Three-striped Dwarf Cichlid

About

Every other Apistogramma in this catalogue lives on the equator. This one does not. A. trifasciata runs from the rio Guaporé south through Paraguay to the middle Paraná in Argentina, and that latitude is the whole personality of the fish: Seriously Fish gives it 20–25 °C where it gives the panda 24–28, Maidenhead's care sheet opens the band at 18 °C, and AquaInfo describes the wild cycle plainly — summer water up to 28 °C, winter down to about 18, with the warming afterwards acting as the spawning trigger. Nothing else here comes with a winter built in. The name is a promise about markings, and it takes a moment to see all three. The obvious one is the lateral stripe running head to tail. What the other two are depends on who you read: AquaInfo puts the second along the back at the base of the dorsal fin and the third slanting down from the pectoral fin to the anal, adding that the upper and lower ones are not always showing, while the diagnosis Seriously Fish prints has the second running from behind the eye to the rear edge of the gill cover and only agrees with AquaInfo about the third. The male's flag is his dorsal: pointed membranes on the first four to six hard rays, drawn out into long spikes over an emerald-to-steel-blue body with a yellow head. Two trade colour forms exist, sold as 'blue' and 'red'. He is also the reason the tank has to be long — a mature male holds a territory and drives off other males, while several females inside it each hold a cave, so the barriers between those caves matter more than the litre count. There is one more reason this species is worth knowing. When Römer and Beisenherz worked out that temperature, not conception, settles the sex of Apistogramma fry, A. trifasciata is the species their abstract names for the timing: the sex is determined 'within a sensitive period of about 30 to at least 40 days after spawning'. That window is documented for this fish and inferred for the rest of the genus. On size, take the numbers as a range rather than a fact: 5.5 cm standard length for a male on Seriously Fish, 6 cm maximum at Maidenhead, 5–7 cm total length for adult males on AquaInfo, and only 3.8 cm SL in FishBase's museum record. We gate at 6.5 cm. Expect two to three years, not five.

Care

One male to two or three females, in a tank of about 80 cm and 80 litres — the length is his territory, the caves are theirs, and each female needs a spawning site she cannot see her neighbour's from. Fine sand, wood, coconut shells or a flowerpot on its side, dried leaf litter and dim light; Microsorum, Taxiphyllum and Cryptocoryne grow in that light and the fish leave them alone. Aim for pH 5.5–6.5 in soft water under about 8 °dGH at 23–26 °C. This is the one Apistogramma here that is genuinely relaxed about temperature, and Seriously Fish says it is 'less fussy than some congeners and can withstand slightly soft, neutral water, with aquarium-bred specimens more adaptable still' — but that tolerance stops at nitrate, which it will not forgive. Small, frequent water changes, gentle flow, a mature filter, and a tight-fitting cover because these fish jump. Corydoras, hatchetfish, pencilfish and small tetras are the tankmates the sources name; other Apistogramma are not. When the female leads fry out of the cave she becomes the most dangerous fish in the tank, and in a short tank the male is the one who has to go. The common mistake is treating it as a delicate blackwater fish and heating it to 28 °C all year: it is a subtropical animal that will take a cooler winter, and warming it afterwards is what starts the season.

Diet

Carnivorous micropredator on bottom invertebrates, though AquaInfo calls the wild diet omnivorous — small invertebrates, plant matter and detritus. Frozen and live Artemia, Daphnia, Moina and bloodworm are the core, with a small sinking pellet rather than flake for the dry portion.

Telling males from females

What works for this species, most reliable first.

• Extended finsStrong · from about 8 months, and later in a suppressed male

  On many cichlids and killifish the male's dorsal and anal fins draw out into trailing points as he matures, while the female's stay rounded.

• VentingA hint only · only on a mature fish, easiest when she is in breeding condition

  The method breeders use when the answer has to be right. Hold the fish upside down in a wet hand or soft net and look at the two openings ahead of the anal fin. The forward one is the anus; the one behind it is what you are reading.

• Adult sizeA hint only · only across animals of the same age

  In many cichlids, catfish and loaches one sex simply grows larger — usually the male, though there are well-known reversals.

Frequently asked questions

What tank size does a Three-striped Dwarf Cichlid need?

A Three-striped Dwarf Cichlid needs an aquarium of at least 80 litres (21.1 US gallons) with a footprint at least 80 cm (31.5 in) long — for this species, swimming length matters as much as raw volume.

What water parameters does a Three-striped Dwarf Cichlid need?

Three-striped Dwarf Cichlid does best at 18–28 °C (64.4–82.4 °F), pH 5–7 and a general hardness of 1–10 °dGH.

What group size does a Three-striped Dwarf Cichlid need?

Three-striped Dwarf Cichlid is a social species — keep a group of at least 3 so natural behaviour emerges and stress stays low.

Is the Three-striped Dwarf Cichlid suitable for beginners?

Three-striped Dwarf Cichlid sits in the middle of the difficulty scale — manageable for a careful beginner who has done the reading, but it has specific needs worth researching first.
