I just recently bought a RES and I'm worried that It might not be getting enough light. He's in a 20 gallon tank right now and is a few centimeters short of a inch. I'm wondering if he needs a UV light at this stage or not because I went to pet smart and the pet care expert told me that I don't need one for him since he is so little. I asked him what about 2 inches and he said even then that he's to small.
And well I'm here for a second opinion hoping that one of you can help me so I can give Gordon Freeman a healthy long life.
