11 months is old enough. A Nova is an enigma RAPTOR (as I'm sure you know and I just found out from looking it up since I can't keep track of all the new morphs). That means you have the following traits to play with: enigma (dominant), stripe (possibly polygenetic), eclipse (recessive), Tremper albino (recessive), tangerine color (polygenetic). You need to figure out which of these traits you want to produce and whether you want to add in other traits (e.g. Mack Snow). Then you need to buy a female that will do that for you in 1-2 generations.
It's much better if you figure this out yourself instead of just going ahead with what someone tells you, in my opinion.
