Good fit for your tank?

Good fit for

  • Mature planted aquarium setups
  • Intermediate shrimp keepers
  • Peaceful nano aquariums

Think carefully if

  • The aquarium contains shrimp-eating fish
  • The tank is newly cycled
  • Water conditions change frequently

A selectively bred ram with strong blue iridescence and classic dark markings, requiring warm pristine water.

Appearance and Identification

A compact yellow-gold cichlid with bright blue spangling, a black eye bar, a flank spot, red fin accents, and blue patterning in the fins.

German Blue is a captive strain of M. ramirezi rather than a separate species. Quality lines retain normal body shape and clear sex characteristics.

Males are larger with extended anterior dorsal rays. Females usually show a pink or purple abdomen and blue spangling within the black flank spot.

Behaviour and Tankmates

A small lower-level cichlid that is usually peaceful outside breeding but sensitive to poor water quality and social stress.

Keep a compatible pair or a small group in a larger structured aquarium. Forced pairs may fight.

Both parents defend a small spawning territory and may attack bottom-dwelling fish near eggs or fry.

Use peaceful warm-water tank mates that do not dominate food. Shrimplets are prey, and cool-water community fish are unsuitable.

pH
5–7.5
GH
1–10
KH
0–5
TDS
30–180
Stability importance
Critical

The strain thrives at 27 to 30°C in clean soft to moderately mineralised water. Nitrate and organic waste should remain low.

Parameter caveat
Select robust fish from a reputable breeder. Weak mass-produced rams may have poor longevity even under good care.

Feeding

Diet types
Insectivore, Omnivore
Feeding frequency
Daily
Preferred foods
  • Live baby brine shrimpUseful for conditioning adults and feeding juveniles; rinse before use.
  • Daphnia, cyclops, or mosquito larvaeSmall moving prey encourages natural feeding behaviour.
  • Frozen brine shrimp or mysisOffer thawed portions sized for the fish.
  • High-quality cichlid micro-pelletUse as part of a varied diet after the fish accepts prepared food.

An omnivorous micropredator requiring varied small foods and excellent nutrition.

Feed several small meals daily. Avoid relying on flakes alone and do not keep at low temperature to slow metabolism.

Baby foods
  • Newly hatched brine shrimpPrimary food for free-swimming fry; feed small rinsed portions several times daily.
  • MicrowormsUseful supplementary food for small fry near the substrate.
  • Fine powdered fry foodUse sparingly and remove uneaten material.

A biparental open substrate spawner. Eggs are laid on a flat surface or in a shallow pit and guarded by both parents.
