These fish are often regarded as essentially brackish, but can thrive in fresh, brackish, or even
full marine conditions if acclimatised gradually. Although often considered beneficial, the addition
of salt to the water is not essential as long as the water is hard and alkaline. If salt is added, it
should ideally be marine salt, rather than general aquarium tonic salts. The tank should not however
be routinely salted if it is a mixed community containing soft water fishes.
Many colour varieties are available - including silver, mottled and speckled or "dalmation" varieties.
