now that i recall my first brigg babies were all golden, with the mom being ivory and the dad being golden (my only adult snails at the time - 2008). after that, i picked up a male that must've had blue genes but had a very green shell and a black foot. kept one of the largest females from the first batch of goldens and those four (ivory female, golden female, golden male, blue gene green male) were my foundation for the following 7 or so generations. so yes, genes do play a part, because i'd never introduced jade snails and ended up with jade babies.
i'm bored, so dug up a few old photos of my original adult snails (minus the goldens - can't find photos of them), one of the jades i raised, along with a shot of the babies i had at one point.
this is the ivory not too long after i got her in 2008
this is one of the jade babies i raised up, photo taken some time in spring of 2009. her shell is a fair bit darker than most jades i've seen/had.
this is the blue/green male
and this is what the original ivory female looked like in early spring of 2009 - odd that there is blue showing in her whorls. and she colour changed on the top of her shell to a bright magenta! my theory is diet had a part to play - i feed a lot of frozen bloodworms. she lived about 2 years (spring of 2008 until spring of 2010).
a handful of my babies!
