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.

Disagreements and qualifications

brood-comparison-denominators

20-plus and more than double are unstandardized offspring comparisons. No derived absolute total, fertility, age effect or hatch/survival fraction.

Unresolved contextual/measurement limit; no causal prescription or inferred survival.

esta-adults-not-fry-denominator

Seven surviving original adults are not a fry denominator. Top-ups belong to the main tank, not fry nursery; January/February describe one same-brood trajectory.

Unresolved contextual/measurement limit; no causal prescription or inferred survival.

esta-yolk-timeline

January 9 and a four-day phrase in a January 12 post have uncertain counting/reference. Contextual yolk interpretation cannot establish an exact hatch date.

Unresolved contextual/measurement limit; no causal prescription or inferred survival.

differing_maturity_reports

Reported spawning at 6–7 cm contrasts with profile maturity around 10 cm. Unknown length conventions and cohort ages prevent a fixed maturity threshold.

Unresolved; retain context, no causal synthesis.

different_fry_rearing_approaches

A reported no-supplemental-feed period and water-change losses must not displace another breeder’s successful fed rearing account. Missing water chemistry and controls prevent a causal conclusion.

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.

Reported evidence with source and stock-identity limits; this is not a verified breeding protocol or success probability.

Coverage and gaps

The author reported another clutch, and roughly 20-plus young from younger breeders versus over twice that from established breeders.

Esta bought seven juveniles at 2.5–3 cm roughly two years before discovering her first L397 brood.

On January 9, yolk-bearing fry were moved from the male's tube into an aerated nursery with wood; yolk loss was described four days later.

Powdered catfish food was offered twice daily and leftovers removed. The main tank had three filters and aeration, with 2 L top-ups every two days.

By February 6, the original seven fish were alive; offspring were reportedly 3 cm, with some rehomed.

Ten juveniles obtained in autumn 2013 occupied a wood-and-clay-tube tank with two sponge filters and thin sand. Vegetables supplemented feeding.

Spawning began roughly one year after acquisition, when fish measured 6–7 cm; males guarded cave broods.

At 28°C eggs hatched after six days; yolk absorption and emergence followed nine days later. Reported emerging broods numbered 20–35. Fry first received Artemia, later Cyclops, spirulina tablets and vegetables.

Two males and two females had not spawned during six months despite prior-owner success. Setup included wood, caves, bare bottom and corner matten filtration.

Four initial transfers paled, then recovered colour; twelve more followed. The final update reported molts and all alive, without a denominator.

Introduced White Pearls mostly developed visible saddles; these juveniles had hatched elsewhere.

An earlier White Pearl stock was reportedly predominantly male in the same water.

After males arrived, berried females and one juvenile were reported; the juvenile’s mother and hatch chronology remained unresolved.

Two of three presumed Yellow males later showed saddles; another remained behaviorally male, alongside a reported release.

Three transport survivors all showed saddles.

The keeper reported mostly males, one remaining female and no new visible saddle after her last brood.

Female-biased Yellow stocks were reported on separate occasions; Sakuras reportedly differed.

Selected breeding groups used one male with many females; later saddles were interpreted as sex change, without verification.

Following female losses, two presumed males developed saddles; one became berried. Later, both sexes were reported in breeding stocks.

Sakura-quality offspring were estimated; transient violet coloration preceded one reported death, while others recovered.

A recently acquired Orange Sakura group produced mostly female offspring.

The stock included prior releases, one dropped clutch, a death, juveniles and later berried females; fertilization remained uncertain.

A female-biased purchase later produced numerous juveniles; several females reportedly released and became berried again.

Three shrimp previously treated as males developed visible saddles after selection and a tank reset.

Catalog status is uncertain as Osteogaster schultzei; it records past synonymy with aeneus and possible validity.

Collected-egg fertility was 4/14 and three of four hatchlings reached the described juvenile endpoint; these small-cohort fractions are not predicted success probabilities.

In a later undated-relative comment, the three juveniles were still thriving; another collection of about 30 eggs yielded one hatchling.

By January 2025 the author was placing some eques juveniles in new homes.

A dry-season treatment was not used in this successful attempt, so the log does not support a universal dry-season requirement.

Author describes eggs hatching in about five days and free-swimming roughly two days later, then microworm, pre-soaked crushed flake and fresh brine shrimp.
