This is where you will basic info on how I care for my isopods and springtails. My way may not be perfect for everyone and it is not the only way to do things.
The individual species pages will give care specifics if they need something special beyond the care info provided here.
What do you keep your isopods in?
Most of my isopods are kept in plastic storage containers. Shoe box or sweater box size is adequate for even sizeable colonies of most species. Some of the larger Porcellio species benefit from more space, I set those up in 36x16 footprint "under bed" storage containers. The containers need to be vented, some species require a lot of ventilation, others are perfectly happy with very little. I have used a number of methods. Some I just open every day to refresh the air, some are vented with small holes burned with a hot needle or soldering tool (be careful using hot things, wear thick burn resistant gloves if heating a needle), some have larger vents cut or burned in the lid and/or sides and then covered in screen. Keep in mind any ventilation needs to still keep the isopods in and also ideally keep spiders, other bugs, and flies out. There are 1" to 3" metal vents with screen or plastic vents with air holes that can be snapped or clipped into the container sides or lid after cutting with a hole saw. We have been frequently using these most recently.
What do you put in the boxes?
Typically they have a couple of inches of organic potting mix mixed with coconut coir or ecoearth. For some species I use Reptisoil on the dry end as I find it tends to be somewhat hydrophobic until it is fully saturated.
On top of this I may add some or all of the following: hardwood leaves, grass hay, corrugated cardboard, sphagnum moss, oak chips, reptibark, cork bark, hardwood bark, rotted wood, egg crate, and/or twigs.
What do you feed them?
My isopods eat a wide variety of foods. The majority of their diet is made up of premium fish foods, flakes and pellets. They also receive fresh veggies, spirulina powder, brown rice flour, hardwood leaves, grass hay, occasionally small pieces of fruits and meats. Repashy Morning Wood powdered diets and dried crystal river shrimp are also offered from time to time.
They require a calcium source to form and maintain a good shell. The easiest way is to provide a piece of natural cuttlebone inside their bin. I also choose to occasionally supplement with calcium carbonate powder.
How often do you feed them?
I typically feed my isopods only as much as they will eat in a day or two. Occasionally I use foods which are capable of lasting much longer (like carrots, squash, and potatoes) those I will put in in larger quantities and keep in there until they are gone. With potatoes it is important to pinch off or otherwise remove sprouts.
What conditions do you keep them in?
Temperature: The room my isopods spend their time in stays between 65F and 75F for most of the year.
Humidity: I do not measure the humidity in the individual containers. The room is typically 55%-65% ambient humidity year round due to the fish tanks that share the room. The dirt in each bin is kept damp in at least one part if not all of the substrate.
