Possibility grandchildren species:
• mourning geckos – Raeanne or Vivian are my most exciting guess. Raeanne is almost old enough.
(but this seems like the wrong texture for MG egg? I’ve only seen photos, however.
I believe they usually stick to something so doubt it would fall onto moss without damage?)
• Isopods – nah, but that would be fun.
(egg too big)
• Earthworm – the least exciting possibility.
I have two +? of them squiggling around the substrate. Earthworm? Do earthworms lay eggs? If they do, I doubt they would plop it atop the moss. I feel like earth worms would be more considerate.
• Spider – possible but unlikely
( I see no spiderlings. Did invite an elderly house spider to spend her retirement in the Viv. She only lived a couple days, the hatched egg appeared a week later – it’s possible she laid an egg but I would have seen at least one of the babies by now. Also. Egg is larger than spider – but I’m no spider egg excretion expert… so maybe. Bonus – do spiders have cloacas? Time to go down that rabbit hole I guess)
• Gertrude the snail – only one snail, not Gertie babies
• Carnivorous flat worms – yuck, not more carnivorous flat worms
• springtails – nope
What’s your guess?
Is it morning gecko? Oh, I hope it’s morning gecko!
If you’re correct I’ll name my firstborn after you. For your sake and mine, I hope it’s not more carnivorous flatworms.

I would assume it has to be the gecko, invertebrate eggs don’t look like that and aren’t that big. The biggest insect egg in the world is like half an inch and most are far smaller
Not a mourning gecko egg unfortunately but I have no clue what it is
Spiders make egg sacks, sometimes as big as them, containing many many eggs.
Look for “tarantula egg sack opening” and you’ll see plenty of videos of keepers and breeders opening them, with spiderling in various stages
Idk, this looks more like a plant gall or mushroom cap to me. I don’t think there are many eggs that would have thick, woody sidewalls like that. It could be a spider egg sac, though those are usually fairly webby and spongy.
Did this just appear randomly overnight or did you discover it while moving things around in the tank?
Might be a nest from a specific wasp. Some here in Europe do that I don’t know if it could be something like that in your case
none of those. doesnt look like a mourning gecko egg, unbelievably too big for an isopod egg, not an earthworm egg those are like small jello balls, looks like it could be a spider egg but not with that huge hole in the middle, so once again no. too big for snail eggs, and not round enough, depending on the flatworm you have, they either dont lay eggs, or they lay small cocoons that are muuuuch smaller than that and underground
