Just a little PSA about Lymphocystis vs Crypt (saltwater ich). Lympho show up as CLUSTERS of cysts, often on the edges of find. Ich will show up as a more evenly spread disease, on the fins and body alike, with no real preference for location.
Lympho is viral, and crypt (ich) is parasitic. There is no treatment or cure for lympho, it is not typically deadly or particularly contagious. Ich can be treated and cured easily.
Based on that, which disease do you think this butterfly has?
