Martin.

Are they (the 2 species) from the same shipment ?

From my limited obeservation, smaller Gastromyzon ( G. ctenocephalus / G. scitulus :?: ) have less coloration at their fins than bigger fishes, at caudal fin the smaller fish not just have smaller amount of red/orange color of its caudal, but also have bigger amount of colorless ? of the tip of its ...

Graeme, your fish are Gastromyzon ctenocephalus . Quick ID is (are) the iridescenct blue markings in the dorsal. The similar Gastromyzon scitulus does not have the blue in the dorsal and has a more intricate pattern of black in the caudal. scitulus at top, ctenocephalus at bottom.......... http://w...

Congrats !! LES

Wow !! Its very interesting!! At least, they looks have (pectoral and caudal) fins

This SW01, probably will have truncate snout on bigger fishes?? I have "feeling" if this species have relation with G. ridens and G. crenastus

Perhaps my suspicion is wrong.

I suspected its a desease because its have smaller size than other and I see it not so long after I brought them from lfs.

Its have thinner body, paler color, slower movements, but still eat well??
One already "disappear", but the other still exist til now.

Nice picture Graeme....I like the scattering sand particles! I was looking at one of mine the other day. I've had them since some time in '99 if my memory serves me well. This guy seems to suddenly be showing signs of age and looks to be getting thin in the area above the pectoral fins. Note the so...

Nice fish !! But quite impossible to get them here

Thanks :D Jim, in my experience in fields I never found more than 1 species in the same stream. But from the new paper of Gastromyzon, they found together in the same area. (see the data of examined material, they have the same locality and GPS data) Graeme, here another “mouthworks” in different ta...

"Mouthworks"

Undescribed Gastromyzon from south Kalimantan. Have (very) variable pattern of body !! http://www.loachtank.com/albums/userpics/10100/SK01_0206_01.jpg http://www.loachtank.com/albums/userpics/10100/SK01_0206_02.jpg http://www.loachtank.com/albums/userpics/10100/SK01_0206_05.jpg http://www.loachtank....

This undescribed Gastromyzon have similar coloration of caudal fin with (newly describe) G. crenastus . Probably collected in the same stream with G. scitulus (but perhaps different stream with locality where G. scitulus firstly described) since they found together in the same shipment, not just to ...

Firstly I thought they are G. ctenocephalus but from the new paper (probably) they are G. scitulus . http://www.loachtank.com/albums/userpics/10100/Cte_03.jpg http://www.loachtank.com/albums/userpics/10100/normal_Cte_01%7E0.jpg http://www.loachtank.com/albums/userpics/10100/Cte_05.jpg http://www.loa...
