I just received a shipment of 30 cichlids for my new 120 gl. tank. I hooked up a drip line for an hour then put them in the tank. with in 5 minutes i noticed two of my yellow tails have little white spots on there lips. No other fish have them. It looks soft like a small piece of cotton. My guess is Columnaris??? Should I wait to see if it clears up, I'm a little nervous about doing a salt dip this soon after transport, plus I'm a little new to this. My tanks chemistry is good, I did a fishless cycle. I would include a picture if they would sit still for 2 seconds.
