Ideal water parameters for Yellowtail Coris

Marine fish are highly sensitive animals with very specific care requirements. Most all saltwater species will require similar water conditions, designed to replicate that of natural seawater. Ammonia and nitrite levels should absolute zero, temperature at 76F to 80F, and salinity at 1.024 to 1.026. Although some fish are tolerant of lower levels of Nitrate, the goal in every aquariums should be to keep Nitrate as close to zero as possible, and certainly under 20ppm. Finally, maintaining a stable pH of 8.0 to 8.4 is desired. Achieving this is made easier by monitoring alkalinity, which should be kept at 8-12 DKH, and calcium, which is targeted at 400 to 460ppm.
