hiya great fish dont be worried about the missing verntral fins if you ever did want to breed her she would not pass this on to the fry, its where as fry they have spent most there time at the bottom of the tank. its very true about DT having bent spines i did have a spawn of them but they were all very badly bent to i culled them as it would be so hard to find them home as much i would love to have kepted them myself there was just to many.
i think also the males tail damage is due to shipping and hopefuly it will clear up and heal fine.
