A very warm welcome to this exciting, albeit confusing, world.
I know it's a bit overdue, but better late then never, right?

I'm sure you'll find your way easily, @abh12345 can guide you along, he seems to have some experience already ;-)

Love to hear about your experiences, old and new.

And I'm quite sure plankton just floats, but then again I've never seen a shoal/herd/gaggle/flock of plankton, so what do I know?

Have fun and till we meet again.
