Reviving this old thread as I found it while searching for similar issues.
I just received my clown from a known Quarantined facility laat friday and noticed this bruising behind his fin today. He just finished a week long hunger strike while settling into my tank. Hoping it's not a uronema or similar parasite. The vendor and I are just keeping a close eye on it to see if it's just a bruising or injury or whether it progresses. I'll keep the thread updated.
