How did they look when they fought, were one of them just very occasionally doing a biting motion to the other aro and the other aro seemingly not minding it at all? Or were they like actually fighting each other.Mine was fighting with each other had to separate eventually at 8+ inches
They will grow to be big fish. They may not reach their max size of three feet, but they should grow at least a little more than two feet. That means end to end, they will be longer than your 75. Hard to believe, isn't it?Wikipedia said:This fish has relatively large scales, a long body, and a tapered tail, with the dorsal and anal fins extending all the way to the small caudal fin, with which they are nearly fused. It can grow to a maximum size of 90 cm (35 in). Unlike the black arowana, the silver arowana has the same coloring throughout its lifespan.
