Okay here's the story... I have 2-30 gallon tanks. In one tank is Saki(male patternless) with Jiffy(female), and in the other cage is Skip(male high yellow) and yin yang(female). They are all about a year old except for Yin yang who is 11 years old. Both sets of 2 have been living together for about 6 months. There was never any issues. They got along great. Just recently though, in both tanks, the males have been going after the females. Saki grabbed Jiffy's neck and she foought back grabbing him. She also has some cuts on her body from him. Is this normal mating? and will it stop? At the same time Skip has been chasing the 11 year old yin yang around, and she has been attacking him with her tail. So I figured I'd try to switch the females. This worked in saki's tank, but not with Skip. He went after Jiffy. Saki was okay with yin yang however. So then I put yin yang back and Skip went after her worse than before, so she is now in with saki, and Jiffy. This seems to alleviate some of saki's attacks on Jiffy and he has seemed to calm down. But i feel like he will do It again, but I feel bad Jiffy is scared in the corner of the cage and bruised. What do I do? Should I just leave the females together and separate the males into 2 more cages?HELPPPPP!!!!
