Definitely a good idea to shorten the tube if you can. Also, remember not to cover the hard rhizome of the anubias and java fern with sand if you decide to not tie those to rocks of wood. Just a reminder. A great thing to do would be to google each type of plant you have, something like "how to plant crypts" or "how to tie java fern to rock". Couldn't hurt!
