thanks Standoyo...
You can call me 'khong'....

Is there any website to read on takashi amano riccia planting trick? I am not sure where can I find hair grass in Penang..... maybe I seen them before but don't realise that their name is hairgrass.....

Now I just hope my remaining riccia will growth to 'wild' again before my next replantting.... I am now collecting the losen riccia every day and nite and re-tie them into a new nursary on the rock.... Mytank is fulled of small rock now(about the size of 50cents coint)... each of them is a nursary of riccia....
