How long to attach?

[SaltyDr]

Just got a few Florida ricordia and as using netting to get them to attach. How long does it take? I am guessing about 2 weeks. Unfortunately they moved some since I put them in the tank 6 days ago, but I am afraid to take them out again and set things back a week. The 5 rics were $45 total, so I think I got a good deal.

Sorry for the small picture, I had the setting wrong, but you get the idea.
