I bought a live java fern from a petstore called Petco and I'm not really sure if it's a real aquatic plant or not. The java fern came in a long, round, plastic container and on the bottom of the container was a jello-like substance. It was sold on the shelf with other plants. The plants were not in an aquarium. On the package, it was not called java fern, but rather tropica fern. Although the latin name is microsorium pteropus. The company that produced the so called tropica fern is Complete Aquatic Systems (this information was on the back of the package) Will this java fern live? Has anyone bought this type of java fern from this company before?
