Tetra Whisper H10 Is It Ok For Betta - I had gotten the 10 gal kit from walmart and is cycling for 3 weeks now. Has a heater with preset and keeps it at 79F. During that time i had researched fish that will be happy in the set up. I had decided the Betta. The concern is the current. I had done the bottel trick. Is it ok for betta?
