I've had 2 clownfish in qt for the last month, one has never shown an kind of blemish the other had 2 spots show up on either side about the same pattern to each side. I had added a hermit the day before looked an awful lot like the claws of that crab. That was 3 weeks ago, looked fine ever since. I moved the fish to the my dt yesterday that has never had a fish in it. This morning one still looks perfect as always the other has spots in several locations. Is it ich just now showing up. I mean could it by that prolific in a new tank without a host or maybe I happened to move the fish the day it shows up really bad? Also how long do the spots show up after the parasite attaches?
