    For lunch today we had cold poached Chilean Salmon. So the Crab and the Turtle also had a special lunch.
    Watching the crab attack the Salmon I was amazed by the complexity of its mouth.
    After the Turtle had eaten its fill it behaved very strangely. It rushed around the tank only stopping to put its head out of the water to take a quick look around. It was obviously delighted with the food or had a tummy ache.

    Matt, I would not touch the identification of freshwater crabs with a barge pole.
    There are supposed to be 13 species in this area divided amongst 7 genera.
    Some of the differences depends on the shape and dimensions of the gonopod.

    I think this kind of behaviour equates to “I’ve been in one place for too long while eating, there might be a predator about, so I’ll put some space between me and my last position”.

    That is a very reasonable and logical explanation.
