More

The Moosmantis Hannia orlovi is only in breeding since 2016, but was quickly known and sought after because of its extraordinary shape. They are extremely well camouflaged in their natural habitat (moss) thanks to their small thorny extensions. With their body length of about 2 cm they are one of the smallest species in breeding. Nevertheless, it is relatively long living for its size. If you do not keep it too dry and not too hot, it can give you a long lasting pleasure. Also intraspecific, the aggressiveness is very low, because they prefer relatively small food (Drosophila, firebrats or newly hatched springtails).
