@Gideyon Are you ok with attaching the plant to wood or a rock with sewing thread?
If so Anubius or Java Fern will do ok in low light. You can purchase Anubius in plastic containers Petsmart or maybe Petco.
@JosiahBass My mom had one many years ago but she fed it live guppy feeders. That was the trend back then. I would definitely get it on sinking pellets. Give a little time to adjust to it's new environment.
Many years ago I personally would use feeder goldfish for freshwater and damsels for saltwater setups. Now that I have a sump pick out sponge, or other biomedia to jump start cycle. I won't sacrifice live fish anymore.
