Freckled Dwarfgoby, Eviota lentiginosa Greenfield & Randall 2017
Eviota lentiginosa, a new dwarfgoby from Norfolk Island, Australia (Teleostei: Gobiidae)
A new endemic species of dwarfgoby, Eviota lentiginosa n. sp., is described from Norfolk Island, an isolated island 1400 km east of the Australian mainland. The new species is distinguished by having the cephalic sensory- canal pore system with only the IT pore lacking (Pattern 2); a at, rounded, plate-like male urogenital papilla; the dorsal/anal n-ray formula 8/8; all pectoral- n rays apparently unbranched; the fth pelvic- n ray absent; a dark spot on the lower half of the pectoral- n base; and the body color yellow with a peppering of small brown melanophores in life. It is the sixth species of Eviota known from Norfolk Island.
Inhabits rocky and coral reefs.
The gobiid genus Eviota, known as dwarfgobies, is a very speciose genus with 113 valid described species to date, not including this new species (Green eld 2017).

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!
The term "reef safe" is often used in marine aquaristics, especially when buying a new species people often ask if the new animal is "reef safe".
What exactly does reef safe mean?
To answer this question, you can ask target-oriented questions and inquire in forums, clubs, dealers and with aquarist friends:
- Are there already experiences and keeping reports that assure that the new animal can live in other suitably equipped aquariums without ever having caused problems?
- Is there any experience of invertebrates (crustaceans, hermits, mussels, snails) or corals being attacked by other inhabitants such as fish of the same or a different species?
- Is any information known or expected about a possible change in dietary habits, e.g., from a plant-based diet to a meat-based diet?
- Do the desired animals leave the reef structure "alone", do they constantly change it (boring starfish, digger gobies, parrotfish, triggerfish) and thus disturb or displace other co-inhabitants?
- do new animals tend to get diseases repeatedly and very quickly and can they be treated?
- Do known peaceful animals change their character in the course of their life and become aggressive?
- Can the death of a new animal possibly even lead to the death of the rest of the stock through poisoning (possible with some species of sea cucumbers)?
- Last but not least the keeper of the animals has to be included in the "reef safety", there are actively poisonous, passively poisonous animals, animals that have dangerous biting or stinging weapons, animals with extremely strong nettle poisons, these have to be (er)known and a plan of action should have been made in advance in case of an attack on the aquarist (e.g. telephone numbers of the poison control center, the treating doctor, the tropical institute etc.).
If all questions are evaluated positively in the sense of the animal(s) and the keeper, then one can assume a "reef safety".
