Same here - I received a long finned VT female and there wasn't a bite on her pretty purple/red fins <3
Well personally I would rather sell culls then kill them. Unless they were going to always be sick, in pain, dying, etc :) So I applaud any breeder who sells culls, who are not their best - I would keep my best to breed, the rest sold.
Breed for the breed, not for the money; the words any REAL breeder would understand.
You must know nothing in order to know all, for all is nothing and nothing is for all.
