About
The neon tetra is a small, iconic shoaling characin from the blackwater and clearwater tributaries of the upper Amazon basin in Peru, Colombia and Brazil. Its brilliant electric-blue lateral stripe and red posterior half make it one of the most recognisable aquarium fish in the world. Peaceful and undemanding once acclimated, it thrives in soft, slightly acidic, well-planted tanks kept in groups.
Care
Keep in shoals of 6+ (ideally 10+) in soft, slightly acidic water with gentle flow and plenty of planting. Avoid large or boisterous tankmates.
Diet
Micro-omnivore that grazes small invertebrates and organic matter; feed small dry foods plus frequent frozen/live micro-foods.
