Hey guys, this morning i found my smaller angel dead in the hiding spot and the other fish were picking him apart. I dont know what happened i just thought it was an aggression problem and others killed him. But now i see that my 2 other (white) Angelfish have red stripes all over their body and on their face. I dont know whats happening,this is new they were white with black stripes and they're getting red color. Is it a disease or nothing to worry about??
