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 2.6 in / 6.53 cm).
Water: Freshwater.
Temperature: 68–77°F (range recorded for this species).
pH: 6.2–6.8.
Hardness: 3–10 dGH.
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 35 × 12 in (roughly 21 US gallons); space needed is rated “large tank”.
Water: a fairly wide range, from slightly acidic to slightly alkaline, 68–77 °F, pH 4–7.5, 1–10 dGH.
Behaviour: in a pair; not a community fish.
Difficulty: Moderate (Seriously Fish rating).

Short excerpts from the species profile:

Setup: “Provided adequate cover and structure is available this species is unfussy with regards to décor with ceramic flowerpots, lengths of plastic piping and other artificial materials all useful additions.”
Tankmates: “Captive-raised fish are the recommended choice for the community aquarium.”
Breeding: “Substrate spawner which normally lays its eggs in crevices or cavities among the décor.”

Group care guide

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

Sources 117 119 164 257 258

Diet

Small live and frozen foods (bloodworms, brine shrimp, daphnia) plus quality micro pellets.

Sources 117 119 164 257 258

Social life

Harems or pairs; peaceful with small dither fish.

Sources 117 119 164 257 258

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

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. One male has a harem of several females; 60-120 eggs are laid in caves; male defends all nesting sites.
Water it lives in	Freshwater, 68–77 °F (20–25 °C), pH 6.2–6.8, hardness 3–10 dH.
Climate	Tropical climate.
Behavior to plan for	Breeding: clutch tenders, paternal parental care.

What this means for care

Keep water within its wild range, 68–77 °F.
Parents guard eggs or young, so expect territorial behavior when breeding.

FishBase species summary: Apistogramma steindachneri

Native climate (measured)

Warm-season highs	about 90°F (up to 92°F in the hottest sampled areas)
Cool-season lows	about 71°F (down to 69°F in the coldest sampled areas)
Average temperature	78–81°F across sampled records
Relative humidity	78–80% on average (driest month about 72%)
Rainfall	about 2048 mm a year

Measured at 82 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.

Federal legal snapshot

No federal permit to keep

No federal law singles out this species for private keepers. State and local rules still apply.

State law decides most of it. Each state sets its own permits and bans for exotic, native, venomous and dangerous animals, and cities and counties can be stricter. Find your state agency →

Not covered by the Animal Welfare Act

The Act only covers warm-blooded animals. Reptiles, amphibians, fish and invertebrates have no federal care standards, even at licensed facilities; state and local rules may still apply.
