Hello! I am planning to buy a baby beardie in the next week or so, however I still definitely have many questions regarding lighting in particular. My tank is about 55 x 20 x 20". I was planning on buying a mercury vapor bulb as well as a CHE for nighttime just in case because my tank is near a window. what wattage would make the most sense for a tank that size? Whats the best MVB in your opinion? what fixture should i buy for each type of the lights as well? I also bought a termostat, so which bulb should i plug into the termostat? Can a new MVB sometimes damage a beardie (I heard someone once say that it can damage them if the uvb is too strong). I can post photos of the tank as well (its a little barren but im planning on adding a lot more stuff). My main question is if its safe to use a rock/boulder from the beach I found as long as a soak it? Im having a hard time finding actually good basking items/accessories on amazon under 20$ :/. Links to products would be greatly appreciated for any of the stuff i listed. PLEASE respond asap since im trying to buy this stuff before I go the the reptile expo on Saturday
