hi i added a new (hopefully female) curvicep cichlid to my tank today and my other one (been told male) went up to the bag and looked at the new cichlid, after i let her out he went up to her and they swum near each other but now he just chases her around doesn't attack as for say just chases... what could this mean? good or bad? he's not as shy now with her in there and she comes up to the glass when im near and hes not around...
