I got new fish 2 weeks ago,and one of my new wrasses just started to swim realy weird. I still have them in qt tank. None of them show any problems of ick, so that is good. I just want to know what it might have. If it is a blatter infection,what kind of antibiotics to treat with? Do I treat all of them since thay are in my qt tank? Will that harm my other fish by treating them with a antibiotic if nothing is wrong with them? He it eating good I feel. He is just swimming funny and getting blowen around. Please help. Dont know what it is.
