Ok, need some help here on fish health. What does clamped fins, stringly excrement, slightly paler than normal colouration and decreased activity gennerally indicate? No new introductions of any kind have been made within the last few months, no major changes lately, all other inhabitants are acting normal (soft corals,snails, hermits, cleaner shrimp, yellow tang, perc. clown) and haven't thoght to test water prams yet (will do that as soon as I finish posting). The fish showing the symptoms is a "polka dot cardinal". Couldn't find anything in my books other than the clamped fins indicate disease or illness, however I knew that already. More details can be provided if needed. Fish health is something I know relitively little about, so any and all help is highly apprecieated.
