Key benefits Observe ants closely without disturbing them: a transparent visor gives a clear view of daily activity while keeping the colony secure. Realistic living conditions: the living area is made of plaster to simulate a natural nest environment. Low-maintenance hydration: an internal water tank (approx. 20 ml) supports the colony for about three weeks between refills. Flexible setup and growth: three expansion ports let you connect additional modules or close them with included plugs. Product specifications Overall size: 3.5 x 2.7 x 4.3 in (90 x 70 x 110 mm) Activity area: 3.5 x 2.7 x 2.1 in Living area (plaster): 3.5 x 2.7 x 2.2 in Water tank capacity: approx. 20 ml (water fill opening on the right side of the living area) Expansion ports: three (front, left, right). Includes plugs for sealing unused ports. Compatible with standard rubber hose for expansion. How it solves common problems Visibility without disturbance: the transparent visor makes monitoring behavior, feeding, and colony changes easy without opening the nest. Stable micro-environment: the plaster living area closely mimics natural conditions to support ant activity and nesting behavior. Reduced maintenance time: a 20 ml tank minimizes how often you must refill water—approximately every three weeks under normal use. Scalable system: expansion ports allow you to connect further nests or tubing as the colony grows, or to keep it sealed when not expanding. Important usage notes Fill water via the opening on the right side of the living area. Do not overfill to avoid overflow. Use the included plugs to close expansion ports when not in use. To expand, attach a rubber hose to any port (hose not included). Ideal use scenarios 1. Classroom demonstrations and science projects: compact, visible, and durable for student observation of ant behavior and colony structure. 2. Beginner and hobby ant keepers: a ready-to-use starter nest with realistic plaster chambers and low-frequency water maintenance. 3. Research and observation at home or office: discreet, table-top friendly size for ongoing behavioral studies or casual watching. Why choose this nest Compact and complete: precise dimensions and a built-in water tank make this a practical, all-in-one habitat for small colonies. Designed for observation and growth: transparent viewing, plaster living area, and expansion ports support both study and colony development. Practical accessories included: expansion plugs are supplied so you can use the nest immediately and expand later if needed.
