are dats freshwater? any other info?

[Jesse]

Datnioides pulcher (wide bar) are freshwater and get around 40cm.
Datnioides microlepis (Indonesian) are freshwater, and get around 45cm.
Datnioides undecimradiatus (thin bar) are freshwater, and get around 40cm.
Datnioides campbelli (New Guinea) are freshwater and breed in brakish, and get around 32cm.
Datnioides quadrifasciatus (silver) swim between freshwater and brakish, and get around 30cm.

That's my understanding as well. Max size may be understated for D. pulcher as I've heard of specimens that are pushing 24 inches (60 cm).
