I've had my het pieds in together since Nov 1st and I've yet to see any kind of action. Last night I checked on them and noticed that both of their tails were lined up, but no lock. This morning I checked on them again and they were now over lapping each others tail, but still no lock. I just got home and checked on them again and THEY ARE LOCKED UP!
*Does the happy snake lock up dance*
I'd post a picture, but I'm not going to disturb them since this is both of their first times and knowing my luck the flash will make them spook and separate.
