3.2 – Sexual organization:
Usually one male guard the eggs of several females in his den.

3.3 – Sexing:
There are usually differences between sexes but the extend vary from species to species. In general males are larger than females and in some species have a larger head. Although several variations exist, and vary depending on the species, all Ecsenius share the common Blenniid traits of a greatly reduced first dorsal spine for females, as well as a triangular fleshy lobe encompassing the large urogenital opening, while males have a small opening at the end of the small tube. Males are likely to attain a larger adult size than the females

3.4 - Pairing / Setting Up Broodstock:
Provide basic techniques for establishing breeding pairs in captivity, if known.

3.5 – Courtship:
Describe courtship / signs of impending mating etc, if known.

3.6 – Spawning:
Demersal spawners.
Blennies attract mates near the holes or crevices in which spawning occurs. The females will often initiate courtship, some assuming new coloration for spawning. When the female enters the area the male engages in courtship behavior that can include changing into spawning colors, bobbing the head up and down at the mouth of the cave, and leading the female to the nest by swimming with an undulating motion. One the male may mate with several females. Males of some species apparently move toward an olfactory cue released by other males during spawning. (Thresher, 1984). The male is generally active during spawning, deterring predators, and afterwards guarding the eggs until hatching. Females may occasionally guard the nest as well. One male may mate with several females, brooding all the eggs in the same nest

Don't know where this is supposed to go but I found it ;):

Blennies generally pass through a pelagic, postlarval stage after a short planktonic stage. The young pelagic fishes look different enough from their adult form that they were classified at one time as a separate subfamily. Transformation into the adult form occurs at some time after the postlarvae enter a littoral habitat. (Böhlke and Chaplin, 1994; Moyle and Cech, 2000; Wheeler, 1985)

Ecsenius species hatch into life at roughly 3.5 mm of total length and by the time they reach 12 mm they are nearly identical to adults in color and morphology

Thank you Chelsey !
I´ll update that info soon, if you have any other (as many as you can :D) post here as a reply. We´ll keep the thread "clean" of replies once the info posted is updated to the overview. ;)
Thank you again !
Anderson.

Folks,

I'm not sure but what you call Meiacanthus bundoon is looks like Meiacanthus atrodorsalis to me. Seeing the fish base video of Meiacanthus bundoon I'm positive that I have never seen this fish at any retailer or wholesaler where as Meiacanthus atrodorsalis is rather abundant.
Take care
Peter

Peter
You are correct!
Picture link has been updated.
I linked to Witts thread because the pics are much better than the one on fishbase. Many of the Google Pics are incorrectly labeled, as you already pointed out.

Really, the difference is striking between the two.
Thanks for the heads up.
