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

timing_and_advice

11-day versus roughly 34-day clutch observations; one source's three-week discard advice conflicts with its own first hatch.

Different conditions and unknown species prevent harmonization; no discard rule

shr-c02-review-causality

Water change precedes reported eggs but age, acclimation and observation time confound causal attribution.

Qualified temporal progression/context; not a biological contradiction or resolved causal effect.

shr-c02-review-followup

Four egg-carrying females are seller-labelled Taiwan-cross stock, not Mosura; baseline initial no-egg report and later eggs are temporal progression, not a contradiction.

Qualified temporal progression/context; not a biological contradiction or resolved causal effect.

shr-c02-review-nontarget

Ulli Bauer post7 concerns Paracaridina meridionalis; no transfer to CRS/Mosura/Neo or new target claim.

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.

crystal-red-caridina / breedingpersonal-anecdote

Later follow-up reports water changes, then one egg-carrying Taiwan-cross female on February 25 and four on March 1. Mosura reproduction was still awaited. No hatch or recruitment was reported.

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

The keeper reported active angelfish pairs and mixed-age fry, but the acquired-stock contribution and brood outcomes are unresolved.

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

Care reports at a glance

Coverage and gaps

Same-day follow-up said the clutch had hatched successfully.

Later follow-up reports water changes, then one egg-carrying Taiwan-cross female on February 25 and four on March 1. Mosura reproduction was still awaited. No hatch or recruitment was reported.

Another keeper describes over six months without Taiwan-type offspring, followed by improvement after a tank move. Reported brood percentages lack denominators and survival endpoints; the later water values are contextual, not a controlled test.

Red Rili were initially described with a saddled female and a lost male; an October update reports a first brood and about eight shrimplets seen.

Keeper reports losses after mixing stock and few recent losses while using UV. Infection and treatment efficacy were untested interpretations.

Initial divided aquarium lists Red Rili, Painted Fire Red, Crystal Red and Crystal Black stock. The inspected material does not establish CRS/CBS breeding outcomes.

Eight trade-labelled Crystal Reds had not bred during six months of keeping. Later comments add temperature and uncertain sex composition; proposed changes have no outcome follow-up.

A separate keeper reports a few CRS shrimplets shortly after an August purchase, followed by nearly six winter months without breeding, with reproduction described as spring/summer-limited. Constant temperature is asserted; a day-length cause is speculation.

The commenter reports holding CRS with Neos, and separately many classroom-tank babies, but admits the initial hardness advice was for Neos. Offspring taxon and continuity between those tanks are unverified.

The keeper reported active angelfish pairs and mixed-age fry, but the acquired-stock contribution and brood outcomes are unresolved.

The keeper reported two breedings of self-labelled F1 Santa Isabel angels.

Nitika reported 150 White Pearls in a 60 L setup operating about five years. Shared maintenance covers all listed tanks; neither same-cohort longevity nor offspring recruitment is established.

CarrReport offered unsexed Snowball juveniles and described their tap-water readings. Offered packages are inventory, not a measured brood or a survival denominator.

The seller identified orange tankmates as Tangerine Tigers and asserted trouble-free co-breeding; the explicit repeated-berried endpoint concerns the tigers, not a counted Snowball cohort.

kurt9633 reported two deaths among ten recently purchased Snowballs within a couple of days.

The keeper had added KH plus while pH continued falling; the next-day reply names Shrimp Cuisine food and plans fewer chemistry changes, without reporting recovery.

The author reports recording one egg hatching in the main aquarium.

A subsequent nursery transfer reportedly yielded another recorded hatch.

The author usually keeps one or two shrimp with eggs for cleaning; effectiveness was not measured.

The caption describes watching eggs become fry and then striped juveniles, without timing or counts.

Sunwolfy reports inadvertent pygmy fry rearing without targeted direct care; peppered fry are a separate experiment.

metalmudkip reports two rounds of successful hatching followed by progressive fry losses.

Seven stocked fish preceded roughly 23 larger fish plus uncounted fry by September 2021; this is not a survival denominator.

The author reports 50-60% changes once or twice weekly, Bug Bites, microworms and small frozen foods.

Reported nitrate rarely exceeded 10 ppm; method and precision are unspecified.

Cleaning sometimes siphoned fry into the waste bucket; the author inspected removed water for rescue.

In a tank described as Mosura PRL, the keeper counted 12 juveniles: two Mosura-pattern animals and the remainder three-banded.

The keeper reports 350+ CRS juveniles in total and 30 selected Mosura-pattern shrimp.

The source colony reportedly produced two Red Taiwan Bee-type shrimp in different batches; the keeper expressly avoided representing the stock as PRL.

Founders were described as four-band/Hino. After three initial batches, a small Hino subgroup was isolated in a breeder box; Mosura appeared by its second batch, and 30 were subsequently separated into their own tank.
