Many brackish water fish species commonly kept in aquaria are, to a greater or lesser degree, herbivorous and can do untold damage to a well-planted tank.
Generally, the shopkeeper can probably advise you on which species are brackish which are not and, as with fresh water and marine fish, knowing the water conditions to which the fish are acclimatised in his or her tank is important.

Brackish water is water that is saltier than fresh water, but not as salty as sea water.
As a result, many brackish water fishes are tolerant of changes in salinity, and in fact many positively benefit from similar periodic changes in aquaria.
The term brackish water derives from the Middle Low German word brackwater or possibly the Dutch word brakwater, which is the water of a brack.
