just a quick question. Would a 6 line wrasse eat ceriths??? I am considering one for my 20 g nano. I have 6 ceriths in with 27 lbs live rock, 26 lbs of crushed aragonite sand, CSS 65g skimmer, whisper 20/40 trickle filter, 50 w heater and 15 W VHO 50/50 bulb. Any suggestions and advice would be much appreciated.
