I've been interested in them for a few months now and I have searched the forums and found the scattered info. But what are their personalities like? Are they active? aggressive? How would they be (in the future a few months at least) with a black aro, maybe a stingray, A few Dats, a Tigrinus, Ornate or Endli Bichir, and Maybe a Johanna or Cobra Pike cichlid? O yea the tank would be 6' long 2' wide or 6' long 30" wide. Thanks for any help.
