Aqua design amano. Very well know for quality and appeal. Very expensive which is why I'm cautious of putting a hole in it.. basically you will never find a tank with the quality of these, all rimless and you will not find a defect in the silicone. Some of the products are expensive because of the logo, the tanks though can't be beat. And its not a dumb question, you just didn't know. No big deal. Also, they have tanks with built in glass overflows but the small one at I think 30 or 40 gallons starts at 500$
