Anubias is a genus of aquatic, semi-aquatic, and semi-terrestrial plants that are widely used in the hobby of aquascaping. It is an extremely hardy and resilient plant that can survive in a wide variety of water parameters and temperatures. Anubias is often touted as the ideal plant for beginners and those who are just getting into the hobby. Despite its hardiness, however, Anubias does have one major problem: it melts.
Anubias melts when the water parameters are not optimal for the plant, or when the plant is subjected to sudden changes in the water parameters. The most common cause for Anubias melting is an increase in nitrate levels in the aquarium. Nitrates are essential for the growth and health of aquatic plants, but too much nitrate can cause the leaves of Anubias to turn yellow and eventually melt away. Other causes of Anubias melting include sudden changes in temperature, excessive light, and an imbalance of other essential nutrients.
Fortunately, there are a few simple steps you can take to prevent Anubias melting. The first step is to maintain a stable water temperature. Anubias is a tropical plant and prefers temperatures between 74-86°F (23-30°C). Sudden drops or increases in temperature can cause Anubias to melt. Additionally, it is important to provide sufficient light for Anubias. Anubias can tolerate low light levels, but too much light can cause the plant to melt.
The second step is to maintain stable water parameters. Anubias prefers slightly acidic to neutral water with a pH of 6.0-7.5 and a water hardness of 5-15 dGH. It is important to keep these parameters stable to prevent Anubias from melting. Finally, it is important to provide sufficient nutrients for Anubias. Anubias requires a balance of macronutrients (nitrogen, phosphorus, and potassium) and micronutrients (iron, calcium, and magnesium). Anubias can be fertilized with liquid fertilizer, root tabs, or slow-release fertilizer.
The third step is to avoid sudden changes in the water parameters. Sudden changes in the water parameters can cause Anubias to melt. It is important to add new water slowly and avoid large water changes. Additionally, it is important to avoid using tap water if possible, as tap water can contain chlorine and other chemicals that can be toxic to Anubias.
Finally, it is important to monitor the health of Anubias. If Anubias begins to show signs of melting, it is important to take action immediately. Check the water parameters and adjust them as needed. Additionally, check the amount of light and adjust the lighting as necessary. It is also important to check the nutrients and fertilize as needed.
Conclusion
Anubias is an extremely hardy and resilient plant, but it can still suffer from melting if the water parameters are not optimal or if the plant is subjected to sudden changes. To prevent Anubias from melting, it is important to maintain stable water parameters, provide adequate light and nutrients, and avoid sudden changes in the water parameters. Additionally, it is important to monitor the health of Anubias and take action if it begins to show signs of melting. With proper care, Anubias can be a beautiful and long-lasting addition to any aquascape.
