So I picked up 2 electric blue acaras today and they were bigger than I thought... around 5 inches my copies are about 1 inch and my other severums and geos are 2 inches.... do I have anything to worry about?
It's difficult to predict the aggression level of any particular Cichlid. That being said, the EBA is known to be one of the less aggressive Cichlid species.
Although relatively peaceful, the EBA will likely eat any tankmate it can swallow.
