The whitish Gecko is a bred-in color variant. My sister has 3 leopard geckos..had them for 10 years so far.
We currently have...
My wife's herpetarium includes 6 Anoles
x2 Bahama Anoles (1M, 1F)
x4 Green Anoles( 2M, 2F)
My son has 3 other Herpetariums
1 tank with X1 Crotaphytus collaris (eastern collard lizard)
1 tank with x1 Crotaphytus Bicintores (Mojave desert collard lizard) and x2 Elgaria multicarinata
(southern alligator lizards)-- one is 15 inches

!
1 tank with x1 Eumeces skiltonianus(Western Skink) + 3 tree frogs(but they don't really count to mention since this is a reptile thread).
The collard lizards are known to live a long time as well...my son has kept one of the collard lizards plus the alligator lizards for 3+ years now.
