Hello everyone! It has been awhile since i’ve had a problem with my tank. My tank has had marine ich for awhile, i am 100% certain it is ich. It initially appeared on my clownfish and i had treated only the clownfish for 3 weeks with Ich-X which literally does nothing. Both the method i used and the treatment did nothing but since then I’ve not really had any issues, I haven’t had the time to let the tank fallow so i haven’t eradicated it. I use a UV sterilizer submersible in my tank it helps keep the parasites down. I left for a week and came back. My tank was very low on water since i haven’t set up my ATO. I think the sudden drop in salinity causes a stressful event in my tank and they also haven’t been getting fed as often. My Yellow Coris wrasse has a huge dot on his fin and it doesn’t look like ich. I remember reading about another external parasite that attaches to the fins but i don’t remember what it’s called. Can anyone help me identify? I’m planning to treat them all with copper before i move to college but I only have 3 weeks and Ionic copper. Please help!
