A couple of days ago during a cage clean out I was trying (carefully!) to extricate one of my hisser nymphs (born in January) from a crevice in piece of cork bark I wanted to move out of the cage. It really, really didn't want to budge, so I was trying to persuade it out by pushing it gently with a soft artist's paintbrush, when I heard this soft, quiet little hiss. At first I assumed I was just hearing one of the adults hissing from further away, but when it hissed again I could see its little abdomen contracting and it was definitely coming from the nymph
That's the first nymph born in my care that has grown big enough to hiss, and after all the disappointments of the first few months of owning hissers, during which one of my females and the small number of nymphs she gave birth to all died, it finally felt like a proper roach keeping milestone has passed
Yes, I know it's only a silly little thing, but it made me smile!
