Nice big dark asperas,any idea where they originate in the wild,in the first pic,the 2 top left of pic look like a pr,male on top,female with more turnippy shaped tail,the bigger forms can be tricky to sex,both sexes can have huge fat tails of similar shape and boofy heads

I have a smaller form of aspera,females always have turnipy tails compared to straightish tails of males,plus with age males heads tank out,but can be subtle till they age a bit

I think its hard to tell, but my first look would be male.
What size and weight do they have?
As I told they look very much as mine, they are aboud 500 and 700 grams.
