I noticed yesterday while feeding my fish that I may have had a surviving koi baby from last year. I have a comet that is about 3-4 years old now but is still mostly black with some dark around around his underside. Because of the dark color, I don't see him very often. Lately I've been feeling like every other time I do see him, something is different. Well yesterday I was feeding everyon early before heading over to my parent's house, so the sun was still up high, and I got a clear look at this guy... Definitely a lot of black and dark orange, but this one has more of a mottled look like shubunkins. However what really stood out was half a dozen highly reflective scales across his backside. Now I have seen this is many koi, but I have never seen it in my comets... So it made me start thinking that there are probably TWO black and orange fish in the pond.
Time will tell... I'll keep an eye out to see how big this one gets, and if I ever seen any whiskers. It would be exciting to find out that at least one baby koi has survived in my pond in the last 2 years.
On another note, PetSmart had some black koi for sale tonight (and at 2-for-1!). Many of them had a silverish look to their undersides, so I don't know if this means they will get lighter or change colors in time? I picked out the two darkest ones and thought I'd give them a try. I know comets almost always change from black to orange, but I've bought plenty of koi even smaller than these and they have never done anything but gotten darker once they were put in the pond.
