I must create a horticulture project for my end of year exam(we are doing projects instead of exams). I submitted my idea of making a planted shrimp tank, it was passed. So, have a 2gallon solid glass cookie jar(it was used for my moms goldfish, i had NOTHING to do with it.) The plant of choice, java fern. I have an over abundance of it as is. The bottom will be large and small pebbles and river stones, should be good for the ferns to grasp, i may also add some moss. The center piece will be a piece of drift wood. I don't want to have to use a heater if i can avoid it. Im thinking of just going with grass shrimp(ghosts) i can get them $1 a dozen at the LFS. However, does anyone have anything to add or suggest?
