*** A footnote to this entry. Frank Stone started out a major disbeliever that marines could ever be kept successfully in small home aquaria, and cast serious doubts on the credibility of those who proposed such things. Ultimately he landed up putting a large marine tank on full display in his Tooting pet shop and selling Kraken products.
