A strikingly colorful dwarf cichlid native to the Orinoco River basin. Famous for its vibrant blue spangles and peaceful demeanor compared to larger cichlids. They are strictly thermophilic (require high temperatures of 27-30°C / 81-86°F) and thrive in soft, acidic water. As 'earth-eaters' (Mikrogeophagus), they sift sand for food and form monogamous pairs.

Available Varieties
Each variety inherits the species defaults above. Only differences are highlighted.
Standard / German Blue
The classic wild-type coloration featuring vivid blue spangles, a yellow/orange face, a pink belly (in females), and a prominent black lateral spot.
Same care requirements as the base species
Also known as: GBR, Wild Type
Electric Blue
A selectively bred morph exhibiting solid, bright, metallic blue coloration over the entire body. Genetically identical in care requirements but often slightly more sensitive to water quality.
Same care requirements as the base species
Also known as: EBR, Neon Blue Ram
Gold Ram
A xanthic morph lacking dark pigments, resulting in a vibrant yellow-gold body while retaining the signature blue spangles.
Same care requirements as the base species
Also known as: Golden Ram, Xanthic
Long Finned
Features selectively bred extended, flowing fins. Requires gentler flow to prevent exhaustion and snag-free decor to avoid tearing.
Differs in 1 trait from base species
Also known as: Veiltail Ram, Hi-Fin Ram
Balloon Morph
Selectively bred for a compacted, round spine. This mutation drastically alters their swimming physics, compresses internal organs, and requires pristine water. Highly prone to swim bladder issues.

Also known as: Balloon Ram, Short Body
German Blue Ram Care Summary
The German Blue Ram, scientifically known as Mikrogeophagus ramirezi, belongs to the Cichlids - South American family group. Adults reach a maximum size of approximately 6 cm and have a compressed body shape with a moderate growth rate. Classified as mostly peaceful, this species primarily occupies the mid-level and bottom zones of the aquarium and produces a high level of biological waste.
To thrive, the German Blue Ram requires a freshwater only aquarium with a minimum volume of 60 litres and a tank length of at least 60 cm. Water temperature should be maintained between 27°C and 30°C, with a pH range of 5–7 and a general hardness of 1–8 dGH. A low water flow is preferred. To replicate their natural habitat, the tank should include sand (sifters), plants - densely covered, driftwood (digestion/hiding), and leaf litter/blackwater.
German Blue Ram can be kept singly or in a group, making them flexible additions to most setups. Keepers should be aware that this species will defend a territory within the tank. This species is available in 5 varieties: Standard / German Blue, Electric Blue, Gold Ram, Long Finned, and Balloon Morph. Each may differ slightly in size, temperament, or care needs, so it is worth checking the specific requirements of the variety you plan to keep.

Kribensis
Pelvicachromis pulcher
A vibrant and highly popular dwarf cichlid native to the slow-moving rivers of West Africa. Unlike Rift Lake African cichlids, they prefer soft, slightly acidic water and densely planted tanks. They are generally peaceful in a community tank but become fiercely territorial and aggressive when breeding, often digging pits in the substrate and claiming the bottom zone. They are cave spawners and require hiding spots like driftwood or coconut shells.
Texas Cichlid
Herichthys cyanoguttatus
The Texas Cichlid is the only cichlid species native to the United States. Known for their striking pearlescent blue/green spots and extreme territorial behavior, they require large tanks and robust filtration. They are notorious for rearranging aquariums, digging massive pits, and destroying live plants.
Dwarf Gourami
Trichogaster lalius
A peaceful to semi-aggressive labyrinth fish native to South Asia. Famous for their brilliant metallic blue and red stripes. While generally suitable for community tanks, males are territorial toward each other and similar-looking fish. They are sensitive to water quality and prone to Iridovirus if stressed. Requires access to the surface to breathe.
African Butterfly Cichlid
Anomalochromis thomasi
A peaceful, colorful dwarf cichlid from West Africa. Unlike many cichlids, it is plant-safe and generally suitable for community tanks. It is famous in the hobby as an efficient biological control for pest snails.
Cardinal Tetra
Paracheirodon axelrodi
A stunning schooling fish native to the upper Orinoco and Rio Negro basins in South America. Famous for its brilliant iridescent blue line and a vivid red stripe that extends the full length of its body (distinguishing it from the Neon Tetra). They are strictly schooling fish that thrive in warm, acidic blackwater environments.
Blue Dolphin (Hap)
Cyrtocara moorii
A striking blue Lake Malawi Haplochromine cichlid famous for the pronounced nuchal hump (head bump) that develops in mature adults, resembling a dolphin. They are benthopelagic micro-predators that naturally follow digging fish in the wild to catch stirred-up morsels. While relatively peaceful for an African Cichlid, they grow very large and require extensive swimming space and hard, alkaline water.
