Where did they first contack the ICH at?? wasn't it the 55 gal? YOU treat the tank that they had it in,, placing them in another tank is infecting that tank.. IF you have too, place the guppys in the smaller tank away from the meds.. ICH can only be treated once they FALL OFF THE FISH.. NOT while they are on them.. Their heads are buried into the fish, so the meds dont' affect them..
YOU also need to leave them in the meds for a few days to work, that is usually the last treatment to kill out the ICH..
BUT follow your directions.... ICH does not like salt.. So if you added in some salt, that will take care of them too.. BUT the ones on the fish is the problem.. IF you feel that you have to much salt in the tank, on the next two water changes, DON'T add any SALT, That should be enough to delute it down.. Do what the directions say on your ICH meds.. IF you see more, then turn the temp to 82F and wait for them to fall off, THEN treat the tank.. In two days, turn the temp down to the normal temp and it wil come down on its own.. Sound good??
IF you ever dought what someone tells you, always ask SEVERAL ppl.. YOU did great on not adding in to much at one time.. Your fish are to small to go through to much, but you would be surprised at what they can and cannot handle.. Keep the temp in both tanks at the same.. 76F OR 78F to keep aggression down..
