I have a standard 10 gallon tank from Petco. This didn’t fit as the top was a cm too large. I like that the Perspex / acrylic is so clear. The holes also. My Bettas get along but I like to separate them every now and then - if I’m out of the house for more than 6 hours. I’ll try and find a 20 gallon that this could work for as it’s such great quality. Most Bettas need a black wall so they can’t see each other. If you buy this tall plants can help. Or one way film.

I bought this for my 3gallon tank to fit sideways / diagonally. I have a male & female betta fish. My female is quite small and will probably get through the side where the suction holds. Because this is designed to fit depth / width ways I returned it. But may buy again when I get a larger tank on December.I probably should have kept it as it was very clear and sturdy. I’d have not batted an eyelid if it was double the price.Arrived with a protective backing. I’ll shop for a ten gallon tank with this specific separator in mind.

On both sides, there was over an inch gap from top to bottom. Your fish will swim right through. Don't recommend at all

This is a great product, good quality, not flimsy like others I've purchased. I like the see thru clear color as others were black. Fit perfectly in my 10 gallon tank. Set up was a breeze.

Fit and worked out great
