I just did a Google search of the scientific names of the ferns, and neither of them are even aquatic. One actually is commonly found in woodland forests. This is ridiculous. I am merely an ill informed consumer. Damn you for thriving off of my ignorance, TopFin. How is it possible that they can get away with selling these as plants "for aquariums"?
I know what you mean, I thought aquarium plants meant aquarium plants. RETURN THEM. I bought some when I began my tank, and noticed things happening. I dug through the smelly kitchen trashcan for the tubs and shoved the plants back in and returned them. I did rinse the tubes though... so they weren't tooooo stinky.
