Care at a glance
Species-specific aquarium care
- Tank: At least 24 in long and 12 in front to back for one adult (adults commonly reach about 1.3 in / 3.3 cm).
- Water: Freshwater.
- Temperature: 77–82°F (range recorded for this species).
- Layout: Uses both the bottom and open water: give open swimming space plus cover near the substrate.
Calculated from this species' own FishBase record: tank size from its typical adult length and swimming zone, water values from its recorded ranges. The group guide below fills in general care.
Care guide
Species care notes
- Tank: a base of at least 18 × 15 in (roughly 13 US gallons); space needed is rated “modest tank”.
- Water: soft, acidic water, 81–86 °F, pH 4.5–5.8, 0–1 dGH.
- Behaviour: temperament territorial.
- Difficulty: Moderate (Seriously Fish rating).
Short excerpts from the species profile:
- Setup: “Taeniacara candidi require a densely planted tank with plenty of hiding places (these can be covered by bits of driftwood, bogwood, mopani wood or clay/plastic garden pots).”
- Diet: “Taeniacara may not accept dried food.”
- Tankmates: “Taeniacara candidi are said to be one of the most aggressive dwarf cichlids around.”
- Breeding: “Some reports indicate that breeding Taeniacara candidi is extremely difficult.”

South American dwarf cichlids
Applies to most species in this group. Habitat: Soft, acidic, leaf-littered streams. Individual species can differ, so compare with the species numbers above and the linked sources.
Housing & setup
- Use species-specific water chemistry and tank base dimensions: M. ramirezi has a source minimum base of 60 × 30 cm; M. altispinosus has 90 × 45 cm. Provide fine sand for these substrate-sifting species.
- Very sensitive to nitrate and water swings; mature, stable tanks are best.
Climate & lighting
Starting point only: Replace the merged genus range with separately sourced species water temperatures. Check the species-specific values for this animal where shown.
| Water | 76–84°F |
Diet
- Small live and frozen foods (bloodworms, brine shrimp, daphnia) plus quality micro pellets.
Social life
- Harems or pairs; peaceful with small dither fish.
Health watch
- Use mature, stable aquaria. Warm-water M. ramirezi has a source maintenance range of 27–30 °C (81–86 °F), whereas M. altispinosus has 24–28 °C (75–82 °F).
Understanding the animal
About this animal
About this animal
This species is considered a dwarf cichlid in which reaches a length of 5 centimetres (2.0 in) TL. This species can also be found in the aquarium trade, but requires very soft, acidic water and is known for being unexpectedly aggressive for a fish its size; a male will usually kill any other males in a tank shorter than 4 feet in length.

In the wild

From this species’ own FishBase record (habitat, bottom type, water and breeding data), not its family. Good care copies these conditions.1
| Where it lives | Lives in freshwater. Uses both the bottom and open water. |
| Water it lives in | Freshwater, 77–82 °F (25–28 °C), pH 5.5, hardness 5 dH. |
| Climate | Tropical climate. |
| Behavior to plan for | Breeding: clutch tenders, maternal parental care. |
What this means for care
- Keep water within its wild range, 77–82 °F.
- Parents guard eggs or young, so expect territorial behavior when breeding.
Native climate (measured)
Native climate (measured)
| Warm-season highs | about 90°F (up to 91°F in the hottest sampled areas) |
| Cool-season lows | about 71°F (down to 70°F in the coldest sampled areas) |
| Average temperature | 79–81°F across sampled records |
| Relative humidity | 82–85% on average (driest month about 79%) |
| Rainfall | about 2194 mm a year |
Measured at 50 wild occurrence records sampled against WorldClim 2.1 climate data (1970–2000 averages). Air conditions in the range are ecological context, not enclosure settings: microhabitats such as burrows, leaf litter or basking rocks can be cooler, warmer or more humid.
