I don't know what those are, but there are some microscopic mite-like bugs that a lot of the hatchling Brookesia (chameleons) and minature geckoes eat when even springtails can be too big.
On that note, I sometimes notice my dart frogs eagerly hunting and apparently tongue-flicking & consuming organisms in the moss that I can't see. Plenty of tiny food swarming about, apparently.
