Melanotaenia trifasciata, Giddy River
Melanotaenia trifasciata, Giddy River is a stream dwelling
rainbowfish from northern Australia (click here for a
general discussion of rainbowfish). This species comes in a number of
natural color varieties, each from a different stream. This particular
strain is from Giddy River, hence its location designation. We acquired this
geographic variant of the species in 1996 from a commercial source. The top photo is a male. The bottom photo is a female.
Size: Males and females reach 15cm (6 in.). Description: Males sport a pastel blue body and orange fins. Females lack pointed dorsal and anal fins of the mature male, are not quite as colorful and do not have deep bodies.Environment: This species tolerates pHs from 6.5 to 8.0 while preferring the higher end (basic) of this range. Water hardness is not critical. Optimum temperature ranges from 20-30°C (68-85°F). Geographic Range: This species has a range including much of coastal central-northern Australia. This color variety is from the Giddy River in Australia's Northern Territory.
Spawning: This rainbowfish spawns like other rainbowfish, laying eggs daily in fine leaved plants or plant roots (click here for a general discussion of rainbowfish breeding). The eggs hatch in about 12 days and the fry can take microworms, vinegar eels or infusoria immediately. Growth is rapid and sexual maturity is reached in about 4 months. Additional
