No Peanut Butter, but. . .

Newest official member of my fishtank--hydroid jellyfish. I have seen 6-7 of these in the tank. This one is one of the largest, and is only half an inch, including all of the tenticles. These will most likely disappear in a couple months, never to be seen again.

The first picture is from other other side of the glass, where it is attached. The second is a side shot.
