acro eating FW. I'm not 100 percent, but the ones I had were very small, almost like redbugs (a period on your screen). The bigger brown red ones like 1-mm in size may be the safer ones.
If you have AEFW, you can notice because acros will have little pale 'bite marks' on the skin, and will suffer from the infestation.
seriously, though-after looking around it may be red bugs?? I can't get a pic. right now, but where would I find a pic. of red FW as apposed to red bugs? and will the wrasse take care of the bugs too?
I agree that introduction of livestock is not always the answer to correcting an infestation but I can tell you for sure that adding chemicals designed to kill inverts often ends in tragedy. It seems this hobby leans more and more towards natural ways of doing everything. It is always my approach to target issues in the reef as they might be dealt with in the wild. Natural predators do not always work out the way you hope.
