Hi guys and gals. Im a newbie getting back into the fish game after a 12 year absence, living in Australia. I need some help deciding on what is best in keeping with arowana's. I was thinking Dovii's or gars, though im not sure in regards to temperment. I want an agressive tank, but still need happy residence. Any thoughts, on something that will give attitute, and also on something with a talking point as a bottom dweller.
Looking forward on some expert advise, and thank you in advance.
