An aquarium configured with water salinity between freshwater and full marine levels, typically using a specific gravity of 1.005-1.015 for species like mudskippers and archerfish.
شرح مفصّل
Brackish aquariums bridge the gap between freshwater and marine keeping and present unique challenges: marine salt must be used (not freshwater aquarium salt), regular refractometer or hydrometer measurements maintain target salinity, and water changes require matching the replacement water's salinity. Archerfish (Toxotes) famously knock insects off overhanging vegetation with water jets; creating an above-water land zone is a rewarding brackish setup feature. Figure-eight pufferfish (Tetraodon biocellatus) are popular brackish-kept species requiring gradual salinity elevation from juvenile freshwater to adult brackish as they mature. Substrate of coral sand helps buffer pH to the alkaline levels brackish specialists require.
