same time, you need to use a humidifier to regulate the temperature of the aquarium to around 25 degrees Celsius. In this way, the fish can get a suitable living environment. Configure the sea water Generally, the finished artificial sea salt dissolved into fresh water, this is the common use of artificial seawater. Here are some things to watch out for, Do not use metal containers when mixing seawater. Take care to measure the water quality of sea water regularly every day, put the fish down after quality of the see water is stable. After making see water successful, cycle filtration, heating and oxidation should be initiated. Artificial environment This fish is more often active in seagrass areas, so the artificial environment should have a certain amount of seagrass. At the same time, some sand is required to create a more realistic eco-fish tank. Reproduction Glassy sprat reproduces through sexual propagation, ovipara, and in vitro fertilization. Each female glassy sprat can lay tens of thousands of eggs and they scatter them freely in the sea (Prince, 1907). Male fish discharge a lot of semen after the female lays eggs, which causes the water to turn a different colour. Glassy sprat roe have mucus on the surface of their egg membrane and can be stuck to rocks, moss, and water grass. While their hatching success rate is low, the number of new offsprings born each year is a lot. The hatching time of fish eggs is variable, ranging from 1 to 5 days. The eggs of sprats are translucency, extremely buoyancy, and delicacy. Their ova are 1.016 mm in diameter and spherical. The capsule is fragile, yet the transparent, colourless yolk that almost entirely fills the capsule has delicate lines or reticulations, as if the yolk were not separated into spheres The anal opening is a four-fifths distance along the underside of the body and the basal portion of the tail (Prince, 1907). The eggs and larvae of the glassy sprat are plentiful in the sub-tropical waters of southern Queensland during late winter and early spring (June–October), when the average monthly sea surface temperature ranges from 21 °C to 23 °C (Ward et al., 2003). The females spawn an average of one per week. The hatching time of fish eggs is variable, ranging from 1 to 5 days. After hatching, the baby fish will use estuaries for food and shelter, such
