Calico Fantail and black moore problems

Question
I  have recently set up my tank again to house one calico fantail and one black moore.  I've had them around a week and a half and a few days ago i noticed white spots on the black moore, I went to the store and noticed the fish in the same tank had this problem and they told me to treat with white spot.  I've seen no improvement in the black moore, infact he has started to get tail rot and is now pretty much covered in spots, not swimming very much.  I've treated him with the white spot and added some salt as i've seen this suggested else where.  I'm starting to lose hope now.  Any suggestions? at the minute the fantail is starting to show somes signs of white spot on its tail, plus it is spending alot of its time on the bottom hiding in the plants

Thanks and i look forward to hearing from you

Answer
With White spot... or ICH ... you have to raise the water temperer.  It has a nine day life cycle of which 8 days it is immune to medication.  The raised temperature will decrease the life cycle to about 3-4 days and you should be able to kill it off.  Keep me posted... dave
