Common Hisser 

One of the most famous cockroaches in the world is known for the incredible hiss they expel as self-defense. These hissers are very common at pet stores for sale and get around 2-2.5 inches and have awesome black stripes with orange abdomens. Males have horns on their pronotums to fight other males for a female to breed with. There are around 20 known species of hissers and this is the most common and well-known I have been keeping these guys for a few years now.
