What to tie plants with? Cory likes to dig...

I need to tie down my plants because one of my cories thought it would be funny to uproot two of them; she wasn't entirely wrong but now its created work for me.
So I've seen some people say they use clear elastic bands, but I don't want them to turn white. Saw somebody ask about twine and another caution on fishing line?? I know I don't want to glue them. What do y'all find works best to tie down plants?
I don't actually know what kind of plants these are--they're small foreground plants--I'll post and ask in the ID section. My anubias and java ferns have stayed down

 

I have used both rubber bands and fishing line. I personally like rubber bands because they are easier to work with for me. I usually rubberband the plant to a rock then bury the rock in the sand so the plant stays above the sand but you cant see the rock that much.

 

I tie my java moss with #4 fishing line. I don't see why it couldn't work with other plants too.

 

This more works for anubias but if a plant is close to the glass you could try a suction cup.

 

I’ve used fishing line or clear nylon sewing thread, either works well, just make sure it’s tight enough & don’t leave any trailing threads

 

I prefer the silicone bands that turn white (they fall apart after a few weeks which is handy), or super glue myself. Thread, fishing line, or any kind of twine should work fine as long as it isn't made of natural fibers (like cotton sewing thread). The natural fibers will start to rot eventually if you leave them in the water. Green nylon yarn (like you'd use to make a spawning mop) would work well and blend in a bit.
