The set-up must have exposed land areas. A bank or beach made of sand or mudflat mud is suggested but you could use partially submerged bog wood It’s also essential that the atmosphere outside the water is very humid and has the same temperature as the water. A tightly-fitting lid is needed as it will also prevent the fish from climbing out of the aquarium . If you want to grow plants use species that can tolerate brackish conditions.
The set-up should have an efficient filter as mudskippers are greedy, messy fish. Although the species has been recorded in both freshwater and full marine conditions in nature it is primarily a brackish animal. Marine salt should thus be added to the water until a specific gravity of around 1.005 is achieved. Any of the commercially produced marine salt “mixes” are ok to use.
Temperature: A warmth-loving species. Aim for air and water temperatures in the range 77 – 86°F (25 – 30°C).
pH: 7.0 – 8.5. Mudskippers will not do well in acidic conditions. Consider the use of crushed coral or other calcareous material to buffer the water if necessary.
Hardness: 10 – 25°H
