Just a few more ideas;
1. Mollies and many of the live beares get ick (white spot) easier than many of the egg layers. Years ago if you kept mollies you added a little salt to the water and kept the temperature higher. ( 78 to 80)
2. Overcrowding will make ick spread quicker
3. Older fish ( because they are weaker) get ick easier
4. If you see ick on 1 fish isolate it ASAP. If you see it on many fish you might as well treat the whole tank.
5. as mentioned; If you have shrimp you can not use any treatments that cotain copper. Malachite green is a good tratment for ick but it is messy and will stain the silicone and other things in the tank.
6. Also as mentioned; You have to continue to treat after the ick apears to be gone. ( not sure how long but probably 5 to 10 days) Good Luck; This is a great hobby , Don T.
Thanks Don. I did read about the whole salt thing somewhere.. the tank temp is currently 26 is that equivalent to 78-80? Ive looked at all the ingredients on the treatments and what it contains... theres not alot! how can i tell if treatments contain copper.
I know!! I feel totally addicted! I didnt realise fish could be hobby! Its a shame uni starts soon... feels like itl be cutting into my time!!
