German Blue Ram

Mikrogeophagus ramirezi

Animalia›Chordata›Actinopterygii›Cichlidae

📍 Orinoco Basin, Venezuela

The German blue ram is a strikingly coloured dwarf cichlid demanding pristine water quality and warm, soft, acidic conditions. It forms monogamous pairs and will defend a small territory during breeding. Sensitive to poor water quality and temperature fluctuations, making regular water changes critical.

Care Guide

Diet

German Blue Rams are omnivores requiring a varied diet of high-quality micro pellets as a staple, supplemented 2-3 times weekly with live or frozen foods such as bloodworms, brine shrimp, and daphnia. Feed small portions once daily, only what they can consume in 2-3 minutes, as they are bottom feeders with small mouths.

Behavior

German Blue Rams are peaceful, territorial cichlids that spend most time on the substrate foraging and exploring. They form monogamous pairs and will defend a small breeding territory, but remain non-aggressive toward other peaceful community fish outside of spawning periods. They are most active during dawn and dusk.

Breeding

Breeding in captivity is moderately difficult and requires pristine water conditions, soft acidic water (pH 5.5–6.5), and temperatures at 28–30°C. Pairs will lay eggs on flat surfaces and exhibit strong parental care, but fry survival depends on excellent water quality and frequent small water changes. Breeding pairs may become aggressive toward tank mates during this period.

Tank Mates

Otocinclus

Peaceful bottom dweller with identical water parameter requirements; will not compete for territory

excellent

Ember Tetra

Small, peaceful schooling fish that occupy mid-water column and prefer similar warm, soft water conditions

excellent

Red Cherry Shrimp

Peaceful invertebrate that shares preference for soft, acidic water; may be preyed upon if very small

good

Bolivian Ram

Similar dwarf cichlid that may compete for territory; only suitable in larger tanks with adequate space and hiding areas

caution

Common Diseases

Ich (Ichthyophthirius multifiliis)

Symptoms

White spots on body and fins, rapid breathing, lethargy, rubbing against surfaces

Treatment

Raise temperature gradually to 30–31°C, perform daily 25% water changes, use aquarium salt (1 tsp per 5 gallons) or ich-specific medication; treat for 7–10 days

Fin Rot

Symptoms

Frayed or deteriorating fin edges, discoloration, lethargy

Treatment

Perform immediate 50% water change, improve water quality with frequent changes, use antibiotic medication if severe; ensure pristine conditions as this species is sensitive to poor water quality

Hole-in-the-Head Disease (HITH)

Symptoms

Small holes or pits developing on head and lateral line, loss of appetite

Treatment

Perform 50% water changes every 2–3 days, improve diet with varied foods including vitamin-enriched options, use metronidazole if bacterial; often linked to poor water quality or nutritional deficiency

Stress-Related Illness

Symptoms

Faded coloration, hiding, loss of appetite, rapid breathing

Treatment

Maintain stable water parameters (temperature 27–30°C, pH 5.5–7.0), reduce tank disturbances, provide adequate hiding spaces, perform regular water changes; this species is highly sensitive to fluctuations
