Results for “snout”

This species has the characteristic overhanging snout possessed by all three members of the genus. It has chisel-shaped teeth which are designed for grazing algae off rocks. These physical adaptations allow it to graze algae from rocks situated in very shallow water which other species cannot reach. The position of the mouth allows the fish to remain parallel to the rock surfaces, thus enabling it to cope with the turbulence in these areas. L. fuelleborni exists in many different colour forms in...

This species has the characteristic overhanging snout possessed by all three members of the genus. It also has chisel-shaped teeth which are designed for scraping algae off rocks. These physical adaptations give it a competitive advantage, as they allow it to graze from rocks situated in very shallow water which other species cannot reach. The position of the mouth allows the fish to remain parallel to the rock surfaces, thus enabling it to cope with the turbulence in these areas. L. trewava...

N. binotatus is distinguished from similar-looking congeners such as N. longistriatus and N. ornatus by its unique body patterning consisting very simply of two dark stripes, one running along the dorsal surface and the other from the tip of the snout, through the eye and along the flank. There are usually 1-3 small, vertically-orientated spots extending above the lateral stripe between the pectoral-fin and dorsal fins. These are su...

This species is normally imported alongside a smaller-growing, near-identical congener currently listed as R. cf. nantaiensis with both traded as R. candidianus. They can be separated by snout length, which is noticeably longer in R. candidianus, and adult size with R. cf. nantaiensis reaching just 50-55 mm. R. candidianus can be distinguished from other congeners by a combination of cha...

This fish is normally imported alongside the congener R. candidianus and is actually the commoner of the two in the aquarium trade. It looks very similar to R. candidianus but does not grow as large and possesses a more rounded snout. Most specimens also have spot-like markings on the sides of the head which has led to them being identified as R. nantaiensis, but the fish do no...
