Orandas are the gentle giants of the goldfish world. They have the potential to grow VERY large. Some have more wen than others. Some carry a full "lionhead" type of wen - others carry it as a "tophat" only. It is all genetically decided.
Feeding higher amounts of protien can help develop a wen - hense the special Hikari foods for wen development. They are heavy on the protien. You can use these or other sources of protien. There are many. Feeding a diet heavy in protien will only help develop a wen if the genetic predispostion to grow a large one is there, though.
As far as the color, an inch long fish is still developing color. Yup - he probably has taken on his first "adult" colors, but most fish of that size (other than calico) do not keep their "first color". Chocolate and blue are a common color seen in very young fish. As the fish ages, red will most likely be the predominant color.
Color, just like the wen, is mostly determined by genetics. There is not a great deal you can do to keep the chocolate color if the fish is programed to be a red. If you have a fish that does remain chocolate or black or any of the "more difficult" to keep colors, you can help keep those colors clean and bright by keeping the temperature of the water on the cooler side. Orandas do very well in 66-70F water. Cooler water can help prevent a black fish's (chocolate is a derivitive of black) belly from bronzing out. In a very small degree, the pH of the water also can play a part in the color. Higher pH is more friendly to the blacks than lower.
I suggest that you just watch and enjoy your little guy as he grows. The amazing kalidescope of colors on young fish never cease to amaze me.
Wow! This post has really been very informative and very helpful. ^^ Thank you so much.
I've already looked into my goldfish food (one of those wardley cheapo ones, but I don't have all my money right now) and it's got a pretty low protein around 35%. I've heard that plankton can be a real booster for protein, but it's not suggested often and it's bloody expensive! Still, I hear those Hikari products are really good to use, as are blood worms and tubifex worms. A lot of the posts around here have been incredibly helpful. Even so, is there anything else you suggest I should do for my baby oranda? I'm trying to find live plants that he would like to eat, but my petshop isn't very informative and I'm scared to put in anything that might make him sick. Your help would be VERY appreciated, as you guys seem to be the most reliable information I can get!
Oh, and I'm prepared to have myself a red oranda. I wish I could keep his chocolate color, though, and I'm making sure he stays on the cold side of the room. I hear sunlight also changes their color quite a bit, so he gets a little less light than the rest of them...which, honestly, he seems to like more since he's small and very skittish. I feel bad leaving him in such a big tank by himself, but I know my calico wouldn't appreciate being cramped and both my giant orange fantail and my shubby would try to kill him. So, aside from temp, sunlight, and avoiding color-changing foods, I guess its' really just a matter of time...*sighs* Oh, well. I'll take a ton of pictures of him now so I can show him later on in his life what he looked like when he was a baby. ^_^
