Environment: milieu / climate zone / depth range / distribution range
Freshwater; benthopelagic. Subtropical; 39°N - 38°N, 21°E - 23°E
Europe: Greece (lower Sperchios drainage). In Appendix III of the Bern Convention (protected fauna).
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 4.5 cm SL male/unsexed; (Ref. 59043); max. reported age: 1.50 years (Ref. 59043)
(total): 2 - 6. Distinguished from congeners in Europe by possessing the following unique characters: dorsal fin with 2-6 spines; and pelvic girdle absent or very reduced. Differs further from other members of the genus by having the following combination of characters: body pale olive with blackish mottling; and absence of keel on side of caudal peduncle (Ref. 59043).
Adults inhabit spring-fed streams and ponds, with temperature rarely rising above 20° C and dense vegetation. Feed on small aquatic invertebrates and fish larvae. Spawn in May-June. Males build a nest and guard the eggs until hatching. Threatened due to habitat alteration and water abstraction. Attain a maximum size up to about 4.5 cm SL (Ref. 59043).
Life cycle and mating behavior
Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae
Males construct a nest made of vegetal material, where females lay the eggs. They guard the eggs until hatching (Ref. 59043).
