So previously I had 50/50 lights because didn't know they were for reef. I bought ultra sun 6500k 10w bulbs yesterday and replaced all my aquarium lights. All of my other bettas are quite happy with the new lights and actually have been more active. obviously my plants are happier too. My female however has taken to hiding and won't come out. Any time I come to the tank to look at her and put my finger to the tank she freaks out. Partially clamped fins, stress stripes, swims like a maniac. She has never done this before. She was my most personal betta. I don't understand what happened. She comes out to eat and then darts back to hiding. She won't even show off for Galileo.
She is in a 5.5, the temp is 80, she is the only inhabitant but her tank is next to one of my males Galileo and usually she loves to show off for him. Parameters are perfect 0 amm, 0 nitrites, 5 nitrates.
