I started only a few months and surprise that the shops are selling top grades shrimps neo and CRS for SGD $1 to $3 .... think too many breeders and hobbyists in a small place like SG and most are going for boa breeding. The few specialize shops are selling at least SGD$5 to thousands. I saw last night and think few CRS are bearing and the shop I got from has many good grades CRS for SGD$2.50 think they up the prices from 2 and they only use tap water .... think they are purely business sell fast now I know what to look for for CRS but the currents 9 I have when I first pick I have no idea what is SSS grading just pick what I like. Now I know to pick more white with certain patterns and and legs full color. But try not to add more if I can't keep this 9 over 6 months with tap water and new babies.
