Flag Tailed Glass Perchlet

Resembles A. urotaenia, but differs in having large eye, and a gently-rounded snout. Eye diameter over 30% and interorbital width over 20% of head length. Cheek scales in 2 rows. Attains 8 cm TL.

Aontheca Infestation. Parasitic infestations (protozoa, worms, etc.)

Amphidromous. Refers to fishes that regularly migrate between freshwater and the sea (in both directions), but not for the purpose of breeding, as in anadromous and catadromous species. Sub-division of diadromous. Migrations should be cyclical and predictable and cover more than 100 km.Characteristic elements in amphidromy are: reproduction in fresh water, passage to sea by newly hatched larvae, a period of feeding and growing at sea usually a few months long, return to fresh water of well-grown juveniles, a further period of feeding and growing in fresh water, followed by reproduction there (Ref. 82692).

Dorsal spines (total): 8; Dorsal soft rays (total): 9 - 10; Analspines: 3; Analsoft rays: 9 - 10

Inhabits clear, flowing creeks, usually within 20 kilometers of the sea (Ref. 44894). Commonly found in brackish waters and river mouths. Occurs near mangroves, stagnant and running freshwater (Ref. 7300) and coastal areas (Ref. 45255). Feeds on zooplankton and benthic animals (Ref. 11889).

Inhabits clear, flowing creeks, usually within 20 kilometers of the sea (Ref. 44894). Commonly found in brackish waters and river mouths. Occurs near mangroves, stagnant and running freshwater (Ref. 7300) and coastal areas (Ref. 45255). This species has a marine larval stage, judging from its broad distribution. One of the best viewing areas is at the Freshwater creek picnic ground in Cairns, where individuals frequently aggregate along the vegetated stream margin (Ref. 44894).
