Since the population of wild Arowana has decline and near extinction many farms are breading Arowana in Malaysia, Indonesia, Thailand and Singapore. Due to the great demand world wide the Arowana are currently classified as an endangered species threatened with extinction in the Convention on the International Trade in Endanger Species of Wild Fauna and Flora (CITES). The Green Arowana still available in abundance in the wild and also considers as an endanger species. There is Green Arowana with purple based color and unique pattern also highly demanded and fetch very high prices. The Arowana fry size is about 2 inches when it starts swimming freely. Usually Arowana achieved a size of about 14 inches after one year old and 18 inches after two years and achieve maximum size of 36 inches after ten years old.
Since Arowana grow very fast in the first two years the minimum size of aquarium recommended is 48’X18”X18”. Larger size of aquarium will reduce water replacement frequency and provide more space for Arowana to swim.
Arowana is an acidic fish and love clean flowing water with PH 6 to PH 7. PH above 7 will make the color less attractive and induce slower growth rate, for fish age below 12 months the grow rate is about one inch a month. PH below 6 on the other hand will make the Arowana become more aggressive and uncomfortable. PH below 3 or above 10 endangers the Arowana life and must be avoided. Red Arowana needs more acidic water PH 5 to PH 6.

In the aquarium due to the limited water quantity the PH reduce from 7 to the lower PH due to Arowana waste and by product. To improve the PH regular change of water is required. Regular changes of water also improve the water quality in improving the minerals level. For 48”X18”x18” aquarium it is recommended that 30 % of the water to be change every one week or whenever the PH goes below 6. The change of 30 % of the water is recommended so that no drastic change in PH, water temperature and chlorine content will affect the Arowana drastically.
The used of good PH measurement equipment is highly recommended. Excellent water quality free from unwanted virus, bacteria and parasites is the key elements for healthy and long life Arowana. Almost 90 % of Arowana in Aquarium die due to poor water quality, careless during water changing process i.e. adding chlorine tap water to aquarium without applying correct amount of anti chlorine and feeding too much food. Too much food reduces water quality and will encourage bacteria and parasites growth and develop potential disease.
Arowana need minerals, vitamins, good quality water and sufficient balance diet to be healthy. The used of dried sea almond leaf to provide natural organic acids, minerals, vitamins and hormone is highly recommended.
