So I have a pair of mated angelfish. Been Mates a full year. They started showing tubes but there was an aggressive lab in the tank and nobody (even my Kribs) were spawning. The lab is now moved to a different tank. HOWEVER the angelfish, who do EVERYTHING in tandem, are being odd. The male appeared to be kissing the side of her body and she swam away and then when she came back he lunged at her, touching her body, a few times, until she swam away. I hope they aren’t turning on each other. Are they? Or is this mating?
