The neatest pet and most aggressive pet I have ever owned has been a peruvian centipede.He was a bout 8 inches long and was cool as all get out to watch.And aggressive,,it didn't matter what you put in there for him to eat if he got a hold of it,,it was dead.It was very easy to take care of but not something you wanted to hold.just one of those pets that was a great display piece.Along with my goliath bird eater!
