Hey, i have had a male cacatoo ciclid for about 6 months now and recently added a female. Its in a 20 gallon long that is heavily planted. The male is non stop harassing the female but there is no damage done, yet, after a week. She is very young, just at selling size and he is about a year old, is it normal behavour for him to fist flare and wiggle and show of his colors then dart right at her as soon as he sees her. Is it just breeding behavour or pure agression, what should i do?
