The Marbleized Isopod (Armadillidium Espanyoli) is a smaller sized armadillidum from Spain. They have an aesthetically pleasing light to dark beige coloring intermixed with a creamy off white. The patterning is unique on each individual, but all have incredible contrast likening their appearance to a modern marble counter top. Some say it conjures up thoughts of espresso and lattes! However you may interpret their appearance, the Marbleized Isopod boasts the impressive feat of taking typically bland colors and making them "pop" just as much as other brightly colored species. They are communal with large numbers of individuals often found huddling tightly together in a tight mass under cork bark or decayed wood.
For housing, a 6 quart gasket sealed storage bin or small glass aquarium is sufficient for a small starter culture of 15 to 30 individuals. Standard or bioactive enclosures can be enhanced with natural botanicals to simulate the isopods habitat in the wild. This helps them feel secure which in turn promotes their natural processes like eating and breeding. Average room temperature will suit them just fine. A good temperature range is 72-80F leaning more towards the warmer end if possible. A standard moisture gradient with around 30-40% of one side moist (not wet) with the remainder tapering off is adequate. Note though even the driest section should still have a nominal amount of moisture in it. They will not fare well if more than a small section of the enclosure gets too dry. A few pieces of cork bark strategically placed over different parts of the enclosure will help retain the humidity levels and reduce the frequency of watering needed to maintain a proper moisture gradient.
Isopods are detritivores. Their primary diet in nature is dried leaf litter and rotting decayed wood. Both of these should always be available in abundance. They will also happily consume any other decomposing organic plant or animal matter they come across. As such it is vital to supplement your isopods with other food sources on a semi regular basis. Marbleized Isopods relish food options like squash, carrots, cucumbers and other veggies along with commercial isopod powdered food like Repashy Morning Wood. They also appreciate some protein once or twice a week so offer them things like freeze dried minnows, shrimp, fish pellets, dried insects and other protein based food sources. Be sure to feed these on the drier side as they can spoil quickly in humid environments and attract unwanted pests.
The Marbleized Isopod is not an overly difficult species to keep, but they are noted as being "slow" to start. It should also be noted they are primarily nocturnal so to truly enjoy those flashy creamy colors you will have to look in on them after daylight hours. Some moving about during the day is not uncommon once your colony has started to reproduce and shows higher density. They are a bit skittish when disturbed and move surprisingly fast for an isopod! A. Espanyoli is a fantastic Isopod worth adding to your collection or simply as a bioactive custodian in the proper environmental set up.
