| Every betta has their own unique personality, believe it or not. My betta flares at everything that comes near his tank - including me. As long as Alex looks healthy (dorsal fins not clamped, no velvety film on body or white bumps, etc.) and displays vibrant colors, he should be fine. As long as his appetite is good, he is healthy. Is his water heated? Bettas are tropical fish and thrive in warm water. I add 1 teaspoon of aquarium salt to my betta's 2-1/2 gallon aquarium. Sounds like Alex is just being, well, Alex.
