I personally like #5. If it was me, I'd get some Java moss and spread it along the top of those roots so that it's half out of the water, then maybe get a small philodendron and plant it in the fork up at the top. Phils love being able to run most of their roots into water.
My adventures in keeping Indostomus crocodilus, the crocodile toothpick fish. AKA armored stickleback, paradox fish, and freshwater pipefish. Care is (to the best of my knowledge) exactly the same as Indostomus paradoxus.
