Ecology Summary - Melanotaenia wilsoni

Language:

Main Ref.	Hammer, M.P., G.R. Allen, K.C. Martin, M. Adams and P.J. Unmack, 2019
Remarks	Habitat is shallow (< 50 cm) comprising small Pandanus lined spring fed creeks over sandy soils with strong lateral connectivity to densely vegetated peat swamp and side-channel areas. Swamp and channel habitats can be seasonal or retract to refuge holes. Water transparency ranges from clear (streams) to heavily stained, indicative of water quality parameters in the dry season including pH 6.0-6.5 (noted also as 5.0: Armstrong 1995), temperature 23-24°C, water conductivity 15-30 ìScm-1 and general hardness and carbonate hardness <10 ppm. Little else is known on the biology of this species other than records of spawning and behaviour in captivity, where it is observed as extremely shy, which is viewed as an adaption to shallow habitat (Ref. 121823).
