hi, im new to this site and i was wondering if anyone could help me out with my little problem. my fish tank is maybe 4 months old. this is my second tank but my first non gold fish tank. i've one casualty. (my oscar) im usually good about maintaining my tank. but the fish i have are a little more work than my goldfish were. (least i think so) theres always something with these guys. First it was ich, and now i think there are parasites in there. as i looked in the tank this morning thinking its water change time, i see this floating worm squiggling away. I THINK ITS A PARASITE!!!! and if not, im sure my fish have parasites because of there behavior. What should i do besides medicate and how do i rid my tank of these ugly little buggers?
