I don't know if this is true.... Maybe.... I truly don't know .... My inclination is that different fish have different triggers.Isn't it true that in every tank (almost) there is a "King of the hill" ..? and its best to let fishes that can't hurt too much be the king ... and not a Zebrasoma or HT or triggers that can gore other fishes?
I have found that when I remove one bad guy another becomes bad ..
When I removed my 6 line, no other fish become a replacement d***. When I removed my tail spot, my clown didn't go after my new goby, etc. Just not sure what the pattern is.
