I know 'they' make a special glass for fish tanks. What's it called
and where can I buy it? 20g. Already built.

Ordinary glass works fine. You can even used tempered glass, but you
have to be really careful working with it because it shatters if you
drill into it.

Glass is much harder than acrylic (although it can still scratch). But it
tends to be much heavier, and not quite as clear. Often has some optical
distortion, and often a greenish tint.

There's a special aquarium glass, called "Starfire" glass, which is designed
just for aquariums and has better optical properties. More expensive though.

Acrylic sucks. 1 grain of sand caught in the magnetic algae scrapper
**** my tank up like you wouldn't believe. End of plastic for me.

Yeah, I've got an acrylic tank too (after starting with glass), and I don't
care for it either.

Much easier to scratch, much harder to scrape off the coraline algae, and
it requires cross bracing at the top to hold the weight of the water. I
don't like any of that.
