I have a bare bottom tank and love the look of Val that I have seen in aquariums as a background or running across the top. Is there a Val or type or tall grass (8-10 inches) that I could use in the aquarium by placing it in a container so that it would live? If so, what type of soil,sand,etc would been needed? I have African dwarf frogs that hang out on some rock ledges and the fake plants near the top. I have Anubis’s and Java Fern Windelow, but they do not get very tall. I have tried hornwort and water sprite and they did not last long. Water sprite wilted away when it was anchored down and did not come back. The hornwort did fine, but clogged up my glass intake with the small pieces that came off. Any suggestions for plants that work well in a container and what is needed to keep them thriving would be appreciated.
