Water is Clean Today

Punggol water is clean today.  It is a pleasure to have clean water and I collected them to replenish my aquarium.  There are lots of small fishes but impossible to net.  So I must buy a trap to catch them.  Most of the time the water is quite dirty or greenish yellow in colour.  When the water is clear, I can see schools of small fishes.  I need to buy a trap to catch them and put them in my aquarium.  I had a white swimming crab in the tank and it is nice to see it moving about.
