๐ŸŸ Guppy

A small, hardy livebearer from South America that comes in endless colour strains. Easy to keep, but it breeds so fast that population control needs a plan from day one.

๐Ÿ‘ Beginners and families who would enjoy watching births and growth, and anyone curious about selective breeding.

โœ‹ People with no plan for surplus fish, or who want just one or two fish that never multiply.

๐ŸŸ Neon tetra

A tiny South American schooling fish with an electric blue stripe and a red tail. Kept in a group of ten or more, it turns a planted tank into a moving ribbon of colour.

๐Ÿ‘ People who want a planted aquarium with a shimmering school of fish, and households looking for a quiet indoor pet.

โœ‹ Anyone hoping for an interactive fish, who tends to skip water changes, or who wants to keep just one or two.
