It's very difficult to generalise about SEA crypts..... there are species which are unique to Indochina, Malaya, Thailand, Borneo, Sumatra, New Guinea, Philippines etc... as well as a few (e.g. C. ciliata) which straddle the geographical regions. SEA crypts (except for a few like C. balansae, C. pontiderifolia, C. cordata) tend to be much more testy than the Sri Lankan/Indian species.... being found in very sheltered, cool, little-changed habitats.
Do look up Jan Bastmeijer's Crypt Pages (check google) for detailed data on the species.
Many SEA species like C. nurii and C. griffithi are very difficult to cultivate in aquariums...... I suspect that apart from an acidic substrate, shady spot and low nitrate levels, the plants like good water circulation and COOL temperatures (below 28C) to thrive. Most crypt biotopes I have seen have very cool, flowing waters.
You will have to hunt around for these species in LFS though..... I know Lam Hong (AMK Ave 4) has C. ponti regularly.... while Bioplast (System Control & Engineering) has griffithi and cordata on occasion..... you can try Teo's Farm for nurii and others if he has fresh stock..
But growing these crypts emmersed is a better bet for their survival..... use a covered plastic tray (Far East Flora has propagators for less than $10) to create a humid environment, and plant them in mixed plain gravel/peaty soil and keep the substrate wet. If they thrive, you can always use the new plants for the aquarium.
