Info

Blenniella caudolineata is widespread in tropical waters and prefers shallow reef zones and tidal pools with large algae zones, which form the fish's main source of food. Although invertebrates hidden in the algae are also eaten when feeding, this does not seem to cause any problems.

As can be clearly seen in the pair photos, the males can reach up to 8.2 cm SL, while the females remain significantly smaller at a maximum of 6.8 cm SL.
Both males and females have a low posterior crest.
This species exhibits a high degree of sexual dimorphism in color pattern.
The females have numerous longitudinal stripes on the sides and black spots on the fins, while the males have dark spots and small blue dots on the sides.

Etymology:
“Caudo” in the German language often refers to anatomical directions, especially “caudal.” ‘Caudal’ means “toward the tail” or “toward the feet” and describes a direction away from the head.
“Lineata” is derived from the Latin word “linea,” which means “line” or “line,” so ‘lineata’ means “striped,” “lined,” or “lined.”

Synonyms:

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!
