Dwarf paradise fish
genus of fishes
The dwarf paradise fish (Parapolynemus verekeri), also known as the streamer threadfin or streamered tasselfish, is a species of ray-finned fish from a family Polynemidae, the threadfins. It is the only species in the genus Parapolynemus and it is found in Australia and New Guinea.
Description
The dwarf paradise fish is the smallest species of threadfin which has an elongated body with a large oblique and turned down mouth. It has two separate dorsal fins, the first of which has 8 spines and the second which has a single spine and 11-14 soft rays while the anal fin has 3 spines and 10 -12 soft rays. The base of the anal fin is shorter than that of the second dorsal fin. The caudal fin has long lobes with the lower usually being the longest; normally it is longer than the distance from the snout to the start of the second dorsal fin. The pectoral fins have 12 to 14 simple rays and are located near the midline of the body and may extend beyond the rear end of the anal fin's base. It has 6 or 7 pectoral filaments; with the fifth filament, the farthest back, being the longest, sometimes reaching past the end of the caudal fin. The pelvic fins reach beyond the anus. There are 50 to 60 (mean 56) scales in the lateral line which ends between the centre of the fork of the caudal fin and its first lower ray.

Why this record matters
“Dwarf paradise fish” is worth following because a concise public description often conceals a longer documentary argument. Here, Dwarf, paradise and fish provides the most credible route into that argument.
Datasets, specimens, observations and peer-reviewed methods provide the appropriate test for the technical claims summarized here. The source revision retrieved here is dated May 21, 2026. The linked authority identifier is Q1927448. None of the 0 selected statements returned an explicit reference.
A general summary may omit uncertainty, sample limits or methodological disagreement that is explicit in the technical record. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
