two of my fish died today one this morning and one tonight (5 minutes ago)
i'm thinking it was ebcause of velvet disease but not really sure...
-when they died they both sunk
-the both had a very thin layer of gold dust
-they didn't move much..
-mostly stayed either at the bottom or top
-didn't swim very well
-ate but not alot...
had no redness, no fin tears or anything...
also i have a catfish and a fry in the tank and it's to late to go to the store now...
what shouold i do to try to make sure they don't die...?

PLEASE HELP ME!!!
i'm really sad..
