Is velvet a partasite also , like ICH ? I t only took 5 days to kill both my fish from the time I noticed anything wrong. B otyh continued eating well until the night before they died.
The people I bought the fish from are due back this week so Im gonna be interested to see how their tnak (the one these fish were in) aired.
Everything that has been put in my tank ( live rock, fish, 1 rock w/red mushroom) has all come from the same place so I am aussiming the isease , whatever it was, must have originated from them, I dont see how it could have been introduced any other way
Gonna do some seaches on velvet and do some reding, thanks fro the comments
Still appreciatte any comments as I have bene having a hard time deter4mining what desease it was for sure. I think if it was ich, it wouldnt have killed the fish so fast and the intial outbreak wouldnt have been so sever, but I could be mistaken
