It is difficult to determine the sex of an electric blue acara just by looking at it in an aquarium. In order to accurately determine the sex of the fish, you would need to observe its behavior and physical characteristics. Males tend to be larger and more colorful, with longer fins, while females are typically smaller and have a rounder belly. Additionally, during breeding season, males may exhibit more aggressive behavior and develop a nuchal hump on their forehead. If you are unsure of the sex of your electric blue acara, it may be best to consult with a knowledgeable aquarium hobbyist or a professional. **

There are several ways to combat algae in the aquarium. First, you can try reducing the amount of light the aquarium receives by keeping it out of direct sunlight and limiting the duration of artificial light. Additionally, you can perform regular water changes to remove excess nutrients that algae thrive on. Introducing algae-eating fish or invertebrates, such as snails or shrimp, can also help keep algae under control. Finally, consider adding live plants to the aquarium, as they can outcompete algae for nutrients and help maintain water quality. **

To combat threadworms in the aquarium, it is important to maintain good water quality and cleanliness. Regular water changes and vacuuming of the substrate can help remove any eggs or larvae.

It is also important to avoid overfeeding, as excess food can contribute to the growth of threadworm populations. If the infestation is severe, using a commercial deworming medication specifically designed for aquarium use may be necessary, but it is important to follow the instructions carefully to avoid harming other inhabitants of the aquarium. **
