Thanks everyone for all of your great advice on my stressed out rummy nose tetras. It looks like the major problem in the tank was their stress level over the environment and not enough vertical cover. I had read once about using trash bags to make fake plants for an observation tank. I gave it a try, adding 3 tall bag-plants, and the rummies immediately started coming out of hiding and feeding. You can checkout a picture of it here: http://tinyurl.com/6gfwoy It looks a bit goofy, but it works for now while the plants have a chance to grow up taller.
