I recently ordered two new heaters for Sprout and Makoto my newest bettas. I was using a heating pad before as I didn't have any extra heaters on hand. Since I've put their heaters in they're acting as though their blind. They can't see their food, or see me when I go up to the tank or take the tops off to feed. It's really worrying me. Makoto is usually very active and acts all big and tough but lately he's just sitting at the bottom with his fins held together. I can't see how or why these heaters would be causing them to go blind, but it's odd that both of them suddenly can't see after putting them in. Any ideas? I'm really worried about my boys :/
