I have just come into possession of this plant/tree and I'm hoping to find out three things: - What it is - How to look after it - If I can train it I don't know much about it except that it is over 15 years old (probably much more but I don't know much of its history) and it's always been in this same pot. There's a rather dense moss growth in the pot, too. I'm in Melbourne, Victoria, Australia (if that helps with care guidelines). With regards to training, I don't want to do anything too dramatic; mostly just stop it growing a way that will tip the pot over - just evening it up a bit. I've attached two photos - one of the whole thing and one (rather poor one) of the leaves and branches in case that helps with identification. I'm told it's a succulent which makes sense because the leaves are quite turgid. Some of the leaves are slightly yellowed with speckles on them - should I be worried about that? I don't mean to ask too much; any information about it would be a huge help. Thanks heaps.
