How visible is this species?
Mexican Black Velvets are terrestrial. Young Mexican Black Velvets may dig more, while some adult Tliltocatl schroederi become more visible once settled, although individuals still vary.
Do not judge the welfare of Tliltocatl schroederi by how often the spider is on display. A secure retreat is part of good husbandry even if it means seeing the animal less often.
Life stage
With Tliltocatl schroederi, young Mexican Black Velvets and recently rehoused spiders often hide more than settled adults. Premoult can also keep a Mexican Black Velvet out of sight for an extended period.
With Tliltocatl schroederi, a sudden change in visibility is more useful than a simple count of how many hours the spider spends outside its retreat.
Enclosure design
Give Tliltocatl schroederi a retreat that suits its terrestrial lifestyle and position routine care items so you do not have to disturb that retreat for every water change or feeding.
A display enclosure for Mexican Black Velvets can still look attractive, but with Tliltocatl schroederi, husbandry comes first. A spider that feels secure is often easier to observe over the long term.
Do not disturb a hidden spider
Do not dig out or uncover a Mexican Black Velvet simply to make it visible. With Tliltocatl schroederi, hiding can be linked to normal retreat use, premoult or recent disturbance.
For Tliltocatl schroederi, leave established burrows and webbed retreats intact unless there is a genuine enclosure problem that requires intervention.
When a change matters
If a normally visible Mexican Black Velvet suddenly disappears, check water, temperature, recent disturbance and premoult signs before changing the Tliltocatl schroederi enclosure.
If Tliltocatl schroederi is otherwise well and the enclosure is sound, give the spider time. Visibility by itself is a poor measure of health.
