Compiled by Aquairi from published sources · Published · Updated
Overview
Yellow Goldback Shrimp (Neocaridina davidi var. 'Yellow Goldback') is a freshwater dwarf shrimp of the family Atyidae, listed in the Aquairi knowledge base as a beginner-level species. Yellow Neocaridina with a distinct golden-yellow stripe running along the back from head to tail.
Taxonomy
- Family: Atyidae
- Genus: Neocaridina
- Scientific name: Neocaridina davidi var. 'Yellow Goldback'
- Common synonyms: Yellow Backline, Goldenback
Habitat
The wild ancestor Neocaridina davidi originates from Taiwan and adjacent eastern China, where it inhabits lowland streams, ditches and ponds with abundant submerged vegetation and leaf litter. Colour forms are selectively bred from the dark wild type and propagated in commercial culture worldwide. The Aquairi knowledge base records this entry from: Taiwan (selectively bred).
Tank requirements
- Minimum tank volume: 20 L (5.3 US gal)
- Adult size: 2-3 cm
- Temperature: 20-28 °C (68-82 °F)
- pH: 6.5-8
- GH: 6-14 °dGH
- KH: 2-8 °dKH
- Lifespan: 1-2 years
Diet
A grazing detritivore. In the aquarium the shrimp continuously feeds on biofilm, soft algae, decaying plant matter and dropped food. A small daily ration of a shrimp-formulated sinking pellet, occasional blanched spinach or zucchini and rare protein wafers keep the colony in good condition without polluting the water.
Compatibility
Peaceful and best kept in a colony of ten or more in a stable, well-cycled, planted aquarium. Suitable tank mates listed in the Aquairi knowledge base: Otocinclus, Endler's Livebearer, Nerite Snail. Should be kept away from: Cichlids, Crayfish.
Breeding
Reproduces in fresh water without a planktonic larval stage. Mature females develop ripe ovaries visible as a yellow or olive "saddle" on the back; after a successful moult they are fertilised by males and carry the fertilised eggs under the pleopods for roughly three to four weeks before juveniles hatch as miniature fully-formed shrimp. Stable parameters and absence of predation are the main success factors.
Yellow Goldback Shrimp Breeding Guide
Overview
Yellow Goldback is a yellow morph of Neocaridina davidi distinguished by a golden-yellow stripe running along the back from head to tail. The breeding biology matches all Neocaridina: easy reproduction with a sexed pair and stable water, external egg-carrying by the female, and direct development of shrimplets with no larval stage.
Sexing
Females are larger, more strongly colored, and have a broad curved tail for holding eggs; males are smaller and paler. The maturing egg saddle behind the head can be partly masked by the dorsal stripe, but it remains visible before eggs pass to the swimmerets.
Conditioning
Hold parameters in the species range: temperature about 22-26 °C and pH near 6.5-8 with stable hardness. As detritivores the shrimp graze biofilm, algae and detritus and eat their molts, so a mature planted tank covers most feeding needs with light supplementation.
Breeding Setup
A species-only tank with gentle filtration and moss best supports the colony. Both the yellow body and the dorsal stripe are recessive selectively bred traits. Crossing different Neocaridina davidi morphs reverts the young to brown wild-type, so the Goldback line must be kept apart from other color morphs to preserve the pattern.
Spawning & Berried Females
Mating follows a molt, with pheromone signaling and external fertilization as eggs move to the pleopods. A berried female carries roughly 20-30 eggs and fans them under the tail for about two to three weeks until hatching. Steady parameters limit the risk of a dropped clutch.
Shrimplet Care
Shrimplets hatch at about 1 mm as miniature adults and graze biofilm immediately. They mature in roughly two to three months and live one to two years. Holding the Goldback look requires selecting young that show both strong yellow and a clean dorsal stripe, removing plainer or weakly colored individuals.
Common Challenges
The dorsal stripe is variable, so some young show it weakly and are culled from the breeding line. The main risks are mixing with other morphs, which collapses color toward wild-type, and unstable water or copper exposure, which stress berried females and harm eggs.
