How well would a 4" Undulated trigger mix with a 12" fimbriated moray in a 90? I currently have the eel with a 5" Humu Humu. Im not planning on having both triggers.
Would probably be ok since the eel shouldn't protrude into the triggers territory much, but undulated triggers are unpredictable as we all know... I guess it just depends on how much of a risk you are willilng to take.
