Freshwater Aquarium Fish Profiles

Every fish in the reference — adult size, minimum tank, temperature and pH range, temperament and diet, plainly laid out.

Species profile

A hardy, long-finned labyrinth fish that breathes air — best kept alone in a heated, filtered tank of at least 19 litres (5 US gallons).

A tiny, peaceful dwarf shrimp that grazes algae and biofilm — colourful, easy to breed and perfect for nano planted tanks.

Peaceful, armoured bottom-dwelling catfish that forage the substrate — social, hardy and best kept in groups of six or more.

A tall, graceful cichlid that needs a deep tank — a beautiful centrepiece, but semi-aggressive and a threat to very small fish.

A hardy, colourful livebearer that breeds readily — beginner-friendly, but males and females together will multiply fast.

A slender, eel-like nocturnal loach that sifts the substrate — peaceful, social and best kept in groups over soft sand.

A peaceful, plant-safe aquarium snail that scavenges leftover food and algae — a hardy cleanup helper for the community tank.

A tiny, iconic schooling fish with an electric blue-and-red stripe — peaceful, soft-water and best kept in groups of six or more.

An extremely hardy, fast-swimming striped schooling fish — tolerant of cooler water and ideal for a first cycled community tank.
