wui39 Posted December 20, 2005 Share Posted December 20, 2005 I've noticed that during the day and when the lights are on, my arowana behave very territorialy. As soon as its dark and there is only a LED night light, they become very social with each other, swimming in a group. Any explanation as to whythis is?

Cuong Posted December 20, 2005 Share Posted December 20, 2005 How big are they? If they're still young it might be that you're confusing territorial behaviour with the pecking order behaviour associated with colonies of fish. Although I don't think arowanas formed colonies maybe the young do? At night they're probably all sleeping, and it's more secure as a 'colony'.
