I had successfully grow Monodactylus species [argenteus and sebae] from 3-5cm to
10-15 cm in 100% freshwater filtered over coral gravel. I kept them for over a
year before their fast swimming combined with larger&larger size bother other
fishes too much so that I had to give them away. Also I had read somewhere that
for some species of brackish and marine fishes what is important is hardness and
some magnesium and/or potassium and other substances [but not large amount of NaCl
is necessary].
