Apistogramma cacatuoides ‘Super Red’

Cockatoo Dwarf Cichlid — Complete Species Guide

What’s in the Name?

The genus name Apistogramma comes from the Greek apisto (ἄπιστος, ‘unreliable’ or ‘uncertain’) and gramma (γράμμα, ‘line’ or ‘marking’) — literally ‘unreliable line’, referring to the variable lateral line markings that make species identification notoriously difficult. The species name cacatuoides means ‘resembling a cockatoo’, from the Spanish cacatúa (cockatoo) plus Greek -oides (resembling). This perfectly describes the male’s spectacular dorsal fin — tall, spiky rays that fan out like a cockatoo’s crest. The species was first scientifically described by Hoedeman in 1951 from specimens collected in the Ucayali River basin in Peru. The ‘Super Red’ variant we stock is a line-bred form developed by Southeast Asian breeders, selected over decades for maximum red pigmentation across all fins.

Colour Varieties: Decoding the “Red” System

Walk into any aquarium shop and you’ll see Cockatoo Cichlids labelled “Double Red,” “Triple Red,” “Super Red,” or “Orange Flash.” These aren’t random marketing terms — they describe exactly where the red-and-black patterning appears on the fins:

Super Red morph: red/black patterning covers all four fin groups — Dorsal, Caudal, Anal, and Pelvic fins.

Colour morph comparison — from left: Double Red (2 fins), Triple Red (3 fins), Super Red (4 fins), Orange Flash (solid orange, no black).

One thing worth knowing: none of these colour forms exist in the wild. Wild A. cacatuoides show subtle blues, yellows, and coppers depending on collection locality. Every “Red” and “Orange” variant is the result of decades of selective breeding. The ‘Super Red’ we stock represents the peak of that work — maximum red coverage across all fins, with characteristic black streaking that gives each fish a unique pattern.

Male vs. Female: Spot the Difference

Male ♂ (left, ~8 cm) vs Female ♀ (right, ~5 cm) — dramatic size, colour, and fin shape differences.

Few freshwater fish show sexual dimorphism as dramatic as A. cacatuoides. Once you know what to look for, sexing them is straightforward — even in juveniles.

Water Parameters: What They Need and Why

A. cacatuoides is often called the most adaptable Apistogramma species. That’s true — but “adaptable” doesn’t mean “anything goes.”

pH: 6.0–7.0. They’ll survive in neutral water, but you’ll see the best colour, behaviour, and breeding success in slightly acidic conditions. Sydney tap water typically runs around 7.0–7.5, which is workable — a small amount of driftwood or Indian almond leaves brings pH down naturally.

Temperature: 24–28 °C. Aim for 26 °C as a baseline. Bump to 28 °C if you’re trying to trigger breeding. Below 24 °C they become sluggish and susceptible to illness.

Hardness: 1–10 dGH. Soft water is strongly preferred. For breeding, the lower end (1–5 dGH) significantly improves egg fertility and hatch rates. Sydney water at around 1–3 dGH is actually ideal for this species straight from the tap.

Filtration. Gentle flow. These fish come from near-stagnant forest pools. A sponge filter is perfect — biological filtration without stressful currents. If you’re using a hang-on-back or canister, baffle the outflow.

Tank Setup: Building Their World

A pair needs a minimum of 75 litres. Running a harem (one male, two to three females — the ideal ratio)? Step up to 120+ litres so each female can establish her own territory.

Substrate — fine sand, full stop. Apistogrammas sift sand through their gills while foraging. It’s a natural behaviour you’ll observe daily. Gravel frustrates this instinct. Pool filter sand or aquarium-specific sand in natural beige works perfectly.

Caves — non-negotiable. Females need enclosed spaces to spawn and feel secure. Coconut shell halves (with a small entrance hole) are the classic choice. Ceramic breeding caves work too. Provide at least one cave per female, plus one extra. Position them at least 30 cm apart — each cave becomes the centre of a female’s territory.

Plants — the more the better. Dense planting breaks sight lines, reducing aggression and giving fish escape routes. Java fern, Anubias, Cryptocorynes, and floating plants like Amazon frogbit all work well. The floating cover also dims the light — something these forest-stream fish prefer.

Driftwood. Provides hiding spots, leaches tannins that soften water, and creates the tangled root structure these fish navigate in the wild. Spider wood or Malaysian driftwood are good choices.

A well-planted community tank — fine sand, driftwood, low-light plants, and floating cover. This type of setup suits most dwarf cichlid species.

Diet & Feeding

In the wild, A. cacatuoides hunt insect larvae, micro-crustaceans, and whatever tiny invertebrates they can sift from the substrate. In your tank, replicate that variety:

Staple (3–4×/week): High-quality micro pellets or crushed flakes for dwarf cichlids.
Frozen (2–3×/week): Bloodworms, brine shrimp, daphnia — rotate between them.
Live (1–2×/week): Baby brine shrimp, microworms, grindal worms — nothing triggers breeding behaviour like live food.

Feed small amounts twice daily rather than one large feed. Their stomachs are tiny. If food is still on the substrate after two minutes, you’ve given too much.

Breeding: The Cave Drama

This is where A. cacatuoides genuinely earns the word “fascinating.” Breeding this species isn’t hard — it’s one of the easiest Apistogrammas to spawn — but watching it unfold is extraordinary.

Act 1 — Courtship

When ready to spawn, the female’s colour shifts from pale yellow-brown to intense, saturated yellow with bold black markings — lateral stripe, cheek patches, and ventral bars all darken dramatically. She becomes a completely different-looking fish overnight. This “brood dress” is her signal to the male. She’ll approach his territory with exaggerated body shimmies and present herself near a cave entrance.

Act 2 — Spawning

The female enters the cave and deposits eggs on the ceiling — usually 40–80 salmon-pink eggs in a tight cluster. The male briefly enters to fertilise them, then leaves. From this moment, the cave belongs entirely to the female.

Act 3 — The Guard

For 3–4 days, the female rarely leaves the cave. She fans the eggs constantly with her pectoral fins, removes any fungused eggs, and aggressively blocks the entrance against everything — including the male. Her yellow brood dress intensifies further during this phase.

Act 4 — Free-Swimming Fry

After 3–4 days the eggs hatch into wriggling larvae. Another 4–5 days and the fry become free-swimming — a cloud of tiny fish following their mother around the tank like ducklings. She shepherds them, signals danger with body twitches that scatter the fry into cover, and maintains her fierce defensive posture for 3–4 weeks until they’re large enough to be independent.

First foods for fry: Infusoria or commercial liquid fry food for the first few days, then freshly hatched baby brine shrimp (BBS) as soon as they’re big enough. BBS is the single most important food for growing healthy Apistogramma fry.

A dedicated breeding tank — coconut caves, sponge filter, Indian almond leaves, and tannin-stained water. Simple but effective.

Community Tank Mates

A. cacatuoides are community-safe — with the right companions. The golden rule: choose species that occupy different water layers so territories don’t overlap.

Tank zones — A. cacatuoides occupy the bottom substrate layer, while tetras school mid-water and hatchetfish stay near the surface.

In a 120 L+ tank, a single male with 2–3 females plus a school of 10–12 tetras and 6 Corydoras makes a beautifully balanced community. We stock all of these species in our Eastwood store.
