Yesterday during our guppy gathering @ Ikea, we saw some rummy nose @ East Aqua Studio of Pet Safari (the side tenant). Still juvenile fishes less than 1" long selling at around RM3/pc (I forgotten liao yesterday really blur blur) but they have quite alot about 30-40 fishes cramped inside the small tank. Red coloration starting to appear nia not sure whether it'll spread to like the one in your picture.....
