author
Best known for a practical mid-century aquarium guide, this writer helped generations of beginners get started with tropical fish keeping. The surviving record is slim, but the book’s clear, hands-on approach still gives a good sense of an author focused on hobbyists and everyday care.

by Guenther-Lothar Schott
Guenther-Lothar Schott is credited as the author of Tropical Fish Handbook, a practical guide for aquarium beginners. Project Gutenberg lists that title under his name and identifies the edition now online as the tenth edition from 1953.
The book is centered on everyday fishkeeping rather than theory. Its scope includes tropical fish, goldfish, aquatic plants, and aquarium accessories, which suggests an author interested in making the hobby approachable for newcomers.
Reliable biographical information about Schott himself appears to be scarce in the sources I could confirm. Because of that, it is safest to remember him through his work: a straightforward hobby manual that has remained visible through later reprints and public-domain preservation.
