how to clear slug

[beetlejuice403]

Thanks Beetlejuice , I have promptly removed it when I saw it, and it swims really fast!! Just wondering if "found one means more will come"?? Will check tank again.

Umm... you find them more active at night when lights are off... how did you notice this? You went to peek on them with a torch light? Hehehe
Thank you.

Checking to see if they got go sleep after 'lights off' or up to some hanky panky...

No lah, on few occassion, woke up in the middle of the night & decided to visit my tanks... So saw alot of these planaria crawling & swimming in the tank very freely when I on the tanks' lights immediately...
