Aquarium setup

At 12 inches, the four-eyed fish is a comparatively large fish for the aquarium. In order to keep them "happy,” keep them in groups of six or more, and never maintain them singly or even just as pair. They generally spend all their time at the water surface. These considerations dictate that the aquarium for four-eyed fish needs to be at least 48 inches long (90 gallons), but preferably 60 inches long (150 gallons) to accommodate six to eight four-eyed fish, as well as some other fish in the same aquarium. As they are surface-swimming fish, the water level in the aquarium needs to be dropped 12 inches from the top but should be 12 inches deep, dictating an aquarium with a height of 24 inches. Four-eyed fish are good jumpers, so the aquarium needs a tight-fitting cover.
The aquarium bottom should be furnished with a 3-inch gravel bed that can be overlaid with some smooth rocks or even bogwood. If one is to include mudskippers (Periophthalmus spp.) in this setup, the rocks and bogwood would need to break the water surface in one front corner of the aquarium to give a good view of the mudskippers that are normally out of the water most of the time. However, a large water surface should be maintained for the four-eyed fish. It is hard growing regular plants in a brackish aquarium, but one could try some macro algae or even some small mangrove plants that would need regular trimming to keep them within the confines of the aquarium.

While sea water has a specific gravity of around 1.020 to 1.024, brackish water with a specific gravity of around 1.005 is adequate for maintaining four-eyed fish. However, finding a hydrometer calibrated to check this specific gravity level might be difficult. Brackish water can be made by adding 2 level tablespoons of marine salt per gallon of water. Some hobbyists may elect to use aquarium salt or the even cheaper cooking salt, which is just sodium chloride and does not contain all the trace elements found in sea water. The water parameters of a brackish aquarium are generally alkaline and hard (pH: 7.5 to 8.5, dH: 12 to 20), which fortunately can be easily measured.
The brackish aquarium does need a good filtration system, which can be provided by a large external canister filter with a large colony of nitrifying bacteria (Nitrosomonas and Nitrobacter) to convert the fish waste, such as ammonia, first to nitrite and then nitrate. Large fish produce a lot of nitrogenous wastes that can adversely affect the fish if their levels are allowed to build up.

Additionally, regular partial water changes (20 percent) with fresh brackish water are needed every two weeks to remove accumulating nitrates to maintain good water quality. The canister filter return pipe also provides a nice current of water that is necessary in this tank. A heater thermostat or two is needed to maintain the water at a temperature of 77 to 86 degrees Fahrenheit. Adequate lighting can be provided by fluorescent tubes even if mangroves or macro algae are growing in the tank.
The four-eyed fish greatly appreciates live insects taken at the water surface. The garden is a great provider of insects and other crustaceans of every variety, though the easiest to collect are probably woodlice. Lifting any old piece of wood in the garden and lightly tapping it inside a bowl dislodges a multitude of different-sized woodlice that are appropriate food for these fish. These woodlice are crustaceans that have properly invaded land without the need to return to water in order to breed. Because they feed on dead leaves and stems found in the soil, there are hundreds of these half-inch bugs around compost heaps.
Fortunately, four-eyed fish will also feed on floating food sticks, pellets, and even flake and frozen foods. All these various types of foods are generally taken at or near the water surface by the four-eyed fish and not at substrate level, while sailfin mollies and orange chromides will happily take food mid-water and off the substrate.
