yesterday i noticed my regal tang was swimming in circles scratching him self on a rock.

isnt this a sign of parasights?

he did it for maby 40 seconds thren stoped, he hast done it yet that ive seen. so i am hoping he just has maby something on him or bothering him on his side. he has done this once before when i had my red slime out break, each morning he would have alot on him

if i continue to see this behavior, whta should i do?

i dont have a hospital tank

maby a freshwater dip, isnt that what they are used for?

i have never done one before though

thanks
