The electric mermaid has a mild and lively temperament and can be mixed with small fish. Electric mermaids will be more beautiful in the case of light, so raising electric mermaids requires a certain amount of light. General aquariums can install 40-60 watt fluorescent lamps, and turn on the lights for 6-10 hours a day.

Because the electric mermaid's dorsal and anal fins are bright red, and the caudal fin is pale Red, so the electric mermaid looks like a reddish blue ghost under the lights. Feeding electric mermaids should also pay attention to scientific feeding methods. It is recommended to feed brine shrimp, water fleas, silk earthworms, and other live bait for this small tropical fish.

But remember to pay attention to the amount of feeding. If you can't eat too much feed, it will pollute the water quality and cause the opposite effect. The amount of bait should not be too much, so as to avoid the electric mermaid not eating enough and polluting the water quality.
