Hey Dan, is this for a goldy tank? -your goldies will uproot anything that doesn't have deep root base (ie like small grassy plants like that one...)
you could try hair-grass pots, but you'll have to keep them in the pots, and they don't fare too well in cold water... so, unless you've got a heater in there with your little guys, hmmn, there's nothing really that I could suggest..
