2 weeks ago I added the Lion Fish, and within 2 days he had ick spots. I treated the tank with reef-safe Ick cure, after 3-4 days the spots were gone. I put the carbon filters back in, and within 2 days the spots were back, and his eyes were now becoming cloudy.
Unfortunately, just because ich isn't visible any longer, doesn't mean it is gone. Ich has three primary stages in its lifecycle. We can only see one stage, the trophont stage. This is the stage that appears as white or salt spots on the body of the fish. This stage lasts only for a week and then it drops off the fish to continue its lifecycle. So, just because you cant see it doesn't really mean anything.
For the past few days I have been taking him out of the tank and dipping him in some Ick cure (blue stuff) for a few minutes each time. It seems to work a little, but the ick keeps coming back.
This is useless for curing ich. The problem is that ich is also alive and well in the tank, not just on the fish. Also, in the trophont stage (stage where white spot is present) ich is extremely durable. It burrows into the skin so that it simply can't be "washed away".
There are only two proven ways to treat ich: Hypo-salinity and copper. Neither of which can be performed in the presence of inverts. You will have to quarantine the fish and then treat the fish in the QT
tank for a minimum of 4 weeks.
We have two great articles on both ich and QT
. The ich article was written for FW
ich, but since FW
are so alike, a lot of good information for you is in there. These two articles are here:
Here is another good site on SW
This site will go into more depth on the little bugger and give instructions for carrying out hypo treatment.
I want to second scubasteve's response is telling you that QT
'ing a fish is the most important first step in bring livestock home. That way you can avoid all kinds of problems... Also, you need to keep an eye on the other fish in your system. If they come down with ich, they too will have to be treated.
