Interesting how life experiences unfold sometimes. A few months ago I was given four fish which were identified as KOI. (Three Orange with white spots and bands and one primarily white.) Unfortunately, one of the orange ones disappeared from the outdoor pond almost immediately but the remaining three proved to be quite prolific producing numerous fry (young fish). When I say numerous I mean hundreds of them! (The parents, and other predators, consume the young ones and thus keep the pond population down.)
I was surfing the internet for images of KOI fry (to rule out the possibility the offspring might be another species previously habituating the pond) when I began to doubt they were KOI at all because they did not have the mustache like “barbels” that KOI do.

Later a friend of mine checked with a pet store and was advised they were a specialty bred Goldfish called Fancy Comet. Here’s some 411 on Comet Goldfish:

You know, it doesn’t really matter what they are because watching them is rather relaxing.
ANYWAY, no big deal, just thought it peculiar: losing Comet my long time geriatric pet cat then inadvertently ending up with a pond full of Comets.
My best to you and yours, Lew
