its risky.... from my experience, the plant that endured the sd's the best was anubias. there would be chunks missing from the leaves, but i believe my severum did the damage. everything else was eaten.
i used to have SD's and i would go out a buy them a peice of hornwort or some other cheap plant once a week as a treat and they would ALWAYS eat it when i did decide to try and plant their tank a bit i tried java fern which supossedly is bitter and notihng eats it and geuss what ?.... they still ate it
they'll eat any plant you throw in there (probably)
I have hornwort in there right now, been 3 days I catch em nibbling but nothing severe. When I pick up some java fern I am gonna buy a big bunch instead of small plants, could fair out better.
