Armadillidium Gestroi (Yello Spotted Isopod)

Armadillidium gestroi “Yellow Spotted”

These isopods are a true standout in any collection thanks to their striking black bodies accented with bright yellow spotting. Growing up to nearly an inch in length, they are among the larger Armadillidium species commonly kept in the hobby.

Because of their size, colonies can take a little longer to establish, but once settled they reproduce at a steady medium rate. Their bold appearance and impressive adult size make them popular both as functional bioactive cleanup crews—breaking down waste, aerating soil, and cycling nutrients—and as display pets for collectors who appreciate their unique look.

Whether you’re building a bioactive enclosure or expanding your isopod collection, Armadillidium gestroi offers both utility and beauty in one hardy, eye-catching species.
