I got a coralife colormax bulb. It promotes plant growth because I have live plants and uses a blue hue so no frog roasting I want to pair it with a night bulb to give him more comfort. I've read reviews on the bulb saying it has a pink hue, but I don't see it. I've found one that said it did, but there was a blue bulb option. It's $10 at petsmart.
