my new aquired clownknife stays in a water sprite batch alllllll day long...hes new to my tank so i hope he'll get accustomed and come out soon, he better! hes damn beautiful!
yes they do take some time, i have had one for over 2 months and he is not that shy, comes out during the day at feeding time and occationally just cruising around.
Then i got 2 new ones a few days ago and they dont move until after dark.
i have 2 cks's you just have to wait a couple months before they come out. my big ck is the least shyish in my tank! always in the front of the tank and up by me.
