My Orange Linckia is 6 1/2 months old. My tank is 6 1/2 months old. Put him in right after my tank cycled.
Slow dripped him for 4 hours.
Every now and then my wife brings home live muscles from the market and I crack one open and put it in my tank.
Within 30 minutes, sometimes sooner, the Lickia is right on top of it and sits on top of it for a good 24 hours before moving off of it.
I know they say linckias only eat film algae but apparently mine loves muscles!
