What is the best non basking bulb to simulate daytime that will not harm my pacman frogs? I use mostly my room lighting for one of them but the other 20gal tank is set up in a dark area and I would like to have some lighting. I've read of people using regular CFL bulbs from home depot, if that's a good idea what kelvin ratio would be best? Any input would be much appreciated as I am a new member and semi new owner.
