What size tank does a 20 cm silver arowana need If the breeder only breeds for a short time, he can choose an 80 cm long fish tank. Because the 20 cm silver arowana can live well in an 80 cm long fish tank, there is no need for a larger fish tank. However, if breeders want to breed for a long time, it is recommended to choose a larger fish tank. Because the silver arowana grows fastest at the stage of 20 cm, and their body length can reach about 60-70 cm in adulthood, and some larger ones can grow to 100 cm. Therefore, it is suggested that breeders prepare a fish tank of about 120-180 cm for them, so that they can have enough space to develop their body shape.
2. How to raise Arowana1. Water temperature: Arowana likes a higher water temperature, and breeders need to keep the water temperature between 25-28 ℃. In this temperature range, they will also grow faster.
2. Water quality: Silver Arowana prefers weak acidic water quality, and it is necessary to keep the PH value between 6.5 and 7.5 when raising at ordinary times. Silver Arowana likes clean and refreshing water, so it is best for breeders to change water once every 3 days, and it is best to control the amount of water changed every time in one third of the total water volume.
3. Feeding: Silver arowana likes live bait, so breeders can feed them more live bait. Especially for silver arowana below 20 cm, it is best to feed only live bait. When they grow to more than 20 cm, they can be fed with some synthetic feed.
