Hello. I have a colony of ants Atta sexdens past month, the fungus is gray-white but is not growing, it is 10cm square and is in an aquarium 50 * 30 * 30 cm heated by two hot plates, the fungus is on Ball clay moist and humidity is 95%. I wonder why my fungus does not grow.
You should take a look at other blogs of Atta sexdens. Many people give the a seperate plastic box or something where they can put their fungus into. In the small room they can manage the conditions by themself
