The whole setup had to be replaced. That is the exact problem this formicarium solves. The two standardized expansion ports let you clip on additional chambers as the colony grows, without disturbing the existing tunnels or stressing the workers.\u003c\/p\u003e\n\u003cp\u003eThe nesting core is cast concrete, which is the right call for humidity retention. Concrete breathes slowly, holding moisture in the 50-70% range that most temperate species need, far better than plain acrylic alone. The outer observation walls are clear acrylic, so you can watch foraging behavior, brood sorting, and queen activity without opening anything. A shading board slides over the nest side when the ants need darkness to feel secure, and you pull it back when you want to observe. Simple, and it actually works.\u003c\/p\u003e\n\u003cp\u003eThe larger configurations (Leaf AB, Space B, Ocean B) add a dedicated moisturizing zone and a separate food feeding area, which keeps the nest core dry and the foraging zone active. That separation matters more than most beginners realize. Wet food near the nest invites mold, and mold kills colonies faster than almost anything else.\u003c\/p\u003e\u003c\/section\u003e\u003ch2 class=\"yvk-prod-h2\"\u003eWhy this modular ant farm
