A pond favorite reimagined on the substrate. Koi isopods (Porcellio scaber) blend red, white, and black across their plates in a pattern that echoes classic koi fish, giving this rock-solid species a genuinely eye-catching look. Scaber originates in Europe and now thrives in temperate climates worldwide.
This species handles a wide humidity range and stays active whether your substrate runs a little damp or a little dry. They work through leftover food and decaying plant matter reliably and benefit from a calcium source to support healthy molts.
- Red, white, and black koi pattern
