Description
Melanocharacidium cf. dispilomma is a rare, bottom-dweling South Americn ground tetra belonging to the family Crenuchida . Growing to a maximum size of about 5 cm (2 inches), it is distinguished by its ability to change color drastically, peaceful demeanor, and specialized perching behavior in fast-flowing waters.
Key Characteristics & Biology
- Size: Reaches roughly 5 cm (2 inches) in total length.
- Appearance: The “cf.” designation indicates it closely compares to Melanocharacidium dispilomma but may represent a distinct regional variant or separate species within a wider species complex (often slimmer in body shape depending on the specific river basin or import origin like Brazil or Peru). Males feature noticeably prolonged pectoral and ventral fin rays.
- Coloration: Capable of shifting intensity rapidly, moving from nearly black to a dark horizontal stripe paired with a reflective light band.
Aquarium Care & Behavior
- Social Behavior: Completely peaceful and indifferent toward other fish species and live plants. They enjoy the company of their own kind and will playfully interact or tease each other without causing physical fin damage.
- Habitat Preferences: Being a stream-dwelling/rapid-inhabiting fish, they appreciate moderate to good water movement, clean filtration, and overhead cover such as driftwood arches or broad-leaved plants that mimic natural shaded perches.
- Diet: Omnivorous; they readily accept standard, appropriately sized micro-pellets, frozen foods, and live foods.
