People grow vegetables or fruit in their gardens, and may keep chickens or other animals. Indoors they may have a fish tank, but it is purely ornamental. How about an indoor Shrimp Garden ? An average sized fish tank should fit a good amount of shrimp. They are aggressive towards other fish, so you would keep them on their own. There must be a business in selling a tank with shrimp seeds and feed, exactly the way people sell tomato seeds and fertilizer – and you don’t need a garden to buy the tank !

Shrimp is a term used to describe about 2000 species of small aquatic animals related to crabs, lobsters, and crayfish. The site here might help pick a variety for growing indoors. Aquarium hobbyists keep shrimp to eat algae and detritus, but those species are not the eating kind.

They are already farmed commercially (see here) so it is possible and commercially viable – although they grow them in the sea / rivers rather than in tanks. They are even farmed organically. The genus they use is Macro-brachium. I saw a mention that they take about five months to grow up to eating size. The only question remains as to whether they can grow in a small aquarium.

Has anyone heard of this being done before ? Is there a good reason why this wouldn’t work ? What about crayfish ?
