Hey , I'm kinda new to monster tanks , I am starting with an arawana . I got him at about 3 inches two months ago and now hes right at 9. I have him in a community tank with some smaller fish but his new home will be a 125 gal. tank . How big do you guy think he will get and is he going to eat me right out of my house ? What other monsters are compatible with him. Hope to hear from someone soon .
