And there are some relatively harmless, and simple, behaviour "experiments" which can be done with them; fry following the red dot on a stick, adults contesting territory with red dot on a stick, male attracted to purple dot more than red dot, etc. ------------------------------------------------------------------------- This is the apistogramma mailing list, apisto@listbox.com.
