The Humu triggers can get quite big too! I have swam with them around 12" in length. Sometimes even as big as 15". Very pretty fish.
I had a pinktail showsize, black durgeon show size, clown trigger show size, picasso trigger show size, picasso trigger small, picasso trigger medium, blue line trigger medium, undulated trigger small, rectangular trigger medium, and a large huma all in my 150 with no problems. Then I changed around and I put my titan in my 150
