I'm wondering if they can be kept with some sort of maybe foul tasting plant, or maybe marimo balls, or java moss. Anything that they won't completely devour and rip to shreds?
I've always heard they don't go well together, but have no personal experience with this. As all my silver dollars were with fake plants.
Mine don't bother the crypts, nibble on the java fern a bit. I can shoot a video, I have pretty lush growth of crypts. The SDs were in the tank years before the plants were added.
