I went away and I came back to find my six line wrasse missing in action. I cnat find anything.  Everything else in the tank is fine, so either hes playing one big game of hide and go seek or hes dead and the carcass is gone.  I did a water cha nge, havent seen anything, is it possible hes still alve, like, do wrasses hide for that long/ do they do that?  Also, if i use a Tap Water FIlter by AP, will it impact the cyano in my tank? Thnx!
