The spider beetles: tiny, globular, long-legged scavengers that look convincingly like miniature spiders and live like pantry archaeologists, working through dry organic debris in slow motion.
Keeping is a culture, not a display: a small sealed container, dry substrate with grain and detritus, and near-total neglect. Colonies tick along for years. The animals are harmless, flightless in the kept species, and fascinating mainly at magnification.
The market is a curiosity trade at curiosity scale: occasional listings, minimal prices, and a buyer pool of invertebrate completists and the microscopy-inclined. Established cultures produce surplus indefinitely, which caps the price at approximately the cost of the container. The genus sells strangeness by the gram, honestly.
The line on each tile: lowest ask per day.
Rarity BETA Rarity is supply, and only supply: the tier is how many sellers have ever carried a species, and for a single seller, how many separate listings. Price is not part of it, and neither is how recently it appeared. Tiers are given to tarantula species only.
