so the stocking is in my signature, starting a few days ago my two smaller pictus starting swimming up the side of the tank instead of on the bottom like they normally do, i have had them for about a month and a half and after quarantining them for about a week i added them into my large tank with my larger pictus. there was the expected little tuffles but then they were fine and everyone stayed down on the bottom and was active for the last couple of weeks, now one of the small pictus that is swimming on the side of the tank has pretty much its entire tail chewed off, but its feelers are still completely intact, its only his tail that someone is tearing on. who do you guys think could be doing this? the only thing that has changed was the re-addition of the argentea after a time-out in the quarantine tank to give the angels time to settle in so he would leave them alone, i haven't seen him bother anybody since i re-added him and if it were him i would think he would go after the feelers not the tail, in the past whenever a cichlid went after any of my pictus they always went after the feelers but even then didnt do this much damage, i cant for the life of me think of who could be bothering them, i never see anyone going near them, and i would think if it were the larger pictus the trouble would have started from the beginning not suddenly a few days ago, what are your guys thoughts?
