I have a small aquarium at work that I stocked with 4 cardinals. I've never had any luck with them in previous tanks, mostly because I think the other fish were eating them and I was too stupid to have predicted that. ("they won't eat each, my fish aren't canibals).
So 3 months later, my little cardinals appear happy and healthy and have really come out of their shells, to the point where they're becoming terratorial. I was shocked. I have never seen this behaviour before with cardinals. My guess is that perhaps the ones I've had in the past in community tanks have been too busy trying to avoid the jaws of a large angelfish to exhibit any natural cardinal tendencies.
Has anyone else seen this?
