I just bought a Pair of Vampire Sword tails, and although I usually receive reliable info from the Aqua shop I usually do business with, I have this feeling I've been misinformed. It's my exp. that there are obvious differences between the sexes, have been breeding lives for a few years now, when I saw the vampires I couldn't resist getting a pair, the guy at the shop said I had a male and female , but my exp with swordtails left me doubtful, I've contacted the breeder, but for obvious reasons they were less than helpful, citing "this is a new breed and not a lot is known about them". OK my question is, do both Male and Females of the subgroup have the extreme display in fins and type, or are they the same as in the regular specie types the males have the display fins and the females are of regular fin shape? Any advice would be helpful. If I have to get a regular red velvet female to breed back to the male or males, I can get started, also the pair I have, show 0 interest in one another, even though all the conditions for the perfect breeding tank have been met. Thanks for any help!!!
