Answer by ChewyMay 03, 2021
This cover measures 30 inches long by 12 inches wide. It is designed to fit most 20-29 gallon aquariums and glass tanks..

is this good for a sliding lid my tank requires a sliding lid
Answer by ChewyJan 28, 2020
This screen cover sits on top of the tank and is not a sliding lid.

Will this screen work on a glass tank that doesn’t have a top rim?

This cover is suitable for both aquariums and glass tanks.

is this cover made from screen mesh or metal screen
Answer by ChewyOct 05, 2021
The screen is made of strong metal and is designed to provide ventilation and allow necessary UV penetration while ensuring reptiles, feeder insects, and other small animals are safely secured.

Really good

It came nicely packaged no scratches or damages at all and it perfectly fits into my 20 gallon tank with a bit a wiggle room. 10/10 I highly recommend!

Breathable lid for 20gal long

Very pleased with this cover. My cat can sit on it and not fall in. And it's heavy enough nothing's going to escape. I have one over my axolotl tank. I have rubber tubing coming out of the tank and this sits nicely on top without crushing the tubes, yet still keeps the cat out. I have another one on my 29 gallon tank for my gecko. I have fan blowing through the screen for my axolotl. And I have a heat lamp sitting directly on it for my gecko. Very pleased with this cover.

Keeps Nake the Snake inside the Tank

I have a deep aquarium. It's 40+ gallons--- so bigger than screen cover is supposed to fit in item description. However, I measured the opening of my aquarium before buying and thought that it should work. And it did. Exactly as described.

Protect from cats

We had the standard slide-on lid that came with the tank. 10 minutes alone, and one of the cats sat on it to watch the gecko - of course fell in. We bought this one because it is heavy duty - works perfectly as intended - to sit ON TOP of the cage. It does NOT close tight, and needs the clips to keep more mobile terrarium pets inside, but is perfect to keep the cats out :) Can be used in addition to the slide on lid if you have escape concerns.

20 gallon long

It’s a little big but it fits. It doesn’t bother me because I’m using clamps to keep it in place.

good quality for price

Chewy is the cheapest place I could find this and so far it has held up to my cats laying on it all the tine. Can’t beat Chewy’s prices!
