I have three turtles in my tank currently, and they are all nosey little buggers when ANYONE comes into the kitchen/ dining room!
On reaching into the cupboard under the tank I noticed two of them (Squirt and Penny) swimming around where I was kneeling, which is pretty normal, then I noticed Spanky lean over the floating dock and poke his head into the water to get a view of what I was doing...
When he did this I raised myself up to past the water level and as I did that he followed suit and took his head out of the water... Then as a big kid I ducked down again so he was out of sight - once again he dipped his head into the water...
This went on for several more times, until I called my brother in to see it. I never realised before just how nosey or inquisitive they are...
Just thought I would share...
