my L114 was pretty antisocial, he will leave other fish alone as long as they leave him alone. I had a dragon fin L091 in that tank and it start competing with the L114 after realized that it has became bigger since it grow faster. the L114 was 6.5'' and the L091 was 7.5'' when that happen and I found the L091 dead inside the L114's cave. No sign of aggression between them before that.
