   The Onion Plant is a great and hardy plant for many aquariums because it's leaves are extremely tough, making it suitable for aquariums with larger fish!

Onion Plants are easy to care for and adapt well to most aquarium environments. They can grow to an impressive height of 60 inches (150 cm), with their leaves being about 0.8 inches (2 cm) across. Their leaves are extremely long and ribbonlike, and will start growing along the surface of the water once they reach it. Once they are well established you can cut the leaves back some to keep them from growing too long. Because of their height and long leaves they make great background plants for aquariums.

As long as the light is kept moderate to bright, Onion Plants will expend a moderate growth rate. As stated above, they adapt easily to most environments, so as long as the water is kept fertilized with nutrients, the water is cleaned on a regular basis, and the ph is kept around neutral, this plant should thrive. It is also relatively easy to propagate by simply planting the daughter bulbs that are produced.

So I planted some Water Onion bulbs a couple of days ago and on some of the bulbs there is some white cloudy stuff starting to appear and I wasn't sure exactly what that was? Should I remove the bulbs? Is this dangerous to my fish? Any information would be helpful and thank you in advance!

    The white cloudy stuff is probably mold?

I bought some moneywort from petsmart, and a leaf of onion plant made it into the bag (and my tank), do you think this will grow?

  • Charlie Roche - 2011-06-27
    Might as well try. Usually they propagate via the offshoot bulbs. I have no idea if a leaf can actually root but no reason not to try. Right?
  • Alan - 2014-03-28
    If you haven't got your answer. NO... The leaf will not produce roots with this plant.

Maybe this is kind of stupid, but is this plant edible? (eat-able?)

  • spencer - 2011-01-07
    To you, it tastes horrible but to the fishes, it tastes nice.
  • Angie - 2012-01-26
    NO.
    It's NOT an actual onion.

    It's poisonous if ingested. Most fish and other aquatic life leave it ALONE due to the fact, that it doesn't taste good to them.

    Hoped I helped! :D
