I read this today:
Also keep in mind your color selection. I've found that in unrelated female community tanks, if you have a red female, nine times out of ten she will be your Alpha. Reds are just more radiantly aggressive than other colors. Except in rare instances, opaque or light-colored females will be lower on the totem pole (this does not apply to cambodian red females, who can be just as aggressive as solid reds). Of course, like all rules there are exceptions, and one should by no means take this as gospel law -- just as a guideline.
While she is clear it's not a fact. I three reddish fish or they may be reddish-orange. Plus cambodians. What do you think about this?
