Overview

A true nano fish at around 3 cm, it thrives in a heavily planted tank from about 40 litres. Keep it at 22 to 26 C and pH 5.5 to 7.0 in soft water. Keep one male with several females, as males spar over territory, and avoid boisterous tankmates that outcompete it for food. It usually needs small live and frozen foods such as microworm, baby brine shrimp and cyclops.

In the wild

The red melon dario is a tiny nano fish, with dominant males glowing a solid orange-red and females staying a plain grey-brown. It lives in shallow, plant-choked forest streams. Males hold small territories among the stems and moss.
