Here are some things to watch and learn from.
Your showa is very white at this age. usually the white looks somewhat like 2% milk. You can learn what this bright white means as this fish ages.
It appears that it may be female from the body shape. Yet the red is so bright red that one would wonder if it's male.
so what will this white and red mean as it ages?
Be sure and keep track of your PH while it grows.
I could tell you the answer to all these things to watch for but by not learning as your going you wouldn't get anything out of it. Lil dude is right, you can always learn something from any koi whether it's $15.00 or $1,500. Just like on a coin there are always two sides......genetics and water ( your skill )...
thanks for posting!
