I made the mistake of getting a blue linkia.
Even after a 2 hour acclimation, perfect water conditions, no agression towards him, etc., he only lasted 2 or 3 days, at which point he started to "melt". He might have been in bad shape when I got him, but that experience has scared me away from thinking about getting any more linkia's.
