Schistura sp. 'danang'

I got these chaps in a few weeks back (some of you may remember there was a rather pretty goby contaminant in with them) and thought I'd share a few pictures:
Sorry for the reflection at the front of this one, I included it so that you could see the interlocking pattern on the dorsal surface:
They can change colour quite dramatically. This is kind of what they look like when escaping from scuffles with one another and taking time out on the bogwood (I had to lighten this pic though). Interestingly, when this happens, the others on the sand do not bother them:
My reputable supplier claims this is a new species, but I'm open to any ID suggestions. The common name they have been assigned is Vietnamese Banded Sumo Loach.

Actually, very nice
Looks like something different.
How is their size/aggression level? The word "Sumo" makes one worry...

Schistura spp. of these color and pattern can be found all over Thailand. I'm not saying that your fish are not new or that it is of the same species,as we found in Thailand, but it is extreamly difficult to tell them apart or get the exact ID of species from each location. I ,for one, doesn't have a clue.

Yes, they are quite snappy with one another, but as mentioned above, when a fish has had enough it tends to retreat to a piece of bogwood and darkens down and then it appears to be left alone by the aggressors.
They are 2.5-3" long and quite heavy bodied.

I've seen these mixed in with some
Schistura spilota way back when i first found mine. Similar head shape but size and pattern separated them. I think these are a peaceful species given their size.
Lovely additions Emma! I might purchase a few.

I am pretty sure these are S. carbonaria.

Schistura carbonaria? Cool!
I wonder if Mark or Steve has seen these in the The Freshwater Fishes of Central Vietnam book.

Yes they are in the book Graeme
Distinguished from the other species of the genus in the studied area in having 6-10 regular dark bars on the body, darker predorsal and dorsal parts of body, short and broad processus dentiforms, short barbels and complete lateral line. From syntopic Schistura huongensis it differs with shorter barbels: the inner rostral barbels not reaching corner of mouth (vs. reaching), outer ones reaching only the base of maxillary barbel (vs. reaching the centre of eye), and maxillary barbels reaching posterior margin of eye (vs. reaching beyond the posterior margin of eye).
Known from Central Vietnam only, coastal rivers, Central Vietnam from the river Ve (Quang Ngai province) to the river Quang Tri (Quang Tri province).
Found in medium sized rivers and streams in riffles with rocks and gravel substrate.
SL max: 72mm
Some specimens of Schistura carbonaria collected in the basin of the Thu Bon, Tra Khuc and Ve have more pointed processus dentiformis.

Superb!
I think a new loach to the species index is wise!

We need to be nice to Mr Thoene now......
I'll also try for some more pics this week (in the photo tank maybe) when I am getting more of the new
Cobitis (?) sp.

Hello All
I looked at carbonaria when I was looking through the Serov book, but I passed it over because Emma's pictures dont appear to show the dark spot at the base of the first 2/3 dorsal rays and the red spot after it, and the body base colour and bar colour seeming different. It may be down to the lighting and mood of Emma's fishes being different to the one in the Serov book.

Here's another pic I didn't realise I had taken - might be a bit clearer:
