the sides, but he’s also not even half an inch wide. I’m very satisfied with this divider. I was able to fit both my betas in it and get rid of two aquariums.
Babies have one-third of tank to swim in

I ordered this because my guppy had probably 40 young and needed to block off one-third of the tank. It works very well and everyone is happy. Easy to put together yet sturdy.
I love this Divider

Fits perfectly in my 10 Gallon fish tank. So far so good, it holds firmly into position. This divider makes the cleaning so easy where I don't have to remove it, just what I was looking for.
Not the best idea

Keeps fish separated but it doesn’t allow for filtration to work well enough to keep the water clean...
Wish it was remodeled

I need a tank divider. I have 6 tanks could use a few. I think this divider would work in a 10 gallon tank or 20 L but nothing larger than that.
Don't understand the bad reviews

I love this thing. Too me two seconds to install. I just bought two more for my bettas.
Not sure why teal
on Aug 13, 2019
Works well but the teal holding strips really stick out like a sore thumb. Wish they had made those clear making them less noticeable. Aquariums are glass/plexiglass... why teal?
