I know they market them for how they look under black light, but I use my normal lights. They're colorful and lovely still. I read black light ruins their eyes, plus since my tank is heavily planted, I need my usual lights.
I had no idea there were glo fish bettas.
I have 5 with a couple catfish in my heavily planted tank.
I have a lighted bubbler strip that makes it seem like a fish race. Might be tacky, but I don't care. (Yes, I have neon and black gravel to boot. )
My kiddo (3 yo) likes to point and tell me the colors. It's pretty cute, I assure...
