@Morrison: I love that site! It's a little hard to tell the albinos and white ones apart, as some of them don't darken until later. There are apparently 5 types of 'light' coloured axxies on there; the axanthic albino, which can turn yellow with age but is not strictly golden, the melanoid albino, which has NO colour at all apart from very pink gills and sometimes faint iridophores, the Golden Albino (a lot like the other albinos, but ranging in colour from a pale yellow to a very dark, orangey gold, a lot like NeekaLovesYou mentioned in her post), the white albino, which can have shiny pigments or iridophores on its gills and skin, and leucistic, which can be differentiated from the others by its black eyes. This one is not technically albino because it has pigmentation in its eyes - as Morrison pointed out, there are 4 types of albino. They can also get 'freckles' or 'masks' which are also determined by genes. There are also the very rare Piebald and Harlequin types. Piebalds tend to be a pale colour marked all over by a dark colour (not just freckles or a mask like leucistics get), and Harlequins are pale with orange and black markings. The only known example I have ever seen is here:

At a guess, your bottom one is either Melanoid, Axanthic or White Albino, depending on whether they have iridophores or turn slightly yellow as they age. Your top one looks most likely to be a Golden Albino. They already have very pronounced colour and will probably be very vibrant when they mature!
It's also hard to tell Melanoids and Wildtypes apart. Toothless was sold as 'black,' and she was for about a week, then her olive green patches and shiny 'spots' came through!
Either way, your axxies are still gorgeous looking babies!
