Diagnostic Description
provided by Fishbase
Anterior oculoscapular, preopercular, and sometimes posterior oculoscapular, canals present; body squamation complete on caudal peduncle and along at least lateral midline to axil. Males with 4-5 major vertical bars.
Life Cycle
provided by Fishbase
Spawns up to 4 portions of eggs (Ref. 59043).
Migration
provided by Fishbase
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): 7; Dorsal soft rays (total): 7 - 8; Analspines: 1; Analsoft rays: 7 - 9; Vertebrae: 31 - 32
Trophic Strategy
provided by Fishbase
Inhabits fresh to hypersaline waters (to 55 ppt) of lakes, estuaries and lagoons, in shallow areas with much weed. Feeds on small crustaceans and chironomid larvae.

Biology
provided by Fishbase
Inhabit fresh to hyper-saline waters (to 55 ppt) of lakes, estuaries and lagoons, in shallow areas with much weed. Feed on small crustaceans and chironomid larvae (Ref.12215); larvae of the mussel Dreissena polymorpha (Ref. 59043). Lives less than 2 years. Spawns after first winter. Eggs are attached to the roof of a cavity under stones, plant material or shells and are defended by male. Postlarvae are pelagic. (Ref.59043).

Caucasian dwarf goby
provided by wikipedia EN
Knipowitschia caucasica, the Caucasian dwarf goby, is a species of goby native to marine, fresh and brackish waters along the coasts of the Black Sea, the Sea of Azov, the Caspian Sea and the Aegean Sea and to the Haliacmon drainage of Greece. It inhabits shallow waters (0 to 2 metres (0.0 to 6.6 ft)) with plentiful weed growth where it can find its prey consisting of small crustaceans, the larvae of chironomids and the larvae of the mussel Dreissena polymorpha. Spawning takes place after their first winter with the eggs being deposited onto the roof of a cavity formed by rocks, shells or plant materials. The male will remain to defend the eggs. This species can reach a length of 5 centimetres (2.0 in) TL[2]
