Hey so ive had a Nemo koi male that I planned on breedingg for quite some time now and hes never behaved like a normal male. no bubblnest, no tale wags at females, not aggressive at all, and rarely ever flares. I moved him into my soririty to see what would appendix and he’s much less aggresiv then my girls! He’s in there permanently now because it works. Any ideas why this is working? He has no sicknesses or illnesses. Temp is 80 degrees.
