Hi Barbie,
Sorry, I was in a hurry to post, as the fish were dying fast. I live in Canada. The 30 gal. tank has been up and running over 5 years, no problems. Water tested perfect. I only have 3 fish that haven't died. A platy, catfish and neon. My plecko died this morning. He was over 5 years old ...

Hi,
I'm new here and really could use some help with my fish. I have a sick plecko, (and other fish.......platy, catfish). I added 2 platys a week ago and now my fish are dying off.
They have ich, peeling skin, not eating, fin rot slightly.
I have removed them all from the tank.
What meds should I ...
