So there's two new things that well I didn't put in there that I've no real clue what they are. The first is this little blue thing, it seems to move around a bit, not much just kind of ends up in a new spot now and then though I haven't actually seen it move. so it could just be rolling around for all i know.
The second might appear to be some coral? Both are small hard to get a good picture of them really, but its red in color almost appears to maybe be some sort of hard coral. Not real sure?
