Any comments out there? Well, with 3 seperate pairs of wild caughts with mixed sources, I'm really thinking that there might be something to the environment/parameters that people are keeping there fish in, rather than a common behavior. As to your comparison of species, the A. njisseni are described as being of the macmasteri complex and for certain the A. macmasteri that I have are extremely timid. The most aggression that I've viewed in apistos is with A. standachneri and that too was largely associated with other apistos that were in the same tank (A. viejita).
