If you see this happen, don’t throw away your “dead” plant! Leave it planted in the substrate, and once it has adjusted to your water chemistry, it'll quickly rebound and grow new leaves. Much like Amazon swords, crypts leaves are known for melting back when they’re first added to a new tank.

To better enhance the redness of its leaves, consider dosing extra iron supplements to the aquarium water. Crypt wendtii comes in many varieties, such as green, brown, tropica, and red. It does prefer to feed from its roots, so if you use an inert substrate that doesn’t have many nutrients, make sure to regularly add root tabs every three months or so for optimal health.

Eventually, the sword may grow big enough to become a mother plant, creating long spikes that turn into baby sword plants for you to plant in other aquariums. If these new leaves appear to be yellowing, make sure to give it more root tabs. Once placed in water, these large leaves melt back as the plant reabsorbs their nutrients to make longer, narrower leaves that are submersed grown (or grown underwater). When you first buy it, the sword usually has big, round leaves that are emersed grown (or grown outside of water).
