This.
FH breeders/vendors aren't morons, a good breeder will sort out the potential rock stars at an inch or less, and keep going from there. There is no accident here. Agree 100% with Barrett, you got gotten. That SRD may not even be part of the pair from the fish that you received. I trust online FH vendors as far as I can throw them.
As far as diet, I raised all of mine over the years on NLS, exclusively. As others have stated, best to buy in bulk, not little packets.
Good luck with your new fish.
