Wow that is a stunning sire. I am 100% little Zulu is going to be spectacular with a dad like that. Don't be too worried, sometimes they go through the strangest phases as they grow up. I have a nosy be that was completely light lemon yellow for a couple months and is now more and more turquoise, so they definitely go through changes as they mature.
hahah nope, definitely not the friendliest, likes to keep to him self and hates being handled, runs away from my hand even when im offering him food!. thats why i nicked named him Mr.grumbyscales.
