Advertisement I just rehoused these little guys this past weekend due to an outbreak of fruit fly maggots in their enclosures and in 3 days i've got mold which was not an issue i was having previously. The substrate is just coco fiber, the plant is plastic and the moss is part of what came in one of Jamie's Sling starter kits (i'm not blaming her supplies for anything just give a full description) sprinkled on top. I'm pretty sure the mold shouldn't affect the Ts but should i rehouse them again? I don't want to over stress these little guys but i don't want them to fall ill either. As you can see from the pictures there should be adequate ventilation and air flow so i don't believe that is the issue. The only difference i can think of is these were moved to a new location after rehousing (partially due to the Fruit Flys) and were sitting on my dresser under my tv which is brand new and puts out little to no heat to where they sit (i checked as i was concerned about this myself and didn't want to cook them). The substrate is moist as they are slings but i wouldn't say it's sopping wet by any means.
