The trouble is: Breeders, if they want good results cost-efficiently, have lots of females. Single gene or multi gene females, maybe even normals. But each male is bred to several females, so for breeding, they want true powerhouse males with lots of genes.

So, being a single-gene spider male, its unfortunately not interesting for breeders, it is a fancy pet.

175 sounds fair, i think maybe you can get it sold for 200-250, but thats the upper limit. It is a very nice pet, but since it only has one gene and its a frequent and easily available gene, its not for breeding.
