Breve descrizione
Chiavi di identificazione | Morfologia | Morfometria
Spine dorsali (totale) : 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).
Body shape (shape guide): elongated.
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).

Males construct a nest made of vegetal material, where females lay the eggs. They guard the eggs until hatching (Ref. 59043).
