Of course being hatchlings, they will quickly loose that colouration and will look altogeather different as they get older.
I personally am not in favour of mixing the species or sub-species, but I am sure there will always be people there to do it, and as long as they are sold as crosses then, each to there own.
What gets me, is when people try to sell off there offspring as a pure, when it clearly isn't, alot of newbies can get caught out by this, and that is very wrong.
