Hi guyz,
I have one silver arowana in my aquarium... I like to introduce another tankmate for him.. So plz guyz, give some idea for another fish
5(f)L X 2(f)W X 2(f)H
150 US gallons (aprox)
currently have 1 silver aro (2feet aprox)
I agree.....Arrowanas should be kept in an 8 foot tank preferably bigger. The general rule-of-thumb is the tank's width should be 2X the length of the adult fish and the tank's length should be 4X the length of the adult fish.
Going by that formula and an adult Arrowana , a tank of 6 feet width and 12 feet length is best.
