Actually my aquarium is not near a window and I keep my curtains closed all the time. for some reason my camera makes pictures brighter then they are. However, my light for this tan kind of does suck alot. I am getting a new one for coral and not sure when to use the blue light. I do have a hermit already and he is doing a great job with the sand, but he seems to be over whelmed with the amount of food right now lol. this week though I am getting some snails and was wondering which ones to get, so thank you for letting me know what to get
