Trimma irinae Winterbottom, 2014
Trimma irinae, (Pisces; Gobioidei) a new species of gobiid fish from Milne Bay Province, Papua New Guinea
RICHARD WINTERBOTTOM
Abstract
A new species of Trimma, T. irinae, is described from 65 m off Lawadi, Milne Bay Province, Papua New Guinea.
This colourful new species has red-orange spots on the head and anterior trunk, with a yellow to orange body posteriorly. The first dorsal fin has two dark basal spots, and the elongated section of the second dorsal spine is bright white to pale blue in life.
There are 8–9 scales in the predorsal midline, usually cycloid scales present along the upper border of the opercle in up to three horizontal rows, no cheek scales, and the middle 9–11 rays of the pectoral fin are branched. The fifth pelvic fin ray branches once dichotomously and is 52–64% the length of the fourth ray, and the basal membrane connecting the inner margins of the fifth pelvic fins rays is less than 15% the length of the fifth ray.

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".
