here is a pink one under 1/2 inch..no pics of a black one currently they are all mostly fed as wigglers...A friend of mine has a black female from me..Ill have to see if i can get any pics.
A new male that I am breeding with the female above. They both turned out to be homozygous recessive for the 'pink' gene!
I have about a dozen survivors from their last spawn (in a community tank), 4 of which are pink.
