Musa River bends’ edges, PNG

Sponsored by

Papua New Guinea, Northern Province, Ijivitari

This is a reproduction of a natural biotope in the Safia Valley of Papua Nuova Guinea.

In a marginal, shallow part of one of the Musa river bends, the slow, steady current smooths and gathers the rocks and driftwood, which pile up with each other. In the ravines that are thus formed, Tateurdina ocellicauda and Pseudomugil furcatus hide, finding thier ideal habitat among the lush and dense aquatic vegetation that develops in the area.

Aquarium information

Aquarium description

Set-up date
April 2021
Aquarium decoration

Sandy bottom: inert, for building purposes and consisting mainly of phyllite silicates, gneiss, crystalline schists, of a geological composition similar to that of the region, in order to simulate the erosion of the upper rocks and the slow accumulation of insoluble sediments.

Rocks: commonly used by aquarists, small and medium-sized granitic rocks chosen in various light and dark colors with a prevalence of beige colors.

Woods and roots of common aquarium use.

Aquarium equipment

Two high-capacity air filters and a 150W heater.

Fish care

Weekly 20% water changes with osmosis and regular maintenance.

Abundant feeding with live food (Daphnia magna, Chironomus larvae, and tubifex) along with dry food.

Fish:

  • Tateurndina ocellicauda
  • Pseudomugil furcatus

Aquatic plants:

  • Leptochilus pteropus
  • Vallisneria sp.
  • Ceratophyllum demersum.
Plant care

Daily and weekly doses of iquid fertilizers.

Water care

Bottom syphoning and varied maintenance.

Comment by the expert

Greg Martin: Limited footage of the natural biotope – points deducted. Hornwart does not occur in this location – points deducted.

Peter Unmack: All of the BIN data were from a previous submission. The plants didn’t seem to be a particularly close match, especially given the habitat video showed almost no vegetation in the stream. The aquarium looked quite nice, but it was unclear that it matched the wild environment.
