Very special thanks for the first photo of Ptereleotris randalli to one of the describing scientists, Dr. Floeter.
Ptereleotris randalli is found over sandy bottoms close to reefs.
The Brazilian dartfish is common in sand patches as small as 10 cm; also in calcareous algae areas.
It is found in the aquarium trade where it is collected under the name Opistognathus leitoso (Gasparini and Floeter 2001).
The population is declining fast in some areas of the Brazilian coast (mainly off the States of Espirito Santo and Bahia) due to commercial exploration of the calcareous algae banks.
This species hovers over its burrow feeding on plankton and dives headfirst in to the burrow when threatened. Found usually over sandy bottom close to reefs, but also common over sand patches as small as 10 cm in diameter, enclosed by rocky areas or in calcareous algae (Lithothamnion sp.) banks.
Classification: Biota > Animalia (Kingdom) > Chordata (Phylum) > Vertebrata (Subphylum) > Gnathostomata (Superclass) > Pisces (Superclass) > Actinopterygii (Class) > Perciformes (Order) > Gobioidei (Suborder) > Microdesmidae (Family) > Ptereleotrinae (Subfamily) > Ptereleotris (Genus) > Ptereleotris randalli (Species)
Jumping guard
A jumping guard prevents (nocturnal) fish from jumping out.
Wrasses, blennies, hawkfishs and gobies jump out of an unprotected tank in fright if their night rest is disturbed, unfortunately these jumpers are found dried up in the morning on carpets, glass edges or later behind the tank.

A small night light also helps, as it provides the fish with a means of orientation in the dark!
