When it comes to choosing the best lotus for your fish tank, there are a few things you should consider. The most important factor is what type of environment you want in your aquarium. If you're looking for an exotic and vibrant atmosphere, then a hardy tropical water lily such as Nymphaea Lotus would be perfect. This variety features large showy flowers with fragrant blooms that come in colors ranging from pink and white to yellow and orange. They also grow up to two feet tall making them great centerpieces in any aquarium setup. On the other hand, if you prefer something more low-key and natural looking, then an American White Water Lily (Nuphar luteum) may be a better choice. These plants have smaller flowers but they still offer plenty of color with their pale yellow blossoms and provide excellent shelter for fish by creating shady spots among its leaves. No matter which lotus species you choose, make sure it's compatible with your tank's temperature range so that it can thrive happily in its new home!
