i was scared sombody was going to say that,if i take the fish out will it keep it from spreading throughout my tank?
more than likely not, if your fish has it, it is almost certain it's already in your tank... but a single white spot does not necessarily mean Ich
Answer:
1.) how long have you noticed the spot?
2.)is the fish doing/displaying anything else out of the norm?
3.)breathing fast or heavy, itching on something?
4.)swimming in a stressed pattern?
5.) Have you recently done/changed/added anything to the tank?
6.) What are your water perimeters? (Ammonia,trites,trates,phos,ph,temp,salinty)
7.) Any other fish in the tank? What kind?
8.) Any other fish in the tank have white spots or that you could answer yes about to Questions 2-4?
9.) What are you feeding the Mandarin?
