I may not succeed, but I don't see any real problem giving the single-sex option a try. I think my boys will love them. I may be surprised, but I have seen carp survive in much harsher consitions than this pond would seem to pose. I think I will grow them out in my RAC until they can be sexed. Then, all of one sex will go to the trout pond. Honestly, I'm much more confident about the koi than the trout.
