Han - thanks for the reply! I am in good shape then because I am currently lighting the tank with two t-5 bulbs - one full spectrum the other blue(the lamp is for a salt tank) and then a 3rd bulb which is a regular t-8 fixture with a regular plant grow bulb. I do not have a basking lamp and the water portion of the tank is not heated. Will that be enough to keep them thriving, in good condition and color?

Here is a pic of my tank
