How to start a silver arowana breeding tank?
It is almost impossible to breed arowana in a tank due to lack of space. You’ll need a very large tank for that purpose (yes 500 can be considered, the larger the better). Arowana breeding process, regardless their colour is done in special garden pond where there are plenty of space and soil. Arowana is a mouth brooder (which means they store eggs in its mouth). It’ll take about two month before the fry emerge and by that time, they are large enough to take care for themselves. Good Luck!
