Roly-Poly Revolution: The Amazing World of Isopods!
Southern Colorado, did you know that the familiar little "roly-polies" you used to find under rocks in the backyard have completely taken over the exotic pet hobby?
Check out these incredible photos we snapped of the Skewbald (Porcellio scaber) isopods currently hanging out in the shop! While isopods are famous for being the ultimate "Clean-Up Crew" in bioactive reptile tanks, an explosion of breathtaking designer morphs has made them incredibly popular as standalone display pets.
Fun fact: Isopods aren't actually insects at all! They are terrestrial crustaceans, meaning they are closely related to crabs and shrimp, and they actually breathe through modified gills on their undersides!
The Beasties Bug Lineup
Whether you are looking for a bioactive cleaning crew or a fun new desktop pet, the variety is endless:
- The Skewbald (Porcellio scaber): The stars of our photos! These guys are hardy, bold, and boast a beautiful, highly variable blotched pattern of whites, browns, oranges, and blacks.
- The Dairy Cow (Porcellio laevis): One of the most famous isopods in the hobby! They are large, active, and sport a striking white body covered in random black splotches, looking exactly like tiny Holstein cows.
- The Dwarf White (Trichorhina tomentosa): The ultimate bioactive clean-up crew. They are tiny, spend all their time burrowed in the soil, and actually clone themselves without needing males!
The Moisture Gradient
Because they breathe through gills, keeping them in our dry high-prairie climate is the most important part of their care. You have to ditch the open-screen tanks!
- The Bin: Standalone cultures thrive in plastic storage bins (shoebox size) with very small, controlled ventilation holes drilled into the sides.
- The Gradient: You cannot make the whole bin wet, or they will drown! You must create a "wet side" (a large handful of damp sphagnum moss on one end taking up about 25% of the space) and leave the other 75% of the soil completely dry. They will travel to the wet moss to breathe and rehydrate, but will use the dry side to forage and shed their exoskeletons!
The Recycler Diet (Don't Forget the Protein!)
For an isopod, their substrate is both their home and their primary food source!
- The Edible Dirt: Standard potting soil won't work. They need a rich base of organic topsoil and decayed hardwood, completely covered in a thick layer of hardwood leaf litter (like Oak or Magnolia).
- Building Shells: Because they are crustaceans, they need calcium to build their exoskeletons! We recommend mixing in crushed eggshells or leaving a piece of cuttlebone on the dirt.
- The Cannibal Risk: Fast-breeding, active species like our Skewbalds and Dairy Cows are incredibly protein-hungry. If you don't supplement their diet with high-quality fish flakes, freeze-dried minnows, or a specialized bug diet, they will actually eat their own babies!
