I introducted a new Clown loach last week he was about 2 1/2inch and he must of had ich/white spot as my whole tank then came down with it

. I could cope with the diease with fish medicine, But the worst thing was that a few days later(2) all five of my Clown Loach were no longer with us

1 was 5", 3 were 4 1/2" and the other 1 was 2 1/2". some other fish (Tiger Barbs, Yo-Yo loach) died too, but my catfish are still alive and still looking healthly.
It was a really sad day no i've got to try and get the tank back to normal again before i put any more fish back in.
