FPB / SPECIES EVIDENCE

Careful evidence.
Better fishkeeping.

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

Bounded research coverage
Catalog subjects: October 2, 2026
See current availability

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.

Located evidence

597 matching reports

Located reports and recommendations with attribution.

Care reports at a glance

Uses frozen and gel foods; calling live food best does not establish live-food exposure or comparative efficacy. Read citation and limits

A later brand change is described, without a before/after breeding trial. Read citation and limits

Knackpunkt reported occasional injuries among subordinate L397. Read citation and limits

Disagreements and qualifications

unresolved_nitrogen_fields

Nitrate appears both as 0 and 5 ppm; nitrite absent. Preserve raw labels

Unresolved attribution/identity or dated endpoint; no silent reconciliation, causal inference or survival rate.

absence_followup

Dated non-detection and a reappearance are not interchangeable with deaths; individual continuity is unresolved

Unresolved attribution/identity or dated endpoint; no silent reconciliation, causal inference or survival rate.

individual_birth_linkage

Birth date connects Mohawk Jr. to baseline December 24 family; source stage terminology remains ambiguous

Unresolved attribution/identity or dated endpoint; no silent reconciliation, causal inference or survival rate.

within_thread_breeding_conflict

No-spawn report conflicts with later sibling-spawn pedigree

Unresolved attribution/identity or dated endpoint; no silent reconciliation, causal inference or survival rate.

within_thread_pedigree_conflict

Ms. Orange is described first as daughter of Mohawk Man and later as his granddaughter

Unresolved attribution/identity or dated endpoint; no silent reconciliation, causal inference or survival rate.

within_brood_count_sequence

15, 12 and approximately 17 are dated July brood reports; no silent reconciliation

Unresolved attribution/identity or dated endpoint; no silent reconciliation, causal inference or survival rate.

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.

Suggest a source or report a correction
within_brood_increasing_counts

Approximately 35 then 50, then 20 males plus 15 females have different observation times/stages; no survival denominator

Unresolved attribution/identity or dated endpoint; no silent reconciliation, causal inference or survival rate.

exposure_not_diagnosis

No necropsy or verified diagnosis. Inherited death attributions, images and hypotheses do not establish cause

Unresolved attribution/identity or dated endpoint; no silent reconciliation, causal inference or survival rate.

angelfish_parent_label_ambiguity

Later Blue Blushing male label may correct prior Chocolate male attribution or refer to another pair; no silent resolution

Unresolved attribution/identity or dated endpoint; no silent reconciliation, causal inference or survival rate.

Older author opinions predicted L236 would not be described; the 2025 primary study includes L236 under H. seideli.

Older author opinions predicted L236 would not be described; the 2025 primary study includes L236 under H. seideli.

Retain dated opinion as historical, mark superseded taxonomy context, and keep stock identity unresolved. Do not discard independently useful breeding observations.

A specific 2019 brood was logged at 32°C while a later general adult method describes 28°C.

A specific 2019 brood was logged at 32°C while a later general adult method describes 28°C.

Separate event measurements from later method accounts. Do not average or treat as a proven contradiction for the same event.

Different diets, stages, stocks and evidence types appear.

Do not rank diets as effective using these uncontrolled and non-equivalent accounts.

Storm or parameter-change efficacy is asserted without isolated controls.

Store as author causal opinion, not an established mechanism or required trigger.

January/February document dates can falsely resemble winter breeding evidence.

January/February document dates can falsely resemble winter breeding evidence.

Filter on event date only; unknown remains unknown.

mortality-cause-and-tank-sequence

Entrapment/stress is conjecture, not diagnosis. The later 350 L survivor tank is not the earlier mortality setup; sex is unresolved.

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

no-offspring-not-controlled-failure

No offspring was reported, but duration, sex, breeding intent and controls are unknown. Do not infer tank size caused failure.

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

apistogramma-cacatuoides / breedingpersonal-anecdote

Two females were unseen for two weeks in the separate planted community tank.
