Thanks for all that replied.I will try to find some type of garlic extract to soak my fish's food in.Can I use any from the grocery store? I have 2 cleaner gobies,and a cleaner shrimp but they don't seem to work.I do notice them cleaning but not enough.I don't think it is a space issue for those that asked .I have a 125 main tank and a 55 gallon sump.I have 2 tangs(orange shoulder,scopas), clownfish, lawnmower blenny,4 chromis,and inverts..I think a chromis that I got from petco( I know should have quarantined)may have introduced the parasites.
