Ghazanfar,
Thanks.
The water level was quite high when I collect the plants. I only manage to find very few plant. To cut down the risk of losing them all, I planted them in different substrates. All of them are doing well with new leaf growing, and I even have plantlets growing now.
The flowering plant is planted in 30% baked clay:30% garden soil: 30% peat: 10% ADA power sand. To my experience, this combination doesn't have as high survival rate as ADA soil. However, it has the advantage of low cost and hence I tried it again. Obviously it suite this crypt well. In less then two months I have 3 new leafs and a flower.
