I have one acara currently recovering from an infection i believe was brought on by agression ini my main tank, and one severum that regularlly gets beaten up, regardless of rearranging and so forth. so im thinking of trading them both in (when the acara is fully healed) and getting something that will either stick up for itself, or that looks different and will not get picked on by my true parrot or green severum, which are the two top dogs of the tank, my pike, bichir, and ghost knife are all totally ignored by the true parrot and green sev, so, im not sure what to do, anyone have this same issue, what did you do, any thought, opinions, experiences will be greatly apprecieated
