Brachiosaurus Blenny
Just wanted some opinions on this fish. Male or female?

I've never seen this fish before and I think it's COOL! :thumbsup:
But reading on Live Aquaria about it I believe it to be a male just from their description. overview The Brachiosaurus Blenny is an exciting new addition to the aquarium trade, generating buzz among hobbyists. It is easy to see how this blenny received its common name as the male Brachiosaurus Blenny sports a pronounced fleshy crest that gives it a distinct dinosaurian appearance. If that wasn't enough to capture your imagination, the male Brachiosaurus Blenny also sports very exotic-looking finnage (most notable is the sail-like dorsal fin) that enhances the "prehistoric" appearance of this buzz-worthy blenny. http://www.liveaquaria.com/images/ca...rus-blenny.jpg http://www.liveaquaria.com/product/p...63&pcatid=3263 |
Found a book about that genus in PDF form:
Revision of the blenniid fish genus Omobranchus: with descriptions of three new species and notes on other species of the tribe Omobranchini Didn't read much of it but seems to be quite informative. "Females: Similar to males except: head background usually not as dark; dark bands and markings on head more apparent; pale spaces between dark bands slightly broader; body background paler; body bands less distinct; usually 4th and occasionally 5th horizontal series of intense, dark spots present on body; spots in somewhat less distinctly arranged rows; fins less distinctly pigmented; dorsal fin often only with dark dusky blotches along base above dorsal ends of body bands. ... COMPARISONS.—Omobranchus anolius is unique in Omobranchus in having the posterior segmented dorsal-fin rays of larger males long and filamentous. The 15th ray, for instance, may attain a length of up to 31.9% SL, more than in any other species of Omobranchus. In O. ferox and aurosplendidus the 15th ray may attain a length of 22-24% SL, but none of the rays become filamentous or much exserted beyond the margin of the interradial membrane (the dorsal-fin spines of male aurosplendidus do, however, become long and filamentous). In O. anolius there are several series of small, dark spots that appear to be superimposed on the color pattern of the body. Omobranchus elegans, aurosplendidus and, to a much lesser extent, meniscus also have a similar spotting, but the spots are smaller, more numerous, and more randomly distributed in these three species. Some specimens of O. fasciolatus appear to have a similar spotting, but the spots are not so intensely dark and do not appear to overlie other features of the color pattern." |
Thanks for the information Throewer! And DK you are right the LFS confirmed with me their mix up. Now I have to return a male to get the female so they don't battle for territory.

Let us know when they got babies :D

Picture is a bit fuzzy and not at an ideal angle, but it looks like the females don't have the Brachiosaurus head bump. In that case sexing these guys should be quite simple.

very very cool little fish, i have 3 males and 6 females. they are very social with each other
and with me. they have the cutest little face and mouth, they are comb toothed. they are known as the brachiosaurus blenny. in australia we call them oyster blenny and if you do a google search you should see that the pictures of the fish are recognizable in both the US and AUSTRALIA. this is because they share the same habitat, both the coast of australia and the coast of mexico. there are other species that look identical too, in other parts of the world (france and germany's coast). there version is the Salaria pavo or peacock blenny. it's basically the same thing but with different colouration. amazing how nature works. they are super interactive. watching them graze on algae is the cutest. the way they munch and look up at you and pause. then continue munching ahahaha. they follow your finger around. when they are hungry they will beg for food. i'm pretty sure they can be trained to eat from your hand as well, they are super interactive. i've got a picture of one when i took him out of the water to move to another tank while cleaning his holding tank. i have him in my hand and he's like a blob of blue jelly with a smiley face. ahahahahaha anyways if anyone can provide details of their reproductive nature that would be awesome! |
