Within a short drive from Darwin (270km for the tris) you can find
Melanotaenia splendida inornata, M.australis, M.solata, M.mccullochi
M.trifasciata, M.nigrans, M.exquisita, Pseudomugil gertrudae, P.tenellus, P.
cyanodorsalis, P. inconspicuus, some nice glassfishes, gudgeons, gobies, and
hardyheads.
If you come here I will draw a mud map (that means give directions) for
their locations for you to go and see the habitat for yourself.
