Yeah, right on. I forgot to mention that they are bullies, not horribly mean but like to push most other top and mid water dwelling fish, especially other arowana.Thank you for the reply. Got him to about 6 inches and ended up trading him in :/ his behavior became bullish and he ended up spooking my silver aro in the middle of the night... I left just enough of a gap where I feed them and found my silver dead on the floor not far from that spot. Although it was partially my fault, I made the tough decision to let him go. He was an awesome fish, but his hyperactivity became problematic for my other stock. Wouldn’t mind owning another later down the road!
It sounds like blaming the African aro is a supposition but it is one of the likely ones. Silvers, and all aros, are accomplished jumpers. Except for the Africans, arowana jump for livelihood.
