Trimma cavicapum Allen & Munday, 1995
Excerpt from oceansciencefoundation.org:
A new pygmy species, Trimma cavicapum, is reported from St. Francois Atoll in the Alphonse Group of the outer islands of the Seychelles in the Indian Ocean. The new species was initially thought by the first author to be Trimma dalerocheila, a species with an essentially red ground coloration and white/light blue lines on the head,
has pale blue lines on the head and was described from the Seychelles.
Two specimens obtained by the junior authors for COI analysis show that the new species differs considerably in the DNA sequence of this gene, and closer examination of the morphology and color pattern revealed further differences.
The live color pattern of this species is diagnostic, with a solid yellow or light brown body with three light blue stripes (one medial, two bilateral) on the head on a yellow to strong pink/red background.
It occurs in pairs or small groups and inhabits crevices and/or caves on steeply sloping reefs below 20 m and has recently been photographed on Astove Island.
Trimma cavicapum lives associated with reefs and inhabits rubble slopes at the foot of vertical cliffs. The dwarf goby usually hovers vertically or at an angle, several centimeters above the bottom. These dwarf gobies should only be associated with small fish, otherwise they quickly become food for large fish. They are also very shy. They are really interesting to watch if only calm fish are chosen as roommates.
Please only keep them in pairs or groups. This goby would be an ideal animal for a nano tank due to its need to swim and its behavior.
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".
