I currently have a 20 gallon tank with 4 male guppies, 4 sunburst wag platies, an algae eater, and one surviving black molly. I have the marineland penguin 150 filter, a heater, air pump, gravel, and decorations.
I recently purchased and planted live plants on Saturday of last week and my excitement took over so I did not quarantine the plants. On Sunday afternoon, I realized that my black mollies were acting a little unusual. The black mollies were not swimming around the tank but instead were laying on the gravel. Upon further inspection, I realized that there was white specs on the side of two of the black mollies. I looked this side effect up and diagnosed the problem as Ich. I drove immediately to the store and purchased Ich treatment. I followed the recommended directions; took out the filter cartridge, vacuumed 25% of the water, and gave the appropriate dosage. I have been giving the recommended dosage once a day since Sunday.
Two days after the treatment began I came home from work and saw that one of the black mollies was stuck in the filter. Depressed, I removed 25% of the water again and continued with the treatment. Three days after the treatment I came home from work and saw another black molly dead in my tank.
The third black molly seems to be getting the white specs and I am fearful. The other fish do not seem to be affected by the Ich which is confusing to me.
Please help me!
