I would mark this as location inaccurate rather than not wild. Although I think once you capture an animal and transport it away from its initial location, with no plan to return it, then it definitely counts as “captive”. So it’s either/or, at least one of those two.
On the other hand I understand that fish market observations have a lot of value, and that it’s usually impossible to determine what the actual location was… One of those instances where the current “casual” system is kind of misleading and unhelpful.
Or maybe these should be treated similarly to escaped pets where intuitively they should be made casual but we just use an annotation instead.
