The ember tetra is a small fish native to the lower Amazon basin in central and western Brazil where it inhabits minor tributaries, backwaters and oxbow lakes rather than main river channels. The ember tetra grows to an adult size of .79 inches long. Adult males are more intensely colored than females, especially when in spawning condition. Females are noticeably rounder bodied than males.
The ember tetra should be maintained in an aquarium of 10 gallons or larger. It thrives in densely planted aquariums with gentle water flow, floating plants, and leaf litter (CS706). A soft, sandy substrate (CS6631) and driftwood pieces will round out the aquarium nicely and provide enough cover to make these small fish comfortable.
The ember tetra prefers a temperature of 68°F to 83°F, a pH of 5.0 to 7.0, and a hardness of 1 to 10°H.
The ember tetra is typically a very peaceful and fish and suitable for a small community aquarium. It will fare especially well in a heavily planted aquarium. Good tank mates include ornamental shrimp, and other small fish such as pygmy cories, otocinclus, hatchet fish, small rasbora, and other small tetra species. Ember tetras also make good dither fish for dwarf cichlids, such as Apistogrammas.
Ember tetras are micro predators feeding on tiny invertebrates and other zooplankton in nature and should be fed small meaty foods including live black worms, frozen cyclops (SF1001), frozen baby brine shrimp (SF1003), high quality flakes (AL165), and freeze dried CALA-fin (AL1802). For maximum color, growth, and health these fish will look their best when given probiotics (AL169) in addition to a balanced diet.
