what the heck
last night i was looking in the tank w/ a flashlight and i noticed 2 new things. first i saw what i thought was a light brown patch of wierd looking algae....until it moved. i assumeit is some kind of slug. the 2nd is a worm of some sort it was black and white striped and body shape was like a snake (rounded head) rather than a worm.
any iedas what they are and more importantly do i need to get rid of them.
two fish were in a tank, one said to the other "I'll drive you man the guns"
