I feel there more a decoration.

Like most plants you cannot treat your tank with antibiotics or chemical will kill them. Barbs, Silver Dollars any fish that eats plants will tear them apart. Loaches can tear them apart. In most all planted tanks there not really great cause they don't sit still. They will move tumble around the tank sometimes float up. Best setup for them is an all Moss ball tank without to many obstructions to allow them to move around the tank.
hey thanks i dont run a filter cause i live hawaii so its pretty warm here so water will stay cool, the information is really helpful so thanks, the only question i ask is, is it bad to keep it steady buy tying it down to drift wood or is it better to let them roll
