I added in a 4.5" male jag in with my 5" Female. Immediately she started shaking her head back and forth so fast I thought she was having a seasure. She keeps picking up gravel with her mouth and spitting it out as well like shes trying to put on a show for him. She has also become more territorial chasing my bigger Festae around the tank since he has arrived 48 hours ago. Is this prespawning behavior? Shes been doing this nonstop for the past two days, is it ever going to stop? The two jags jave been inseperable since I dumpped him in there.
