my octopus seems like it wants to come out during the day but the light is to bright so it waits untill the second the light is turned off. i recently tried removing the 10,000k daylight and keeping my actinic in and he seems to like it better. i just got done reading a tread and it said that actinic is to bright. I'm not worried about the brightness because my octo seems to like it better, i want to know any other suggestions because i do not like the look of a blue/purple tank...i have a 4' double bulb fixture that uses t5 bulbs. if anyone has any idea of a bulb a should try please feel free to post. thanks!
