Red tapajos for reference. My aimara behaves very similarly, will snap at any net or equipment or hand if I'm taunting. Constant flaring through the glass but leaves both bichers I have in there with him completely alone. Also leaves the temensis I have in there and sometimes has a scuffle with the Mala. However the dorado I have housed with him are nemesis enemies and they go at it from time to time. They are around similar size and the dorado is too accurate with his bites that always end up damaging the aimaras eyes. After I've placed the peacock bass in there as a dither, the aggression has died down almost altogether.
