I am a long way away from knowing everything,, cheeky monkey.
Sandfire bearded dragons originate from the sandfire dragon ranch in the USA.
They do specialise in beardies with red and orange colours but the name comes from the place more so than the colour i believe and people have kinda adopted the name to go with redish orange beardies.
Hypo's you can say is a morph and can have come from anywhere, where as you cant have a sandfire thats not got at least parents or some part of its family tree coming from the ranch.
Remember you will not be able to see all genetic problems on the outside.
Being a breeder myself, i have been in you position before, the citrus is an incredible colour as are some of the reds and snows, so i did my research before spending that sort of money.
I have read the board many times over and have heard first hand stories from people who have bought them,, too many occasions for this to be worth my while even if they were free.....
If you want USA imports, go for Dragons den, If you want high yellows search out some hypo yellows,,
You can find what you are after without taking that risk if you ask me from very respected breeders for much less money, seems a no brainer to me.
and mixed opinions,, dont really agree with that, some may seem healthy in the flesh,, but they will still be the same as all the others inside.
some live, some dont,, but what goes on goes on and its more a case of some know what goes on and others dont rather than mixed opinions.
sorry for ranting and not aimed at anyone other than the cause which is none of you, But i cannot express how mad it makes me that people mess about with genetics so much in this way to produce such nice colours admittedly but at the same time such weak bloodlines as so much inbreeding has been done, just to make a few quid. and when issues crop up,, the aftercare seems shocking from a so called rescpected breeder, lol
That is a business rather than a passion and when you are talking about live animals, Its not on.
