Amazing photographs, among the better ones 've seen. What kind of camera did you take this with exactly if I may ask?
I have an old Kodak DC260 which now has a busted flash and broken USB connector so I bought a $99 Fuji A 201 till I can get something better. I'm thinking of an old Nikon 950 or if I have good fortune one of the new Canon SLR's which I'd buy used off ebay.
Were you able to find any Crytpcoryne species there? Apparnly C. pontiderifolia is common there. It looks like a radican sword, big heart shaped leaves on long stems.

just a Canon G5 digicam with a stack of close-up filters from +4 to +9. the trick is that I uses a SpeedLite 550EX mounted OVER the tank and triggered by wireless. The only way to get good pictures is to provide plenty of light, and flash is good in that it is very similar to daylight in temperature.
I seriously would not suggest that you use film. shooting these buggers, who consistently and recalcitrantly refuses to cooperate by staying still, is pretty much hit and miss so the only practical, not to mention economical way, to do it is with a digicam or DSLR. My G5 which is about 18 months old, is now approaching 40,000 shots!
Cryptocoryne? the only species native to Singapore is C. griffithii and a natural hybrid C. × timahensis.

Nice shrimp! If the larvae don't need to desend to brackish/saltwater to survive then they must be a Neocaradina sp Most Caradina need to desend to the sea to undergo a successful molting process and then return upriver to take up a benthic lifestyle.
BTW I know some characters in Singapore who regularily raid the reservoir for escaped plecos and flowerhorns. As there are crocodiles where they go fishing I believe they are 'Kiashi':-D

can't be, there are many Caridina sp. that are purely freshwater, e.g.Caridina temasek and the two other known Caridina species in the Central Catchment.
is it true that large eggs means the larvae stage is spend inside the egg case rather than free swimming?

Depending on the size of the eggs and the gestation time is usually a good indicator of the development and ability of the fry to immediately takeup a benthic lifestyle.

Hi Ed,
When it comes to larvae needing brackish water/saltwater or not the Caridina/Neocaridina distinction is not helpful. There was a misconception among hobbyists for a long time that only the Neocaridina reproduce in complete freshwater. This misconception still survives in some circles. If you look at my "shrimp varieties" page you will see that there are a lot of Caridina that produce large eggs and "mini-shrimp" hatch out of those large eggs instead of floating larvae. There are actually only a very limited number of Neocaridina out there and they are all closely related, the most famous example being the "Red Cherry." All other algae eating shrimp coming from Asia, including the Bee Shrimp and Crystal Reds, are Caridina.
