i have just brought my beloved king kong parrot from another tank into my established 40 gallon (for now) cichlid tank where my 4" gold severum is the unchallenged and benevolent king. the severum has always been very peaceful with his tank mates, until now. he has been fairly constantly and aggressively chasing adrian brody (the parrot) since i introduced him to the tank 6 hours ago. should i be worried that he could do real harm to my parrot, or should i give more time for this territorial dispute to settle down.?
