藍美人

Melanotaenia lacustris — Blue Rainbow

Melanotaenia lacustris, the Lake Kutubu Rainbowfish or Blue Rainbow, is one of the most vibrantly blue freshwater fish in the hobby, endemic to Lake Kutubu in Papua New Guinea. Its brilliant turquoise-to-deep-blue coloration intensifies with age and under good lighting. An active, peaceful schooling fish that does best in groups in spacious, well-planted aquaria.
