Cryptocoryne Affinis Care

Care for any aquarium is very important, even for the plants you have housed in it. Water Parameters are a key component in caring for Cryptocoryne Affinis. Regular water checks can ensure that your parameters are within the necessary range. Any fluctuations can cause the Cryptocoryne Affinis plant to melt and die. Another important component in caring for Cryptocoryne Affinis is the substrate. You’ll likely want a substrate that is rich in nutrients. Doing so will ensure that your Cryptocoryne Affinis gets all the necessary nutrients it needs. With just a bit of research and proper planning and care, Cryptocoryne Affinis is easy to care for in an aquarium. The most prominent issue for Cryptocoryne Affinis is melting. When a Cryptocoryne Affinis plant melts, it begins to look dead. Unfortunately, this has led some aquarists to believe that they are, in fact, and then they throw them out. In most cases, melting can be easily remedied.

Lighting Requirement

Cryptocoryne Affinis tends to grow more optimally in low lighting. This means that you should ensure that your tank provides it with the amount of lighting it requires. Higher light levels can sometimes cause algae to grow on a Cryptocoryne Affinis plant. On average, you should keep the lighting in your Cryptocoryne Affinis tank low to medium. Warm white fluorescent lights tend to be a good choice. You can likely find the lights you need at any local pet or aquarium specialty store. You can always find them online if they don’t carry them near you.


Temperature is an extremely important water parameter that should routinely be monitored. It is also imperative that you keep your temperature constant and stable. The temperature of your tank should never fluctuate by more than 3 degrees. When keeping a Cryptocoryne Affinis in a tank setting, keep the temperature between 73 to 83 degrees Fahrenheit or 23 to 28 degrees Celsius. A heater is highly recommended. Not only will a heater help you achieve these temperatures in your tank, but it will also help you maintain them. When selecting a heater, ensure that it is high-quality and powerful enough to heat your entire tank. It would also be wise to purchase a simple tank thermometer to monitor the temperature level easily.

Water pH

In any tank setting, pH is an important parameter that should be monitored carefully. Any slight fluctuations in pH level can easily and negatively impact anything living inside of your tank. That is one of the many reasons that it is imperative that you carefully and routinely monitor your water and tank parameters. If your tank contains a Cryptocoryne Affinis plant, you should ensure the pH remains neutral. Most experienced aquarists recommend a pH level between 6.0 and 8.0.

Growth Rate

Cryptocoryne Affinis tends to grow quite slowly in tanks. The main factor that affects the growth rate of Cryptocoryne Affinis is stability. If your water and tank parameters stay stable, this plan will reach its max height in just a few short months. However, any fluctuations in water or tank parameters can cause your Cryptocoryne Affinis to melt, which obviously would negatively affect its growth rate.

Growth Height

The height of a Cryptocoryne Affinis when fully grown seems to vary widely. When fully grown, Cryptocoryne Affinis can reach a height between 4 to 12 inches. This growth height is likely related to the care they are given. If planted in a high-quality substrate with the proper water and tank parameters, your Cryptocoryne Affinis plan will probably be closer to 12 inches when fully grown as opposed to 4. However, that may not always be the case. Some Cryptocoryne Affinis may grow small, despite the quality of care they are given.

CO2 Requirement

As many aquarists likely know, CO2 injections into their tank can be very helpful to the species contained within. However, that is not the case with Cryptocoryne Affinis. CO2 injections tend to cause Cryptocoryne Affinis plants to melt. This is likely because the CO2 injection changes the pH balance in thank. So, in most cases, you should avoid CO2 injections in a Cryptocoryne Affinis tank.


When fully grown, a Cryptocoryne Affinis plant will begin to reproduce. Dense shoots will start to grow off of the base of the plant. You can remove and replant these shoots, effectively creating an entirely new Cryptocoryne Affinis plant.

Where can I find Cryptocoryne Affinis for sale?

As with most fish or plants for your aquarium, you can find them easily for sale online. However, before purchasing online, you should check with local stores to see if they have any. On average, when purchased online, a Cryptocoryne Affinis sells for around $7. If you purchase one online, make sure the dealer is respected. This will ensure that you get the best quality of the plant.
