+1, idk about there wild behaviors though, I haven the read of anything like thatThat's one serious wow... and a first for me. Do you keep them together of brought them together for mating? I see their fins are somewhat tattered. I wonder if this has to do with the mating behavior.
I thought jardini can rarely bring themselves to tolerate any tank mates, let alone another arowana, far, far less so another jardini.
Don't they come together in the wild only for mating?
