Okay... Do you not know what an overstocked tank looks like? Plus, that is a GREEN ASIAN arowana not a jardini arowana which are from AUSTRALIA and have completely different temperaments.
I just set up a 180 gal and i am putting 2 silver and 1 jardini aro in it. Will that be large enough for them? i have a 220 gal but its not set up and i was trying to make it a ray tnk.
Besides, I've known a case of 20" Green killed a 22" Jardini. So which one do you think has a better temperment? BTW, it's not the tank overstocked. It's the filtration system that's matter
