6 “Aquarium” Plants to Avoid
Fountain Plant (Ophiopogon japanicus) So-named for the gushing appearance of its foliage, the fountain plant commonly appears as an aquarium species. Its long, thin leaves may exhibit attractive white edging and striping. It is highly adaptable and may subsist for many months completely underwater but should quickly be removed to a drier environment if leaves start to die. The fountain plant is best used as a marginal in a warm to slightly cool (64-79° F) environment. Depending upon the variety, it can grow to anywhere between a few inches to well over a foot in height.,Stardust Ivy (Syngonium podophyllum) The stardust ivy is available in many color varieties with white veining, spotting or frosting. It can reach heights of about a foot but is usually a bit shorter. This popular and widely available climbing houseplant is normally grown completely out of water. Stardust ivy will die almost immediately if its leaves are flooded. On the other hand, it can live and grow partially submerged with its long roots trailing into the water. Some hobbyists plant small cuttings in the rockwork of paludaria and terraria with great success. So long as its leaves and stems are allowed to breathe, this plant is undemanding and will thrive under a variety of light conditions.,Image via iStock.com/takepicsforfun By Kenneth Wingerter It’s fairly easy to cultivate most live aquarium (that is, aquatic) plants. If you keep your aquarium plants well-nourished, as well as provide appropriate lighting and water flow, it should be quite simple to maintain many lush aquarium plant species. But they must be true aquarium plants. We are seeing a sort of renaissance in the planted aquarium hobby. Aquatic plant enthusiasts presently have a broader selection of species to choose from than ever before. While choice is always a good thing, there are certain species of plants that may be found in the trade but, nevertheless, are unlikely to flourish under typical aquarium conditions. Among these are a handful of terrestrial and emergent plant species. Breaking the Surface Terrestrials are true land plants that inhabit dryish environments. Emergents are subaquatic plants that live (i.e. root) in water but send the majority of their leaves and stems above the water surface. While some true aquatic plants bear flowers that slightly breach the water surface, they otherwise must live entirely underwater. The all-too-common retail merchandising of nonaquatic plants (sometimes slickly labeled as “decorative” varieties) alongside true aquatic plants might be taken by some to mean that they can survive and grow completely underwater in aquaria. Even so, these types simply cannot tolerate a subsurface existence for long; some species might survive for months submerged, while others pretty much die immediately. Do note that most of these nonaquatic plants are extremely easy to keep in an appropriately constructed paludarium (i.e. riparium) or wet terrarium. In actual fact, many such species may be kept “in” aquaria if grown under aquaponic conditions—that is, if they are positioned in a way that allows only the lower parts of the plant to remain submerged. For example, some small emergents or even terrestrials may grow well from fish tank accessories like the cartridge chamber of a hang-on-the-back filter. Additionally, quite a few cold-hardy varieties may be kept outdoors as marginals in small ponds or container gardens. Here, we identify and discuss six nonaquatic plant species that may be found in the aquarium trade but, nevertheless, should not be used in the conventional planted tank.
