There is a very big avocado tree outside my door and over the weekend they were trimming some of the branches off.
I think he must have crawled off one of the cut-off branches as I found him on the paving.
He is very fast and scuttled away whenever I got the camera near, so I let him crawl onto my finger and put him in my tank to take pics.
He is tiny with a body length of less than half an inch but extremely hairy as you can see.
