wetwebmedia list it this way:
Stigmatogobius sadanundio (Hamilton 1822), the Knight Goby. Asia: from India, Thailand, Malaysia and Indonesia. To three and three fifths inch in length. Conds.: freshwater to brackish, pH 7-8, dH 9-19. temp. 20-26 C.
further research of mangroves in singapore, home of the grey knight goby, says salinity varys from 1.0005 to 1.035 depending
on the tides and the season. [35 being marine]. the article said brackish is considered from .5 to 18. how much salt do you need for 1.0005? not that much.
a few other sites polled, say 1 tablespoon to 5 gallons will do.
according to some posts, they arent keen on temps over 80.
even shadier sites say they can be acclimated total fresh or total marine.
the whole point of being brackish is flexibility to survive variation in salinity. eek out an existance where freshies and salties fear to tread.
i dont think it will do as well in a no salt tank. [i wouldnt keep it in a no salt tank] . but he's made it pretty clear we cant guilt him into returning it. and if he's doing everything else right, it probably will be around in 6 months. perhaps when he is tired of the goby being greyish black, he'll chuck it in a hospital tank with salt, start to enjoy the original color of the fish, and become a brackish fanatic.
