little_washu 7 Posted December 26, 2013 Been a long time since I've posted, my Ryukin, Yamato has been doing really well, he's about a year and a half old now. Sadly he's been plagued by floating issues so I have had to keep him on a strict blanched peas diet. Anyways, I figured it would cheer him up to have a buddy in the tank with him, so I purchased and quarantined a beautiful Black Moor who I just introduced to the tank yesterday. The Black Moor, Othello, made himself right at home but almost immediately began chasing Yamato all over the tank. Yamato swam away with great speed at first but over the past day has gotten more and more apathetic about the whole thing and Othello now spends his time headbutting Yamato. I was really confused at first why the new fish would show this kind of aggression towards the established fish, especially since Yamato is larger, but then in dawned on me: THIS WAS MATING BEHAVIOR Yamato might be a female...whoops So I guess I'll just let nature take it's course and hope that maybe if Yamato lays some eggs it may help with HER floating issues a bit. My one concern that I wanted to bring up for discussion (and something I haven't found a straight answer to so far), how do male and female goldfish get along when they're not breeding? Can they coexist happily in a tank? Does this chasing behavior happen year-round? I don't want Yamato to be harrassed everyday all day for the rest of her breeding life so I'm hoping this only happens at certain times of the year. Also, is there anything that can be done to discourage breeding season, like raising water temp, etc? Thanks in advance for your insight! 0 Quote Share this post Link to post Share on other sites
