I got a royal pleco yesterday from my lfs and i put it in my quarantine tank and ive had the lights off in there to reduce the stress, but when i went to turn the light on this morning i noticed little white spots on him that i think is ich. I have raised the temp to 81 so far but i have it set for 84. I added salt and stress coat. I was going to ask if there is anything else you guys recommend me doing? I have copper but i don't really like to use it. Is copper even alright to use with plecos? Any help is appreciated because i don't know much about these fish. Thanks for your time
