>I even have a small pair of A. borelli that raised fry in a 10 gallone >tank full of gardneri, which are relatively aggressive for killies. The gardneri are one of the few that I think might work as dither fish. I have kept some with apistos, but they slowly disappeared. Actually, the aggression level of these fish is very low as opposed to some of the other genus of Killies. I judge the intra-specific aggression of some of the other Killies to be higher than that seen in Siamese fighting fish males toward other males. _______________________________________________________
