Info
Very special thanks for the first two photos of Enneapterygius hemimelas to Dr. Vincent Chalias, he has taken the photos at Bali, Indonesia.
The threefin blenny Enneapterygius hemimelas is widespread throughout the Pacific Ocean.
Adults are found in a variety of reef habitats, especially on reef slabs in tide pools and surf-blown reef margins.
This species also occurs in intertidal areas and is usually associated with coral rock outcrops and coral reef lagoons.
Eggs are hemispherical and covered with numerous sticky filaments that anchor them in the algae at nesting sites.
Larvae are planktonic and are found primarily in shallow, nearshore waters.
Males have a dark underside of the head and their bodies darken abruptly toward the rear, occasionally with alternating broad dark and light bands.
Adults can be identified by the greenish tail, and the color usually extends well onto the body.
Adult males have two broad black bands below the third dorsal fin attachment and caudal peduncle, with the two bands joined ventrally; the posterior portion of the anal fin is black in adult males of the threefin blenny, the caudal fin attachment is white, and pectoral and pelvic fins and body are orange in adult males.
Females are much less color conspicuous, see photo, they are well adapted to their habitat with their body pattern.

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".
