Does anyone think that a small school of JD's to go with my current JD would be a better idea than a Festae? He's currently the only fish in his tank (other than my bristlenose pleco), so I'm worried especially about him being aggressive to other fish that look like him. But maybe more JD's is a better idea than getting a Festae that's a bit smaller than the JD and growing them up together (measured my JD today, and he's 6 inches on the dot).
