Description
Melanotaenia ajamaruensis is a rainbowfish from Papua New Guinea, known for its similarity to the popular (and quite closely related) Boeseman's rainbowfish. These beautiful schooling fish have a similar bicolour pattern to the Boeseman's rainbow but are distinctly more orange than yellow, and have better developed lateral striping.
These are juveniles around 2" long that are just beginning to develop colour.
