Pics a little fuzzy but I have reason to believe this May be brooklynella and not ich. Ich doesn’t come back a day later and fall off to reproduce.Most similar symptomatically to Oodinum, this is also a parasite that primarily attacks the gills first. At the onset, fish may scrape up against objects, rapid respiration develops, and fish often gasp for air at the surface as the gills become clogged with mucus.1 Very quickly the fish will become lethargic, refuse to eat, and its colors will fade. The most noticeable difference that sets Brooklynella apart from Oodinium is the heavy amount of slime that is produced by a fish that has contracted this parasite. As the disease progresses, a thick whitish mucus covers the body. This will usually start at the head and spread outward across the entire body. Skin lesions appear and it is not uncommon for signs of secondary bacterial infections .measures. Quick cure in the form of formaldehyde is the treatment of choice.
Typically a standard formalin solution is mixed with either fresh or saltwater in a separate treatment container. Initially, all fish are given a quick dip in the formalin at a higher concentration, followed by continued treatment in a prolonged bath of formalin at a lower concentration in a quarantine tank (QT). Of course, the longer the fish are exposed to the formalin treatment, the more effective it will be at eliminating this disease.If a formalin solution is not available for immediate use, temporary relief may be provided by giving fish a freshwater dip or bath. Even though this treatment will not cure the disease, it can help to remove some of the parasites, as well as reduce the amount of mucus in the gills to assist with respiration problems. Once the initial dip or bath is done, place the fish into a QT under hyposalinity to help keep any possible new free-swimming protists from infecting the fish again, and then obtain a formalin medication as soon as possible to begin treatment.
