icthyophile;507884; said:I concur w/ Phil (Oddball). Datnioides quadrifasciatus, aka "silver dat" in the U.S. and "American tiger" or "AT" in Singapore, occurs in FW to brackish conditions (SG 1.000 to 1.010). If you're going to keep silver dats in FW, I'd recommend adding crushed coral to your substrate to ensure that the pH stays alkaline. IME, they will suffer and could die if subjected to prolonged periods in soft, acidic FW.
gotta agree lost 2 silvers that were in real soft acidic water. the 5 in the higher ph lasted longer but a 5 star cichlid and flowerhorn took them out
