well everything's been fine..until...well i'm thinkin i have some parasites or somethin..haven't had any other probs....so i tried Copersafe medication. I don't know if it worked or not. Also I got a new Pleco...just a normal 2 dolla one. So in 2 days I've lost 3 fish!!! My Platy that I've had since I got the tank and has always thrived no matter what. and my 2 cory cats...now...I think that the cory cats tail seemed a little nibbled. Could my pleco have killed them. I don't know what it is. HELP ME!!! I'm Dyin here I feel sad!!!*SICK*
