I have four Vinegaroon tanks and every tank has a piece of cork bark, large piece of moss and reptil soil as substrate except one is coco fiber. One of the tanks has a small green plant looking thing starting to sprout. It just pushed thru the dirt in one day because I check every tank daily and it wasn’t showing yesterday. I do mist all the tanks at least once a week but I don’t leave it drenched in water. Humidity sits anywhere between 75-85. I’ve not had any issues with mold or fungus as of now. I tend to spot clean the tanks and provide clean water often. It would look pretty cool if a plant started to grow and add some life to the tank but should I be concerned and remove the plant or let it continue to grow and see what it becomes.
