 Cat-eLog Data Sheet | |
|---|---|
| Scientific Name | Scleromystax macropterus Regan, 1913 |
| Common Name(s) | Hi Fin Peppered Cory |
| Type Locality | Brazil, Paraná, Paranaguá (25°32'S, 48°36'W) |
| Type Locality Map |  |
| Synonym(s) | Corydoras macropterus |
| Pronunciation | ss KLER oh muss tax - mah CROPP terr uss |
| Etymology | Scleromystax: From the Greek sclero meaning hard and the Latin mystax meaning moustache. This specific epithet refers to its long (makros=long) feather-like fins (pteron=feather, fin). |
| Species Information | |
| Size | 100mm (3.9") SL. Find near, nearer or same sized spp. |
| Identification | A reasonably easy species to ID when adult due to the finnage. Generally more elongate than similarly patterned species. Females may be confused with other species. |
| Sexing | This species' males have (very obvious) longer pectoral and dorsal fins. |
| Habitat Information | |
| Distribution | Coastal rivers from São Paulo to Santa Catarina, Brazil and some upper Paraná River tributaries. Santa Catarina State Rivers (hover or click on these areas to show maps or find other species found there) La Plata , Paraná , Upper Paraná (hover or click on these areas to show maps or find other species found there)Sao Paulo State Rivers (hover or click on these areas to show maps or find other species found there) |
| pH | 5.4 - 7.0 |
| Temperature | 16.0-20.0°C or 60.8-68°F (Show others within this range) |
| Other Parameters | Requires cooler water but can be kept reasonably warm if water is well aerated - this is not recommended for long periods of time. Tolerant of high pH if acclimated gradually. |
| Husbandry Information | |
| Feeding | All prepared foods and live / frozen treats such as bloodworm. |
| Furniture | Smooth pebbles and sand with bogwood and dried beech or oak leaves to leech tannins into the water. Plants can be used but are not necessary. |
| Compatibility | Peaceful community tank inhabitant although it's water requirements (cool blackwater) tend to limit selection somewhat. If the aim is not reproduction then these fish will tolerate higher pH closer but still below neutral. Mature males will fight often inflicting significant damage, keep in a large area or overcrowd them to avoid this. Ratios of males to females does not seem to avert this behaviour. Overcrowded small tanks will require meticulous water management. |
| Breeding | Unreported. |
