It's a Perfecto brand lid. Measurements are 3/16" too wide. But with the addition on some silicone edging, it fits on top of the tank (instead of in the rim) and the edging reduces vibration/ noise. If the Measurements were correct or the edging was supplied, I would have given it 5 stars.
Still a good lid but options are extremely limited for these sized tanks - so it's hard to make any comparison.
A great healthy snack for my babies and getting them delivered was awesome as well!
My puppy has an extremely sensitive stomach and can't have traditional long lasting treats and chews but didn't lkke kongs. I fill the large toppl with her kibble, soak and freeze it and it lasts her at least a full hour, sometimes longer.
It's durable, and so so easy to clean. I have two now.
The best way I have found to do plant moves within the aquarium. It is quick and easy.
