So here are the Sri Lankan rasboras post-revision. /smile.gif" style="vertical-align:middle" emoid=":)" border="0" alt="smile.gif" />

The one previously considered to be a form of R. daniconius is now R. dandia Valenciennes 1844. The paper says it's the most common freshwater fish on Sri Lanka so I guess this is the fish we see in the trade as R. wilpita. The main difference between this and the others is that the lower jaw symphysial knob and premaxillary lateral process aren't prominent (vs. prominent):

This one is R. wilpita, restricted to just a handful of localities:

Then two new ones. R. armitagei:

...and R. naggsi:

This is what we have labelled as R. wilpita in the Knowledge Base (Mark's fish). R. dandia?

Finally, R. microcephalus which was previously thought to be R. caverii, which is now a synonym of R. dandia... /wacko.gif" style="vertical-align:middle" emoid=":wacko:" border="0" alt="wacko.gif" />

Has Rasbora vaterifloris been reclassified then?

Used to have a group of these - very attractive fish when they'd coloured up.

Mature, sensible signature required for responsible position. Good prospects for the right candidate. Apply within.

Yup Mark R. vaterifloris has been in its own genus (Rasboroides) for over 15 years only the literature hasn't caught up. /smile.gif" style="vertical-align:middle" emoid=":)" border="0" alt="smile.gif" />

I have spent most of today trying to get a good look at them Matt, any other time they dont race around like complete nut jobs /laugh.gif" style="vertical-align:middle" emoid="Laugh" border="0" alt="laugh.gif" />

The up shot is going off those pics I have both wilpita and dandia /ohmy.gif" style="vertical-align:middle" emoid=":o" border="0" alt="ohmy.gif" />

when they are side by side the differences are distinguishable, I did comment when I got my second batch that they looked different from what I already had. I will try and get some comparison pics later in the week when I am doing water changes, I will try an maybe net a couple out (no mean feet in the 7ft tank /laugh.gif" style="vertical-align:middle" emoid="Laugh" border="0" alt="laugh.gif" /> )
