| 產品詳情 |
Fascinating to watch, these predatory insects grab prey, which includes other insects, and small fish, with their extendable mouthparts.
They also feature rectal gills for survival in water and move by expelling water through their anus. The specimens may spend several years as nymphs before maturing into dragonflies. They will eat other small aquarium inhabitants.
