Working temperature range
Keep Monocentropus balfouri around 20–25°C. Use that as a practical captive range and avoid prolonged exposure to temperatures well outside it.
Socotra Island Blue Baboons do not need the enclosure to hit one exact number all day. Normal small room fluctuations are easier to manage than repeated heating and cooling adjustments.
Measure the shelf, not just the room
Check the temperature where the Monocentropus balfouri enclosure actually sits. Shelves near windows, radiators, computers or external walls can differ from the centre of the room.
A thermometer placed near the enclosure gives more useful information for a Socotra Island Blue Baboon than a reading taken across the room.
Avoid direct heat on the enclosure
Do not attach a heat mat directly to a Monocentropus balfouri enclosure. Small containers can develop concentrated hot areas that are much warmer than the surrounding room.
If the room is genuinely too cold for Socotra Island Blue Baboons, warm the room instead and check the temperature at enclosure level. That gives a more even and controllable result.
Summer heat
During hot weather, keep Monocentropus balfouri out of direct sunlight and watch rooms that heat up during the afternoon. A closed window area can become much warmer than expected.
Do not respond to a warm day by soaking the Socotra Island Blue Baboon enclosure. Temperature and substrate moisture are separate husbandry issues.
Winter conditions
In winter, check the coldest part of the day where Monocentropus balfouri is kept. Rooms can cool overnight even when daytime readings look comfortable.
If room heating is used, remember that it may also dry Socotra Island Blue Baboons enclosures faster. Adjust watering to the actual drying rate rather than assuming winter always means wetter substrate.
Use behaviour as context
Temperature readings for Monocentropus balfouri should be considered alongside normal feeding, retreat use and moulting. One slightly different reading is less useful than a consistent pattern over time.
If a Socotra Island Blue Baboon suddenly changes behaviour, check temperature along with water, moisture and recent disturbance instead of assuming temperature is the only cause.
