Ich?

[Bullieshockey]

I have a tank with aggressive fish only. I have had it up and running for about a year. In the last week all my fish look like they got ich. But now they literally look like something is eating their fins. My lion fish is rotting away. My clown trigger has white spots every where. I have done 4 water changes and now treating. Can anyone help?

Sounds more like velvet to me: https://www.reef2reef.com/threads/velvet-amyloodinium-ocellatum.217570/

The fin rot could be a secondary bacterial infection: https://www.reef2reef.com/threads/bacterial-infections.191511/

This is exactly my thought. Get a 55 gal quarantine (assuming you have several dirty, large fish) ASAP!

Added any livestock recently? When was the last fish added. Some pics would help to diagnose over the internet.

After reading the article I am pretty sure it is velvet. This sucks. I have had fish for a long time and never had this happen. Right now the trigger is still eating.
