FPB / SPECIES EVIDENCE

Careful evidence.
Better fishkeeping.

Read what keepers observed, what authors recommend, and where the evidence leaves questions open.

Keeper reports are attributed experiences. They do not establish species identity, independent replication, biological causes or a guaranteed breeding method. Trade labels and missing measurements remain unresolved.

Splettstößer uses N. palmata var. White, recalling the older cf. zhangjiajiensis label. He describes approximately 28-day egg carrying and fully formed hatchlings, and warns that fish eat young. This identifies his reported trade lineage, not every animal sold as Snowball. Read citation and limits

Coverage and gaps

This is a growing index of selected public sources. Shared authors, copied pages and overlapping cohorts do not count as independent corroboration. Date, unit, taxon, denominator and endpoint gaps remain visible in the reports.

Human-origin judgments rely on attribution and source evidence; no reliable AI detector is claimed. This library republishes original limited summaries and attribution, with no publisher full text or media.

Coverage and gaps

Fifteen Black/Blue Rili arrived cold and were acclimated from reported GH14 to GH21; several died within days, including a berried female. Eight earlier Bloody Mary appeared well. Tank age, shipment stress, hardness change and uncertain parasite claims prevent attributing losses to one cause.

Kaminski reports White Pearl living and breeding for over a year under his measured conditions. He labels them N. cf. zhangjiajiensis var. white. Introductory generic ranges are attributed to retailer pages and must not be counted as his measured trial.

Eight White Pearl produced no observed young over five months, despite saddle and mating-swim observations. The report cannot distinguish absent fertilization, egg loss, predation or undetected recruitment; reply suggestions are not demonstrated causes.

Splettstößer uses N. palmata var. White, recalling the older cf. zhangjiajiensis label. He describes approximately 28-day egg carrying and fully formed hatchlings, and warns that fish eat young. This identifies his reported trade lineage, not every animal sold as Snowball.

He retracts any implication that 10 °C is suitable indefinitely, distinguishing brief winter dips from routine care. He recommends 20–26 °C, while mentioning a seasonal 18–26 °C cycle; these are experienced opinion, not controlled tolerance limits.

AquaTom72 saw White Pearl and blue-tiger young about four weeks after removing moss balls and planning water changes. He treated this as proof moss balls were harmful, but concurrent changes and normal brood timing prevent that causal conclusion.

The palmata wild-form entry reports fully developed young, about forty eggs, and first egg carrying near three months/2 cm. KAQ conditions are pH7, GH8, 25 °C and 50 L. These are wild-form analogy, not an exact Snowball-line trial.

About 55 fry remained at thirty days.

About 20 fry remained at fifty-nine days.

Routine changes were 50% twice monthly.

Report gives approximately 60 eggs or fry, stage combined.

First spawn followed canister installation within one week.

Fry received cucumber and algae wafers on alternating days.

Hardness was unknown; tap water remained unaltered.

Hatch dated 22 January 2022.

Reported average nitrate was 10 ppm.

Tank-raised parents were one male and four females.

Reported pH was 8.

Spawn dated 17 January 2022.

Free swimming dated 29 January 2022.

Tank listed as 20 gallons, 30 × 12 × 12.

Average was 80°F; narrative range 78–80°F.

Original tank already had floating plants and biofilm-coated furnishings.

Keeper supplied zucchini and algae wafers continuously.

At least seven albino fry had left the father's cave.

Replies suggest grazing surfaces or microbes might explain planted-tank benefits.

Fry were moved from bare substrate to planted sand/gravel tanks.

Previous fry died when approximately 1–1.5 inches long.

Water changes were 50% every other day.

Unnoticed April 2024 L519 spawning produced perhaps ten babies.
