What is this. Uronema or bacterial or just something random

4 green cromis 1 died but that’s nothing I’ve ever seen before. The other ones have weird markings on them that the first did not. The clowns goby’s and tangs are fine. Just These guys. I feel bad cause I can’t stop whatever it is from progressing if I can’t find out what it is. I’m feeding low dose food with metroplex and focus to hopefully stop it if it’s a bacterial or parasite. And I’m waiting on the dna test to come back. Any ideas?

Need pictures of your existing problem fish in white light and water parameters for medics. Were they quarantined? @Jay Hemdal
