Porcellio expansus, also known as the Giant Spanish Isopod, is a fascinating species that is becoming increasingly popular among isopod enthusiasts. Here's a breakdown of information about them:

Appearance:

• Size: As their name suggests, they are one of the larger isopod species, reaching up to 35mm (over 1 inch) in length.  

• Coloration: They typically have a dark brown or black base color with lighter, often yellowish, markings or patterns. The exact pattern can vary between individuals.

• Shape: They have an elongated, oval-shaped body, typical of Porcellio isopods.

Habitat and Care:

• Origin: Native to Spain and surrounding regions.  

• Environment: They prefer a semi-arid to temperate environment with good ventilation.

• Temperature: They thrive in temperatures between 17-26°C (63-79°F).

• Humidity: They require moderate humidity levels, with a portion of their enclosure kept slightly moist.

• Substrate: A mix of dry leaves, rotting wood, and some damp substrate like sphagnum moss is ideal.

• Enclosure: They need a spacious enclosure due to their size and territorial nature, especially among males. A 12-liter container is recommended for a starter colony, and a 25-liter container for a larger colony.

• Food: They are detritivores, feeding on decaying organic matter, leaf litter, and wood. They also consume fruits, vegetables, and protein sources like fish flakes or dried shrimp.  

Other Characteristics:

• Activity: They are primarily nocturnal, being most active at night and in the early morning.  

• Temperament: They are generally peaceful, but males can be territorial and may fight with each other.  

• Breeding: They have a relatively low reproduction rate compared to some other isopod species and are considered seasonal breeders.

• Lifespan: They can live for several years with proper care.

• Clean-up Crew: While they do contribute to breaking down organic matter, they are not considered as efficient cleaners as some other isopod species.

Important Notes:

• Territoriality: Due to the territorial nature of males, it's essential to provide ample space and hiding places to prevent aggression.  

• Ventilation: Good airflow and ventilation are crucial for their health.

• Diet: They can be picky eaters, so offering a variety of food options is important.
