Ok, I have a 10 gallon tank...have a Pleco, 2 s. tetras, 2 lemons and just added the second of 2 glofish to complete my tank. I have had the female glo for a month now...just added a male. Since I added him, he has incessantly chased and nipped at her! Should I get rid of him? Is he going to continue to irritate her or will it ease up after a day or two...
