Emperor Tetra (Nematobrycon palmeri) 

Originally found in Columbia, living in small, slow moving rivers and tributaries; nowadays mostly bred in captivity.  The emperor tetra is a good addition to a community set-up with other small peaceful fish. It is lively, peaceful and colourful; it is also a hardy little fish, though larger fish may consider it a tasty snack.  Like most tetras, these are best kept in shoals of six to ten, and will create an attractive display.   They may breed in the right conditions, scattering eggs over plants; the eggs hatch in around 24 hours (if they don’t get eaten by the parents!)

Size (fully grown): 3.5 – 4.2cm (about 1.5″)

Water temperature: 23 – 27C

Water pH: 5 – 7.5
