ok, so Yesterday I went out of town for the day, came back that night to find one of my favorite angels dead. I dont see anything visable on the other fish, except 1 other angel has what looks like blood where his peck fins attach to his body. Anyone know what it is that causes that? Also the only thing new was about 5 days ago I feed them some black worms, I also rinsed them thourghly before feeding them to the fish.
