Info
The small cleaner goby Elacatinus pridisi is found over rocky reefs and calcareous algae beds around Trinidade Island, about 1150 KM from Brazil, in the southwestern Atlantic Ocean.
During the day, and for most of the goby's life, it can be seen engaged in cleaning activities, with clients ranging from large carnivores such as the Caribbean reef shark (Carcharhinus perezi (Poey)) to small planktivores such as the small damselfish Chromis multilineata (Guichenot, ), 1853.
Unlike other cleaner fishes, however, Elacatinus pridisi coexists not only with corals, such as the stony coral Montastrea cavernosa, but also with sponges.
Brief description of the color pattern:
A bright yellow stripe extends from the eye to the base of the fins, becoming narrower near the eye (more uniform in juveniles).
On the snout there is a bright yellow oval spot.
A dark, broad longitudinal stripe extends to the lower abdomen and the base of the anal fin; all fin rays, except the caudal fin, are black or dark in color.
Etymology: the species name "pridisi" is used in honor of the First District of the Brazilian Navy (Primeiro Distrito Naval, Marinha do Brasil - "PRIDIS"), in recognition of the impeccable logistical support during the authors' excursions to the type locality.
Distribution:
Elacatinus pridisi is currently known only from Trindade Island, a volcanic formation of the Trindade-Martin Vazim oceanic island complex in southeastern Brazil, and is likely to be an endemic 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!
