Mystery Wrasse can be on the aggressive side and unless you have a very big tanks it's probably not a good idea to try and keep more than 1. Also they're very expensive, so it's a big risk money wise too.
But I guess, worst case, if they don't get along, I could sell one, right?
Wrong :tongue1:
Worst case #1 - One wrasse kills the other wrasse
Worst case #2 - One wrasse harasses the other wrasse to the point you want to sell one of them, but you can't catch either in your reef.
Also one may chase the other causing it to jump out of the tank and do some carpet surfing.
Is a 4 line wrasse the same as a 12 line wrasse? Pseudocheilinus tetrataenia
