Etymology: Paretroplus: Name from the Greek 'para' meaning 'on the side of'; in taxonomy it is commonly used in generic names to express similarity or relatedness; in the present case it would mean 'next to Etroplus' (S.Kullander, pers.comm. 3/11).;  tsimoly: Named for its common name in the Sakalava dialect; Noun in apposition.

Environment / Climate / Range Ecology

Freshwater; benthopelagic; depth range 0 - 2 m (Ref. 40691).   Tropical

Short description Morphology | Morphometrics

Dorsal spines (total): 16; Dorsal soft rays (total): 14; Anal spines: 7-8; Anal soft rays: 12; Vertebrae: 31 - 32. Upper half of head pale beige, a faint narrow interorbital stripe present; snout with distinct pale orange hue in large adults. Lips, lower jaw, lower cheek, branchiostegal membranes and chest bluish grey to dusky purple. Dorsum and flanks pale beige, lightening towards the ventrum. Flanks traversed by 5 or 6 dark grey bars extending from dorsum to the ventrum. Axil of pectoral fin with a dark spot, though not always visible. Vertical and ventral fins smoky beige, broadly edged in bright red. Pectorals uniformly smoky red and the iris of the eye ringed red. Parental individuals with upper half of head, nape and body brilliant golden orange and the vertical bars are intense blue-black. Mature individuals possess a prominent lobed blue lips. Small scales deeply embedded on chest and belly. Accessory parapophyses restricted to the anterior two caudal vertebral centra. With rounded soft anal and dorsal fin extensions passing beyond caudal fin origin. Caudal fin emarginate. Pelvic fins cover the genital papilla when adducted, but do not reach anal fin origin (Ref. 40691).

Biology     Glossary (e.g. epibenthic)

Occurs in flowing water with isolated pools; rocky bottom interspersed with patches of cobble and coarse gravel. A bi-parental substratum spawner. Practices long-term care of its fry; breeding pairs guarding the fry. Stomach contains mainly crushed insects (nymphal odonates and hemipterans) and significant amounts of fibrous plant material (Ref. 40691).

Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5001   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00389 (0.00180 - 0.00842), b=3.12 (2.94 - 3.30), in cm Total Length, based on all LWR estimates for this body shape (Ref. 93245).
Trophic Level (Ref. 69278):  2.8   ±0.32 se; Based on food items.
Resilience (Ref. 69278):  Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153):  Low to moderate vulnerability (32 of 100) .
