So I just received two female adult geckos! I am so excited but have a few questions first! Here is my set up: 20 gallon tank, two caves, one empty on heated side, other on cool side with moss. I have a water dish and a plant. I plan on feeding them 3-4 crickets a day dipped in reptile calcium. I am using a basic heating pad under the tank with the cave with nothing in it. The substrate is a soft tile I got from menerads. I have a question about the lamp though. I put a lamp on the heating side with 75 watt bulb and noticed the temp almost went up to 100! So I immediately took that out and switched the bulb to a 13 watt. Is a lamp neccassry? Will a heating pad under the tank do just fine? It feels warm, but not extremely hot. I ordered a reptile temp gun so I cant tell you what the temp of the heated side is yet. Also it is safe to keep the 13 watt bulb on during the day? Anything im missing or advice would be appreciated! Any important details you think I need to know would help too! Thank you guys!
