Overview

What is this animal?

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 4.5-6 in 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.

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 4 ft 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 53 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
Rooted plants constantly dug up
Two unpaired adults feuding over territory

Enclosure

Minimum 53 gallons

Fine alone or with company. Singly or as a bonded pair; community-safe with medium fish

Easy care does not mean a small tank, and this is where new keepers most often get it wrong.
Provide at least 53 US gallons (a standard 55-gallon tank qualifies) with a 4 ft footprint for one fish or a pair, because acaras are active swimmers that patrol the whole bottom half of the aquarium.
Keep water at 72-81°F 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 6 in 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.

Care in depth

Diet

Omnivore (cichlid pellets, frozen and live foods)

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

Signs of good health, and the common problems

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.

Is this urgent?

6 warning signs and how fast to act, 3 of them right away

In a fish tank the patient is usually the water. Test before you treat: dosing a healthy tank for a disease it does not have makes things worse.

Go now

Any detectable ammonia or nitrite in a stocked tankLarge water change now with dechlorinated, temperature-matched water. Stop feeding. Test again in 12 hours. Both are directly toxic. How toxic the ammonia reading is depends on pH and temperature, so the same number can be harmless or lethal.

Now

Fish gasping at the surface with fast gill movement, or crowding the filter outflowIncrease surface movement now (gently in a betta or gourami tank, without creating a strong current), then test the water. Either the oxygen has crashed or the gills are being chemically burned. Both are hours-scale problems. Bettas, gouramis and corydoras rise to gulp air as part of normal breathing; the warning is constant gulping, fast gill movement, or the whole group hanging at the top.

Now

Sudden deaths, more than one fish in a dayTest ammonia, nitrite, nitrate and temperature before doing anything else. Do not add medication yet. Multiple simultaneous deaths usually point at the water or the equipment rather than a pathogen, so rule those out first.

Now

Today

Flashing: repeatedly scraping against decor or substrateTest the water, then look closely for parasites. Irritation is either chemical or parasitic; the test tells you which before you medicate.

Today

White salt-grain spots over the body and finsBegin the appropriate treatment today and check the temperature. The parasite's life cycle is temperature-driven, and it multiplies with every cycle you wait.

Today

Soon

Clamped fins, hiding, or refusing food for more than two daysTest the water and review recent changes. Usually the earliest visible sign of a parameter drifting.

A few days

Never add a new fish to a tank that is not fully cycled, and never treat blind. A test kit is cheaper than the fish.

This is general guidance for a healthy adult, not a diagnosis. An exotics vet who knows your animal always overrides it, and the time to find one is before you need one.

Bedding and substrate

3 safe, 4 with a caveat, 2 to avoid

Substrate in an aquarium is a filter as much as a floor. Most of the biology lives in and on it.

Safe

Fine, smooth sandCorrect for corydoras, kuhli loaches, eartheaters such as rams and acaras, and anything else that sifts or burrows. Barbels wear away on sharp gravel.

safe

Smooth, rounded fine gravel (not for loaches or sand-sifting cichlids; sand is better for corydoras)Rinse thoroughly before use. Grain size should be too large to swallow and too small to trap food. Kuhli loaches need sand to burrow into and rams and acaras sift mouthfuls of it; bronze and panda corydoras manage on smooth fine gravel, but sterbai corydoras need sand.

safe

Bare bottom (quarantine and grow-out only)Legitimate for quarantine and grow-out tanks. Easy to clean, but it holds far less biological filtration, and it is no long-term home for burrowing loaches or sand-sifters.

safe

With a caveat

Crushed coral or aragoniteDeliberately raises hardness and pH. Correct for rift-lake cichlids, wrong for soft-water species.

with a caveat

Aquasoil for planted tanksExcellent for plants, but most active soils soften the water and pull pH and KH down for months, and many leach ammonia for the first weeks. Right for soft-water species; wrong for hard-water animals (livebearers, rainbowfish, goldfish, and snails, whose shells erode in soft, acidic water) unless you test GH and KH and remineralise. Cycle around it; do not stock into it.

with a caveat

Very deep sand bedsAnaerobic pockets form below about 2 inches in still sand. Either keep it shallow or keep it stirred.

with a caveat

Painted or coated gravelUsually fine, but coatings chip. Test a handful in a jar for a week first.

with a caveat

Never

Sharp or angular gravel with bottom-dwellersWears down barbels and leads to infection in corydoras and loaches.

never

Anything containing metal, limestone of unknown origin, or shells in a soft-water tankSlowly alters chemistry in ways that are hard to diagnose later.

never
