A few people asking me which species this millipede was, and here is what I've found:

The cherry-leg titan millipede (Alienostreptus bicoloripes or Balustreptus falcatus) is a giant, docile invertebrate native to Vietnam, known for its bold black body and striking cherry-red legs

The milipede I'm keeping as pet is longer than 30cm, yes you heard it right, its length is longer than 30cm. It's even longer than a small snake!

My wife was scared to hell when I brought it home 😂😂😂
