Are Electric Yellow Cichlids Aggressive

How do You Tell the Difference Between a Male and Female Electric Yellow Cichlid

The electric yellow cichlid is a stunning fish. However, telling the difference between males and females can be challenging. Here are a few ways you can tell the difference between a male and female electric yellow cichlid:


Both male and female yellow lab cichlids have stock and elongated bodies. The fish has black stripes along its dorsal fin, which will darken as it matures. However, the male yellow cichlids have ventral fins and black annals, which the female do not.

Also, the dominant electric yellow lab cichlids have scales that appear almost goldish and have a brighter yellow color than the female. In addition, the male may have light spots on the fins, which are not present in females.


The male and female electric yellow cichlid size also differ. The male is larger than the female. Male yellow lab cichlids can grow up to 5 inches, while female grows up to 3 inches in length.


The female yellow lab cichlid is a mouthbrooder. It means that the female will carry eggs in the mouth for about three weeks. During that period, the fish will not eat anything. However, the male will continue to eat.


The male and female yellow cichlid are nonaggressive when they have ample space in their tanks. However, the females tend to be more protective if they carry eggs, while the males are more aggressive when searching for mates. Also, in an overcrowded tank, the male is more aggressive than the female.

What do Electric Yellow Cichlids Eat

The electric yellow lab cichlids are omnivorous. They will consume small invertebrates such as snails and crustaceans in the wild. However, the fish can consume anything in the aquarium, though it is always good to provide them with live or frozen foods.

In addition, note that meat-based foods are vital for their breeding and growth process, but too much protein is not suitable as it can cause Malawi bloat. Therefore, balance the feeds between animal and plant diets for a healthy electric yellow cichlid.

You can provide your fish with algae tablets and freshly blanched vegetables. Other foods you can consider giving your fish include blood worms, mysids, dried shrimp, and high-quality flake foods.

If you give your yellow lab cichlid bloodworms and shrimps, ensure they are dead or dried. Also, give your fish vitamins and supplements like Carotene. The supplements will facilitate healthy growth. For feeding, give your electric yellow cichlid small food portions throughout the day instead of one large serving.

In the tanks, make sure to have plenty of rocks. The rocks will provide good hiding spots for your fish. Also, ensure you have fresh water with temperatures between 74ºF and 84ºF. The pH should be 7.2 and 8.8
