That was a gamble that worked out for me. They are now however no longer together. The smaller one was not handling the winter very well so I passed it onto a mate.
I do not really want to re-introduce them again in case things are different this time.
That being said I can buy a leichardti basically any day of the year. You unfortunately cannot. So I guess what i'm trying to say is prepare yourself for the worst because the chances of it not working are definitely higher than it actually working.
Even at a young age they will fight with each other. LFS will not keep juvies together whereas you will see them keeping juvie silvers together.
