O.K., my nightly Platy emergency question. Thanks for your patience!

God knows, I don't want to euthanize him and am doing everything you're telling me to keep him going. But, I did wonder something tonight that I thought worth asking.

If he survives despite a curved spine, assuming that's all that's wrong, what happens when I put him back in the community tank one day. He's the only male Platy I have. So, if he mates with the females, am I risking passing on a deformity in the fry?
