Source-derived summary

The hard-palate catfish (Brustiarius solidus), also known as the hard-plate catfish, is a species of sea catfish in the family Ariidae. It was described by Albert William Herre in 1935, originally under the genus Arius. It is a tropical freshwater fish which is found in Indonesia and Papua New Guinea. It reaches a maximum standard length of 60 cm (24 in), with both sexes more commonly reaching an SL of 35 cm (14 in). It reaches a maximum weight of 1.8 kg (4.0 lb).

The hard-palate catfish feeds on shrimp in the genus Macrobrachium, algae in the genus Salvinia, insects and nymphs, Ophieleotris aporos, leeches, earthworms, and detritus. Adults spawn year-round, laying eggs in quantities ranging from 8-85, which are incubated orally.

Editorial analysis

Why this record matters

“Hard-palate catfish” is worth following because a concise public description often conceals a longer documentary argument. Here, Hard-palate, catfish and species provides the most credible route into that argument.

Evidence profile

The date and method of observation matter as much as the stated conclusion, especially where classification or consensus has changed. The source revision retrieved here is dated Mar 22, 2021. The linked authority identifier is Q3757202. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1935.

Critical limits

Scientific names, classifications and consensus can change while older terminology persists in catalogues and historical literature. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.

How to read it

Check terminology, classification and the date of the cited evidence. Scientific names and technical consensus can change while older records retain historical value.
