The 'white' ones are actually blazing blizzards. They range between £50-150 in price. Most blizzards are brownish in colour. There's banana blizzards too which are a yellowy colour. Look on www.leopardgecko.co.uk for description and pictures of morphs.
There are black and white geckos called mack snows but the're still a relatively new morph and cost around £200-400!
you can also get the mack snows too but they are expensive and tend to be white with black spots or the odd stripe.i think they are gorge so after christmas im gona invest in a couple of females an a male see if i can get some little ones of them.
Bad-tempered? :shock: Really? My bb is the most gently laid back girl I have! I've never heard that before, although when we looked after our mate's geckos, he has one and it waved it's tail when we opened the viv for feeding. Didn't bite or anything, but was a tad grumpy some nights. :lol:
Just a general thing. Of all the leos that i've had through the shop the only time i've ever been bitten or heard one screech (they do) it has been Blazing Blizzards. They ar'nt all like that just never had any other colour morph do it.
