Here we have an individualist in aquatic plants. The beautifully shaped leaves have a specific fascination of their own. The Cryptocorynes aren’t lovers of strong light, so if your aquarium is placed in a shady position, these are the plants to use, but it’s well to keep in mind that they do need some light stimulus, so don’t overdo the shading. Simply because the quantity of light needed for Cryptocoryne is less than most aquatics it’s obviously much better to use only plants of this nature in one tank, otherwise you’ve to compromise between supplying strong light for some plants, along with a weaker light for others, and end up satisfying neither.
