Copepods or something else?
We have a 75 gallon freshwater aquarium with 2 Green Severums, a Pleco, and some Silver Dollars. We have not lost any fish in over 2 months and do not see anything unusual on the fish. However, the glass and fake plants are covered with very small gobs of a stringy, gelatinous substance that waves in the water flow and tiny white pinhead “mites” that are crawling all over the place. The “mites” are very active regardless of whether the light is on and move around pretty fast. We’ve been looking through your site and think the “mites” could be copepods, but haven’t seen any references to the gelatinous substance. It has spread to the point now that the water looks cloudy due to the gunk on the glass and the fake plants look fuzzy. Even if this is harmless to the fish, it still seems to be out of control. What can we do? Thanks for you advice! Catherine and Matt
