I'm new here but sorry I can't properly introduce myself right now since I have an emergency. My betta fish that I had for a year and 2 months is suddenly darting back and forth. I have him in a 2 gallon bowl, and feed him hikari bio-gold pellets twice a day 2 at a time. I change his water twice a week, one full and one half. His bowl is heated but not filtered.
I thought at first it might be from amonia, but I don't have those testing strips, and my small town doesn't sell them so I can't get them right now. I did about a 40% water change just now, and I used Prime water conditioner. He's still darting around. He seems to only do this when I come close and look at him. Otherwise he sits at the top of the water in his favorite corner like usual. He usually flares and swims slowly around with his fins poofed up when he sees me, but he usually doesn't dart around and seem like spasming like he is now. He seems extremely aggressive, his fins are all poofed out and he flares. Could someone tell me what could be wrong? Thanks.
