The livebearer questions have been answered, but the carp and koi...if they're are anything like regular old goldfish...the males will get white spotty looking things called tubicules on the gills...they kinda look like little pimples...almost like ick, but it's not...not to mention they way they'll chase the females around when the water temp goes up...they literally beat the eggs out of her...it's actually kinda disturbing to watch :::covers eyes:::

Hope this helps! And welcome to the tank!
