so today's ago i noticed white spots on my smallest clown loach. i hve a 120g comm tank with a diy sump. so far i have only noticed him with spots but my betta has been hiding alot i guess trying to to get sick. my larger loaches about 3.5 inches i have noticed rubbing on the rocks. no signs of white spots yet but im guessing they are infected also. so i started dosing salt and raised my temp to 80. afraid to go higher since i house so many diff fish in the same tank. afraid also that to much salt is going to kill all my plants. anyway my question is anything else i can do? and how long does it take to see the spots go away from the fish . i guess so i can know that the ich has been killed or suppressed. thanks for any info
