I decided to move my betta from the community tank into is own little tank. I picked up a 1 gallon hex tank kit. It has an undergravel filter and I added a few live plants. My question is about lighting, how much does a betta need? Is the ambient room light enough? He will be sitting on my computer desk and its fairly bright. I've never kept a betta in a small container before and I am somewhat worried about about making him sick.
