What You'll Learn

Electric blue rams are a dwarf species
Being a dwarf species, electric blue rams remain small even at full maturity. The average length of an adult electric blue ram is between 2 to 3 inches, with some individuals reaching up to 3.5 inches. They are considered relatively small fish compared to other cichlids. Their small size means they do not require massive aquariums, but they still need ample swimming space and territory. The recommended tank size for a pair of electric blue rams is at least 20 gallons, with larger tanks accommodating more fish and paving the way for a multi-species habitat.
The electric blue ram's dwarfism is also reflected in their short life expectancy, typically living for only 3 to 4 years. Despite their small size, these fish exhibit territorial behaviour during the breeding period, requiring a large enough aquarium with hiding spots and natural borders to mitigate aggression. They are known to be protective of their young, taking turns guarding their eggs and rounding up their fry into a school.
In terms of physical features, electric blue rams have long, rayed fins, with a spiky dorsal fin stretching from the gills to almost the caudal fin. The leading edge of the dorsal and pectoral fins typically feature high-contrast black stripes, creating a noticeable outline. Their eyes are bright red and often have a dot or stripe of black. Distinguishing between males and females can be challenging as both sexes display vibrant colours. However, males are usually slightly larger with longer dorsal fins, while females tend to have rounder bellies.

They grow to around 2-3 inches in length
Electric blue rams are a stunning freshwater species, with bright blue colouring, a peaceful nature, and inquisitive personalities. They are a dwarf species of cichlid, and as such, they don't grow to be very big at all. In fact, the average electric blue ram cichlid size is around 2 to 3 inches in length at full maturity. Males tend to be slightly bigger than females once sexually mature, with longer dorsal and pelvic fins.
Given their small size, electric blue rams don't require massive aquariums, but they do need ample room to swim around and establish their territories. The smallest tank size for an electric blue ram is 20 gallons, which is big enough for a pair of these fish. However, a larger aquarium is always preferable, as it will allow you to keep more fish and create a multi-species tank. More space also means more flexibility and a lower likelihood of territorial aggression.
It's worth noting that electric blue rams can be quite sensitive and can be difficult to keep in captivity. They require a stable environment with low levels of organic waste, good filtration, and regular water changes. The water temperature should be set at the high end of their preferred range, and the water should be very soft with a pH of less than 7.0. Additionally, electric blue rams need peaceful and docile tankmates, and they should not be kept with other dwarf cichlid species.
Breeding electric blue rams can be challenging, as they become more aggressive during the breeding period. However, they are known for their parental care, with both males and females taking turns guarding their eggs and fanning their fins to prevent bacteria and fungus infections. The female electric blue ram typically lays up to 300 eggs, which hatch in about three to four days, and the fry become free-swimming about five days later.

The males are usually slightly bigger than females
Distinguishing between male and female electric blue rams can be challenging. Unlike most fish species, female electric blue rams are just as vibrant in colour as males. However, the males are usually slightly bigger and have longer dorsal and pelvic fins. Being a dwarf species, these fish do not grow very big. The average electric blue ram cichlid size is around 1.5 to 3 inches in length at full maturity.
The size of an electric blue ram can depend on its genetics. Some believe that the more inbred individuals may be the ones that grow larger. The size of the fish is not as important as their health and lifespan. As long as they live to a healthy age, a smaller size is not an issue.
Electric blue rams are difficult to keep in captivity. They are generally quite sensitive, and it is important to provide them with the correct environment to ensure they stay happy and healthy. They are a relatively small fish, and their small size means they do not require massive aquariums. However, they still need ample room to swim around and establish their territories. The smallest tank size for an electric blue ram is 20 gallons, which is big enough for a pair of electric blue rams.
The majority of electric blue rams sold at pet stores are juveniles, so they will be considerably smaller than fully mature adults. They have a fairly short life expectancy of just 3 to 4 years.

They are territorial towards their own kind once sexually mature
Electric blue rams are a stunning freshwater species with bright blue coloration, a peaceful nature, and inquisitive personalities. They are a dwarf species and do not grow very big, reaching a maximum length of around 2 to 3 inches as adults. The majority of specimens sold at pet stores are juveniles, so they will be smaller than this, typically around 1 to 1.5 inches.
When it comes to their behaviour, electric blue rams can be territorial towards their own kind once they reach sexual maturity. This means that a bigger tank is often required to spread out any aggression. Providing ample space to swim and establish territories is crucial. The smallest tank size for a pair of electric blue rams is 20 gallons, but larger tanks of 30 to 40 gallons are recommended to reduce territorial aggression and allow for more fish.
The territorial behaviour of sexually mature electric blue rams is not limited to their own species. They can also be territorial towards other fish species in the aquarium. Therefore, it is important to choose tank mates wisely. Slow-moving and tranquil species that won't outcompete the rams at mealtimes are ideal. Small and peaceful fish, such as Corydoras catfish, hatchetfish, pencilfish, small tetras, and suckermouth catfish, are good choices.
In addition to providing a large enough tank and choosing the right tank mates, there are other factors to consider when keeping electric blue rams. They require a stable environment with low levels of organic waste, good filtration, and regular water changes. As they originate from a warm climate, an aquarium heater is also necessary. Hiding spots and natural territorial borders, such as live plants, driftwood, and Indian almond leaves, can further help to reduce aggression.

A bigger tank can help reduce aggression
Electric blue rams are a stunning freshwater species, with bright blue coloration, a peaceful nature, and inquisitive personalities. They are a dwarf species and do not grow to be very big at all, with a maximum length of around 2 to 3 inches as adults.
A bigger tank can definitely help reduce aggression in electric blue rams. These fish can be territorial towards their own kind, especially once they reach sexual maturity, so providing them with more space can spread out their aggressive tendencies. A larger tank allows them to establish their territories and have ample room to swim around. The smallest tank size for a pair of electric blue rams is 20 gallons, but it is recommended to go up to 30 or 40 gallons if possible. This not only gives them more space but also allows for a multi-species tank, as long as their tankmates are slow-moving and tranquil species that won't outcompete the rams.
In addition to a bigger tank, it is important to provide hiding spots and natural territorial borders within the tank. This can include live plants, driftwood, and Indian almond leaves. Flat stones or breeding slates are also recommended, as the female ram will clean a stone or dig a pit in the substrate prior to spawning. During the breeding period, electric blue rams become more aggressive as they work to protect their eggs and young. Therefore, it is crucial to provide them with ample space and hiding spots to reduce this aggression.
It is worth noting that electric blue rams are sensitive fish, and providing them with the correct environment is essential for their well-being. This includes maintaining stable water parameters, regular water changes, and good filtration. Additionally, as they are native to the warm tropical regions of South America, their tank should be equipped with an aquarium heater to replicate their natural habitat.
