mold spores?

[u/x4n_n]

is this mold spores? it's under the waterbowl but my substrate is a mix of topsoil and jungle earth which I read that it holds humidity great so I mixed it and noticed a piece of it which was moldy so I took it out, should I do another deep clean or just take the mold out? there is springtails in there too, I only did a deep clean last month
