Appears to be my friend, Keep a real close eye if more develop.. Also look for signs of scratching on the rocks. Invest in a cleaner shrimp, Garlic Extreme, Cleaner Wrasse, raise the temp or you may want to QT, or try a FW dip. Which is 1.10 Specific Gravity for 15 minutes and have the temp the same as the DT.
$HIT! How did this happen??? Can Ick hitchhike into you tank on a coral? Anyway, will it infect the others?
Best to get a cleaner shrimp (hope it help cleans it)
Also keep that tang nice and feed with garlic.
It should past - if he is nice and strong. :fish:
The PH MUST match to do a dip.
A FW dip will not get rid of encapsulated cysts.
I also would not raise the temp in the tank as in Marine Ich it does little to shorten the life cycle of Ich (like it would do in FW Ich). More heat in the water lessens the amount of available oxygen, which in this case is a truly bad idea.
How many fish are in the tank, do you see these on any of the others?
