So I just recently got a 20g L tank and wanted to get an axy. I got a HoB filter, a clip fan to keep water cool, and a clip light. We haven't gotten the axolotl yet, waiting for the tank to cycle. But I didn't get a lid. I didn't know how I would be able to use a clip fan, a clip light, and an hob filter with a lid. Any advice? I know a lot of people have had axolotls without a lid and had no issues.
