The eggs are a little over 1 mm in diameter. The terrarium is a wet forest biome with isopods, springtails, earthworms, julids, slugs and various assorted critters that hitched a ride when I collected Moss and earth in the forests here in middle Europe.
(And yes I’m working on reducing the amount of water in the false bottom.)
They look like slug eggs
Awww little sluggies! Thanks!
