If you really cant get to a store, you can use silk plants from a craft store. You must make sure, though, that they either have no wire or that the wire is removed from them, that they have none of that fake "pollen" dust or anything of the like, that they're unscented, and you need to soak them a while in warm (not hot) water, to see if they will leech color. If they do, keep soaking them for a while. If they stop and dont anymore, its ok.
@ Pitluvs-Blue Velvet's vase was just shy of 2.5 gallons and it was heated with live plants. He really liked it, but he will be staying in the 5gal. Gonna get him some ghost shrimp buddies or something like that.
And yes I love swords too. That white lyretail male, was actually koi when I bought him. Orange and black splotches all over. Then they just...went away. He now has two faint iridescent blue horizontal lines. I have been keeping fish for a long time including swords and I have never seen that before!
