Overview
The electric blue acara is a captive-bred colour form of the blue acara, a sturdy cichlid whose wild ancestors come from Trinidad and coastal Venezuela.
Its defining trait is an all-over iridescent powder-blue shimmer that the wild-type fish only hints at, usually paired with a dusky forehead and a yellow-orange edge along the dorsal fin.
The morph exists only in the aquarium trade, and its exact ancestry is debated but has never been proven, with many breeders believing ram genes were crossed in early on.
At 12-15cm it towers over this guide's dwarf cichlids and roughly matches a discus in body length, yet it is comfortably the easiest cichlid here.
It tolerates the ordinary temperatures and moderately hard tap water that would slowly kill a German blue ram, and it lacks the spawning-season temper of an angelfish.
Expect 8-10 years from a well-kept fish, so treat it as a long-term commitment rather than an impulse buy.
Housing
Easy care does not mean a small tank, and this is where new keepers most often get it wrong.
Provide at least 200L (55 US gallons) with a 4ft (120cm) footprint for one fish or a pair, because acaras are active swimmers that patrol the whole bottom half of the aquarium.
Keep water at 22-27C (72-81F) with pH 6.5-8.0 and hardness anywhere up to about 18 dGH, and note that unlike rams or discus they genuinely do not need soft, acidic or very warm water.
Use a sand substrate, because acaras dig constantly, taking mouthfuls and re-landscaping the floor, and coarse gravel can scrape their mouths.
Anchor plants to wood and rock or keep them potted, since rooted stems will be dug up sooner or later.
Add driftwood, a cave or two, and a few flat stones that a pair can adopt as spawning sites.
Filter generously, as a meaty-fed 15cm cichlid produces far more waste than a shoal of tetras.
The tank must be fully cycled before the fish arrives, with ammonia and nitrite at zero, and a 25-30% water change every week keeps nitrate down.
Diet
Electric blue acaras are omnivores with a strong lean toward meaty foods.
Build the diet around a quality sinking cichlid pellet, then rotate in frozen or live bloodworm, brine shrimp, krill and chopped earthworm two or three times a week.
A little spirulina or blanched vegetable matter now and then rounds out the menu.
Feed once or twice daily only what is eaten within a couple of minutes.
They are enthusiastic, messy eaters that will beg convincingly, and overfeeding is the fastest route to fouled water in a cichlid tank.
Varied, protein-rich feeding is also what keeps the electric blue shimmer bright rather than washed out.
Health
The underlying blue acara is one of the toughest cichlids in the hobby, but the electric blue line is heavily line-bred and quality varies sharply between sources.
Cheap batches can show bent spines, short gill covers and generally weaker constitutions, so inspect fish before buying and favour a breeder or shop that can say where its stock comes from.
The main acquired problems are ich after stress or chilling, and hole-in-the-head disease, which in this species is strongly tied to old, nitrate-rich water and a monotonous diet, with the Hexamita parasite often implicated.
Watch for pitting around the face and lateral line, faded colour, clamped fins and refusal of food.
Quarantine newcomers for three to four weeks before adding them to the display.
With clean water, varied food and honest tank space, a good-quality fish should sail past its fifth birthday without ever seeing medication.
Temperament
This is the gentle exception among mid-sized cichlids, and that is exactly why it earns a beginner rating where the angelfish does not.
An electric blue acara mostly ignores anything it cannot swallow, and even a pair guarding eggs only firmly pushes other fish away from its corner rather than hunting them down.
It spends its day cruising and bulldozing sand rather than picking fights.
Peaceful does not mean harmless, and the mouth is the measure.
Neon-sized tetras and dwarf shrimp will eventually be eaten, so choose tankmates like black skirt tetras, larger rasboras, bronze corydoras, bristlenose plecos and medium rainbowfish.
Keep one fish, or a proven pair, rather than several loose adults, because two unpaired acaras in a 55-gallon tank may bicker over the same patch of floor.
A good fit for
First-time cichlid keepers with a 4ft tank
Community tanks built around medium-sized fish
Keepers who found rams or discus too fragile
Aquarists wanting easy pair-and-spawn behaviour
Anyone wanting cichlid personality without the temper
Common mistakes to avoid
Tanks under 200L / 55 gallons
Housing with neon-sized fish or dwarf shrimp
Cheap line-bred stock with bent spines or short gill plates
Hole-in-the-head from old water and monotonous food
