Aggressive Uaru?

[Nove Sedici]

Very interesting, I was under the impression they would be mellow as well. Mine are pretty peaceful most of the time, but when I feed, they act like the food is their eggs and they basically guard it

I know 2 people with uaru’s and in both cases they are mellow indeed. Ofcourse there always is a difference between individual fish but this difference in behavior is huge.
