lol my first pair befor i bought a yellow head wrasse lived 9 months my new pair have been in the tank almost a month. the trick is you dont want to over clean your water i do not use a uv or any polisher filters but if you want featherdusters and fine filter users you cant keep the tank imaculate . they need junk swirling all the time. heck even 20 yrs ago they were the easiest thing to keep alive but the reefs of today are too clean for them to last long.just my experience and openion.
