I have never seen a wallago before and I think I know one user sell them as juvies on Facebook but I will rather tell it, but I am planning to get two bonded pair toman snakehead & one male wallago leerii and introducing them as juvies at the same age in the new house —> in the future. Is there something I still need to consider importantly? What size should I get? Should the snakehead size be a bit lessen than the wallago? Should all 3 be at the same size? Will bonded pair lessen the aggression / risk than solo because the other one will focus on the other snakehead rather than wallago? What tank size is recommended? Which is better females or males to coexist with bonded pair toman snakeheads? And more and so on... Ok have anyone ever experienced keeping wallago leerii & toman snakeheads together and what lasted please explain carefully! Thanks.
