I moved my Betta, Skittles to a new filtered tank , he's been living in a bowl for about 2 months. the tank is hexagonal and has a light on top. here's my problem, the tank is fine, but when i turn the light on he then starts flaring and freaking out! should i just never have the light on or is this something that he'll get used to? i know he see's his reflection and i don't want him to stay stressed out! thank you!
