White spot on Tailspot Blenny

Pudgeshambley · Sep 1, 2023

Can someone tell me what this white spot is? I just noticed it when I got home. I have had the fish for two weeks. I have 2 clownfish and a yellow watchman goby but they seem to get along great. Barely pay attention to each other. Behavior seems normal and he has been eating. He has had brown stringy poop a few times but I read that was probably from constipation. I also assumed stress probably. Purchased the fish as quarantined from Dr. Reefs so has previously been treated for parasites. This is my first tank so any help would be appreciated. Tank is a year and half old.

Looks to be a minor scrape. Just watch to see if it gets larger or starts to go deeper into the skin….that can be a sign of a secondary bacterial infection.

Thank you so much. I guess fish get scrapes from the rocks? Do you know how long scrapes normally take to heal?

I've seen scrapes take a month or so to heal fully. Like I said though, if it grows or gets deeper, you'll need to treat quickly - gram negative, broad spectrum antibiotics in a treatment tank.
