Well at least she's a pretty hateling!
We just got our first really nasty corn. We've only had him three weeks now - but I'm just getting the impression that his striking at me and tail rattling isn't going to go away with careful attention and age. I think that may just be his demeanor. =] It's cute when they're as small as my little guy but I can imagine them causing some pain later on!
I find they calm down a lot more once they're out of their tanks and into your hands. Boo goes S-shape and darts away if I don't scoop him right up when handling, but once in my hands and away from his tank, he's a calm boy... if I don't let him near the ground. He tries to dart out of my hands if I get too close to the ground, but once he gets bigger he won't be able to fit under most of his potential hiding places.I have some that were that way as babies but after a LONG time realizing that they weren't going to be eaten, they calmed down, some surprisingly so. Most actually seem to. If they strike, I just ignore it.
I'm hoping! He is pretty tiny, yet - so I'm hoping it will pass in the next year or two.
How old is Ivy?
