Okay, so I posted a thread before about how my male won't build a nest. well, I put my female freely in the tank with him hoping he'd get some inspiration to build his nest. Now they're both acting even more strange! Neither of them are being aggressive other than my male flaring. He'll flare at her and follow her at a casual pace. neither are swimming fast and sometimes she'll follow him. They've been in the tank for about 20 minutes now and I was honestly expecting them to be more aggressive. Neither are making any attempt to hurt the other. And he's still not building his nest! Well, as I am typing this he made one attempt to nip at her; but he missed thankfully. They started swimming a little more quickly chasing each other a bit and now they've both stopped and are being still/ casually swimming again. I'm not really sure what this means? He's still acting weird. Flaring at her and swimming away, then if she doesn't follow him he turns around and follows her. Should I take her out? Is he flirting? Will this help him build a nest?
