If the walls of the aquarium are totally covered in condensation, the humidity is too high for cased cakes (it's great for uncased cakes) and you may see bacterial blotch on the fruit. This causes slimy black lesions and pits on the fruit. If the humidity is not corrected, the fruit will be wiped out. Some of these bacteria are harmful to humans, so be careful to wash well after removing contaminated fruit. Lowering the humidity will almost always clear up the problem and allow proper growth to resume.

Anyone got more info on any of the issues in my post. Especially on trying extraction or black bacteria/spores?
