I have a school of Lyretail Anthias - 6 females and 1 male.
I have read up on the hierarchy system and noticed the controlled aggression the male uses to keep his females in line (and stop them from changing sex
)
What I am not understanding is the two smallest fish of the school are not allowed to swim with the others, they stay on separate sides of the tank and only join the school when in their area.
Also these fish are not growing like the rest, they are half the size of the others, yet all originally were the same size.
