I love koi ponds, I have one in my yard with a pet koi named Spot!
I see. The koi's pond design can affect the health of the koi.
Oh really? It's made of mostly stone with some plants. Is there anything else you can tell me about kois?
Yes! Japanese koi breeders mixed traditional koi with wild river carp known as Indonesian longfins.
Oh really that's pretty cool? I think the Japanese call their koi, dragon carp?
I do not know but speaking about dragon carp, they are also known as butterly koi or longfin koi. These are ornamental fish with their elongated finnage being a notable point.
That's pretty cool to know! I wish I knew what inspired people to call creatures dragons.
Typically,  a dragon is associated with having scales or spits fire and have serpent or reptile or avian traits. Many cultures feature dragons in their myths.
