Tetramorium proximum

Quick Summary

• Difficulty: Medium
• Origin & Habitat: Madagascar, found in rainforests and montane rainforests at elevations from 25 to 1680 m, including isolated humid forests in the west (Analavelona, Isalo, Ambohijanahary) ^[1].
• Colony Type: Unknown, no specific data on queen number. Typical Tetramorium species are monogyne (single queen), but this has not been confirmed for T. proximum.
• Size & Growth:
  • Queen: Not documented ^[1]
  • Worker: Not documented (head width 0.65-0.81 mm ^[1])
  • Colony: Not documented
  • Growth: Unknown
  • Development: Not documented (All development timing is unconfirmed for this species.)
• Antkeeping:
  • Temperature: Tropical species, keep warm year‑round, ideally 22-26°C. Avoid prolonged drops below 20°C ^[1]. Provide a temperature gradient in the nest.
  • Humidity: High humidity required, keep the nest substrate consistently moist but not waterlogged. Misting and a water reservoir are recommended ^[1].
  • Diapause: No, as a tropical species from Madagascar, it does not need hibernation. Maintain warm conditions throughout the year ^[1].
  • Nesting: Naturalistic setups with moist substrate (soil/leaf litter mix) or a test‑tube with a cotton reservoir work well. They live in leaf litter and rotting wood in the wild. Y‑tong or plaster nests also provide good humidity control.
• Behavior: Workers actively forage on the forest floor in leaf litter. They are not particularly aggressive but will defend the nest. Due to their small size, escape risk is high, use Fluon or other barriers. They are ground‑nesting and do not climb extensively.
• Common Issues: mold growth requiring careful balance of ventilation and moisture, use a gradient to avoid stagnation., colony stagnation if temperatures drop too low, keep warm and stable., escape risk from small gaps, seal all openings thoroughly., humidity stress if substrate dries out, monitor moisture regularly., limited growth information, patience needed as development rates are unknown.

Housing and Nest Setup

T. proximum lives in rainforest leaf litter and rotting wood ^[1], so a naturalistic setup with a moist soil substrate works well. For the founding stage, a test tube with a water reservoir and cotton plug is ideal. As the colony grows, you can transfer them to a Y‑tong or plaster nest with narrow chambers that hold humidity well. Always provide a moisture gradient: keep one part of the nest moist and another drier. Cover the nest to keep it dark and secure. Escape prevention is critical, use Fluon on all openings and seal any small gaps.

Feeding and Diet

Generalist feeders, offer small protein sources (fruit flies, pinhead crickets, or tiny pieces of insect) twice a week, plus a constant sugar source like honey water or sugar water. Remove uneaten prey after 24-48 hours to prevent mold. Once the colony has more than 10 workers, maintain a steady supply of sugar water to support brood production.

Temperature and Seasonal Care

As a tropical species, T. proximum needs warm conditions year‑round. Keep the nest area at 22-26°C ^[1]. A heating cable on one side creates a temperature gradient. Do not cool them for hibernation, they are active all year. Avoid drafts and sudden temperature swings.

Colony Development and Growth

Specific colony development data for T. proximum is not published. Based on typical Tetramorium biology, the queen likely starts a colony alone and the first workers appear within a couple of months under good conditions. Growth rate is unconfirmed, but expect a moderate pace as the colony grows. Be patient during the vulnerable founding stage.

Handling and Observation

Workers are not aggressive and are easy to watch while foraging. Their small size means they can slip through tiny gaps, always use barriers. When the colony is small, avoid excessive disturbance. Once established, you can observe feeding without causing stress. They are most active in the evening.
