I began keeping aquariums as early as I was nine years old. Since then, I kept many aquariums and lots of fish, plant and invertebrate species. My favorite fish family is of course cichlids with their fascinating behaviors. My relatively new area of interest is low-tech natural aquariums as almost self-sufficient ecosystems that are I think ideal models for sustainable life.
