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!
There are a some things you could try for a few days:
1. Make sure the nitrite levels are zero.
2. I'm not familiar with your filter, but if it uses carbon, then remove the carbon.
3. Increase the water temperature to around 28 degrees Celsius (82 F).
4. Add aquarium salt at the rate of one teaspoon per gallon of tank water.
Are you sure it's Ich? A sure sign of Ich is that the fish "flash", that is, try to rub themselves on the gravel. It could have been something on the plants, I guess you'll never know for sure.
If it's possible, put the infected fish in a quarantine tank.
