In giant gourami fish farming, good soil types for giant gourami fish ponds are:
- clay / clay,
- no pivot
- enough to contain humus
The type of soil used for maintenance can withstand large and non-leaking water masses so that ponds / walls can be changed.
The slope of the land which is good for making the plantation area ranges from 3-5%. The slope serves to facilitate the irrigation of ponds by gravity.
Giant gourami fish can grow normally and optimal if the maintenance location is at an altitude of 50 - 400 m above sea level (above sea level).
The depth of fish rearing pond that is good for the growth and physical development of giant gourami fish is the depth of the pond around 70-100 cm and has a good flowing irrigation system.
In traditional giant gourami fish rearing in special ponds, the required water discharge is 3 liters / second, while for giant fish gourami maintenance polyculture ideal water discharge between 6-12 liters / second.
Degree of water acidity (pH) which is good for the growth and development of giant gourami fish is between 6.5-8.
Swamps in the deep, low-lying lowlands are the original habitat for giant gourami fish. One of the factors that distinguish between lowland and highland is the temperature of pond water.
Giant gourami fish will grow optimally at a temperature of 25 - 28ºC. Giant gourami fish are very sensitive to low temperatures so that if kept in water with temperatures <15ºC, giant gourami fish are not well developed and fish growth will be disrupted.
