Powder Blue Isopods | Free Shipping | 10 counts

Porcellionides pruinosus “Powder Blue” is one of the most recognizable and dependable isopods in the hobby, valued for both its bold appearance and reliable performance in bioactive setups.

Named for their striking black-and-white pattern, Dairy Cows stand out immediately—no rarity gimmicks, just a classic look that holds up over time.

Unlike delicate Cubaris species, Dairy Cows are fast-growing, hardy, and highly adaptable. They tolerate a wider range of conditions, reproduce quickly, and actively consume waste, mold, and decaying matter—making them ideal for beginners and experienced keepers alike.

Because of their size, appetite, and activity level, they’re especially popular in reptile enclosures where a robust cleanup crew is needed. They may not be rare, but they’re trusted for a reason.

Reliable. Productive. Zero drama.
