Hey, first time poster here. Lurking pretty heavily for the past 7-8 months, had been planning on waiting till I could get a decent temporary setup and buy some tosai from a reputable location... that is, until I was in Petsmart and saw this "black koi" all by itself trying desperately to get into the adjacent koi tanks. After getting permission from the wife, I grabbed this little guy and a friend in an adjacent tank and whisked them away from their life of solitude in an overstocked tank. They're still in a tank for now, but they'll soon (as in, within the next few weeks) be in a 400 gallon above ground pond (that will later be upgraded).
I know they're probably not ever going to be show quality, but they've got spunk.
Both are about 2-2.5" in length.
Maybe a karasugoi/magoi (are those the same thing? Google has certainly been unrevealing). I think the white one is maruten kohaku of some variety, and has a pretty sheen to 'em, too; not sure what to make of a fin with hi on it though, outside of excluding it from being tancho.
Thanks for letting me pick ya'll's brains!
