I had a Six-Line wrasse in my current tank (trapped him out with an inverted coke bottle a few months back),
I waited a year before I added a Mandarin. The 6-line was in there a few months before. The wrasse unmercifully pecked that Mandarins head. The Mandarin did not last a week.
Im moving into a new tank yada yada yada...
Can wrasses and Mandarins live together in a 48 X 24 120 ?
If so, I should definitely add the Mandarin first, right?
PS (I`m setting up the plumbing today!
