I bought an orange linkia before my tank was really established because I wanted one. He came from Florida to Ca. I acclimated her for two hours and then placed her in the tank. She did really well during acclimation. Moving all over the place. After I put her in the tank, a while later, she got in a position where her leg looked stuck. I picked it off the glass gently and held it in the water. It looked all closed up so I thought it was dead. I pulled it out of the water and was ready to put it in a baggy to send back when I saw the little tenticles coming out. I freaked out and put it right back in. God I thought it was dead!!!!
After that, it moved all over the place. There are times that it gets in a position and stays there and looks like it is shriveled. I pick it up, Gently again mind you because I am a little nervous and I put it on a rock and it moves all over the place. I guess I am really lucky!!!
I know how hard it is to lose fish and animals. She is my favorite and losing her would be hard.
Don't blame yourself too much. It is hard to know what is best at the time. I think you did the best with the knowledge you had. There will be a day when you will keep one. I have had mine now for a week and it moves and eats actively. No shriveling noted. They can make it!!!!
Keep trying!!!
