I had my pair for 5 years before they spawned. (Of course, lucky for me, I wasn't trying to get them to spawn and one day I just got lucky!). After I'd had them about a year, they adopted a bunch of 'hairy' mushrooms, but it wasn't until four years later, when I put some more hairy 'shrooms in the tank that they laid their first batch - still within the original site, but I'm sure the coral addition was what prompted it. Since they don't have the option of swimming from site to site until they find what they want, it seems like it could be tricky to get them to go for a compromise. Mine took a full year to adopt the 'shrooms. I think their behavior with the anemone is a good sign. It might just take a little while longer.
