Biologia     Glossario (es. epibenthic)

Found in ditches, canals, ponds. Occurs at the surface in habitats with dense growth of aquatic plants. Feeds on small crustaceans, insects and protozoans (Ref. 12693). Non-annual breeder. Is very difficult to maintain in aquarium (Ref. 27139). Not seen in markets (Ref. 12693).

Estimates based on models

Phylogenetic diversity index (Fonte Biblio. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00479 (0.00189 - 0.01213), b=3.13 (2.91 - 3.35), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Fonte Biblio. 69278):  3.4   ±0.45 se; based on food items.
Resilienza (Fonte Biblio. 120179):  Basso, tempo minimo di raddoppiamento della popolazione 4.5 - 14 anni (Assuming fec < 100).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100). 🛈
Price category (Ref. 80766):   Unknown.
