If it's not damsels that people hate and try to get out of their tank it's 6 line wrasses.

I have 2 blue/yellow damsels in a 90. One gets 1/2 the tank, the other gets the other side. Works out well. You NEVER see them cross paths :)

I did love my 6 line wrasse, so much character... But he commited suicide by going down my overflow, and found him head first in my skimmer pump. That was a couple years back, and was a sad day.

Just to put it out there. I accept Damsels at no cost, you fish them out, ill take them. They go into my tank, and their fate is already sealed. Haha, let Darwin do the talking ;)
