I might double-post this......to hit the "aquatic plant" forum AND the "indoor tank" forum...... What are some good and dependable plants for an indoor tank? In the past I just used what I pulled from the pond, but hornwort & ancharis never did well and weren't really the look I was going for. This is a 20 gal. tank, 20H, I believe. I am keeping a bare bottom [the tank.....], but maybe there is something that would grow in a nice, low bowl -- with kitty litter, sand, gravel, marbles, etc.... -- as a substrate? Don't need a lot plantings, but something so the tank doesn't look bare [with it's bare bottom, LOL!]. I will have a couple of goldfish in the tank -- some of my fry from this spring -- just some nice ones to look at and take care of over the winter months.
