:( That's so sad you had to put him down, I did that to Sapphire and it was such a sad thing to do....
I'm thinking about trying another pair, Glorfindel and Seras never worked, I tried 3 times to spawn them and each time Glorfindel was too aggressive. I'll probably use one of my LPS males, and all my HM females are really nice so they can hopefully counter any bad form the males have.
I could try to breed Seras with my platinum orange dragon, I should get HM's from this
I'm a little unsure if I would want to do marbles, the male is a super delta so I don't think I'll get any HM's from this spawn.
Or I could take a risk and go with my new boy and my blackfire female female, I think I'll get rose tails, feather tails, OHM, and HM since the male looks like he might become a OHM and already has excess branching, and the female is also OHM.
