in UK I have found it is about right for albinos. Sometimes you might get lucky and find one for less.
If you are interested in genetics take a look at this site but on this page.
http://www.caudata.org/axolotl/genetics.htm. John C has put a lot of good information on here.
Basically 2 genes are required for the colour one is supplied by the male and the other by the female. However genes come in dominant and recessive versions. If an an animal has both dominant genes say for melanoid (M/M)(black condition) then it will be normal coloured. If it carries one dominant and one recessive (M/m) it will be normal coloured. However if it recieves two recessive genes (m/m)then their combined effect is to make the animal black. It's easy to plot the options in whats called a punnet square. Try a search on it you'll find loads of examples.
However, there are 4 basic sets of genes controlling colour of your axie. (Some work cumulatively others appear to overule others) So therefore a lot more possible combinations. So you can see it can be quite difficult to determine all the genes your parents would donate and you sometimes have to extrapolate them from breeding results. e.g a parent animal that was A/A or A/a would look exactly the same. If none of the hatchlings in a batch displayed the a/a result (albino) then you would be quite certain that both parents were A/A or one as A/A and the other A/a. That would be the best you could do in such a situation.
Ok thats a potted summary. Happy to answer any more questions but have a look at the page aboe.
