I'm ordering 4 wild peruvian scalare looking to get a pair to keep in my planted 36g bowfront, the two I pull is what has me thinking. I have a 72x30x25 with 2 sevs, 3 heckelli, a bellycrawler, 3 sd and a melanurus. Some bickering amongst heckellii but nobody bother them and they never bother anybody. The melanurus is over 10" and will occasionally bicker with the sevs and the bellycrawler but nothing serious. The bellycrawler is 10" and in 2 years never harassed anybody. I am also growing out a polleni. Any chance the 2 extra angels will be ignored like the heckellii?
