A: Our fish are kept in 6.8 pH (New York City tap) water, 88F (bare-bottom tanks only), and 50 TDS (hardness). If your discus are co-housed with plants or tank mates, these parameters may be adjusted accordingly. For planted aquariums, especially those containing fragile plants, we recommend a temperature no higher than 83F. For aquariums containing hardier plants such as swords and anubias, 84-85F would be reasonable.
Q. What water parameters are your fish kept at in your facility?
