Hi, we got 4 gourami a couple months ago, and they've gradually gotten less and less active, and now barely move. The fish store has said for 2 weeks in a row the water tests as perfect. At least one had gotten some black spots so I gave pimafix for a week but it didn't seem to affect anything. Any ideas? Or how do I know if it's ok to get new fish if these die? Thank you!
