These are on Glazer's list this week - Schismatogobius ampluvinculus.

Blurb: "We received for the first time now this cute goby from Taiwan. Especially the juveniles look extreme pretty due to their contrasting black-and-white coloration. One of the generic characteristics of Schismatogobius is the fact that they have an individual coloration: there are not even two specimens with the exact same coloration. Adults of Schismatogobius are restricted to fresh water. Here they live usually in larger groups in shallow parts of running water bodies. When disturbed they bury themselves very fast by wriggling moves. The species S. ampluvinculus is known to inhabit pebbly ground.

Very nice, and just look at the size of the mouths on the adults!

Cool-looking, no? I guess the smaller fish in the last pic is a female?

Certainly looks that way /smile.gif" style="vertical-align:middle" emoid=":)" border="0" alt="smile.gif" /> I am pretty certain that I read in one of the papers that some males of goby species (really cannot remember which) use their mouths for territorial disputes and that the dentition is also geared towards that....but, don't quote me on it, I would really need to look into it further. It certainly seems, in the species above at least, that the male has the biggest mouth.

Update on this - after keeping these for a few days the people at Glaser have discovered that the black and white colouration isn't juvenile patterning. The next two photos allegedly show the same specimen:

If this is true I want some even more now. /tongue.gif" style="vertical-align:middle" emoid=":p" border="0" alt="tongue.gif" />

Great fish, I manage to get 2 a year or so back, different species poss S. marmoratus they were both male going by mouth size and as bully mentioned they do use their mouths in territorial disputes, its really impressive they can open almost 180 degrees the ones species I have have a bright yellow/orange mouth. Unfortunatly one died soon after purchasing it, but the other is still going strong, one of my favourite fish really interesting character although he does spent 99% of the time buried in the sand.

Some more pictures with Japanese text. Looks like the same species? Look at the gape on the fish at the bottom! /blink.gif" style="vertical-align:middle" emoid=":blink:" border="0" alt="blink.gif" />

They do seem very similar. Great shot of the mouth!
