I have just set up a 20L with baby tears in the foreground and micro sword in the mid ground. I was going to use Hygro for the back (might have been a bad idea anyways) but it came in dead. Anyways I am having a hard time deciding on a back ground plant for the 20L because it seems like most plants get to big even some of the mid grounders seem like they get fairly long. Vals were what I originally wanted but I am using some excel with my DIY CO2 and I have heard Vals do not react well to it. Any suggestions for a newbie on something that will remain relatively short (8" to 12") for a 20L and looks somewhat like Vals? 
Thank you for any help or advice you can offer.
