- They will come over to say hi if you approach the tank (and they're awake*).
- *It's hard to tell if they're awake because they don't have eyelids.
- They're completely aquatic yet somehow don't seem to be very good at swimming (maybe that's just mine).
- They mostly sit around and move slowly but dangle a worm in front of their face and they will grab it so fast you won't be able to register the movement.
