have about 12-15 hissers. have checked them all out and im not sure if i have any males...some of them are differently shaped (longer vs. stubbier) but havent noticed any "horns" or furry antennae. did i just get unlucky and not get a male??? the majority are about 1.5 to 2 inches, adults??? any other help with sexing or special ways to tell would be greatly appreciated!!!
