As you all know who have read my last posts, my main display tank has Ich.. I am treating with a combo of Kick-Ich, Garlic, lowered salinity (1.019) and raised temp (81). It's working.. SLOWLY. The grouper appears to have kicked it's ailments.. no more scratching.. doesn't hang out as much in the jet stream from the pump. The lion still has some cloudiness on the eyes (appears to be ich cysts on the eye) as well as white spots on it's fins and body.. last night.. tried to eat a small scallop, but spit it out (immediately gobbled by the grouper).. also has taken to hanging out in the inflow from the wet dry. I'm afraid he's heading downhill.. what a loss that would be.. he's such beauty!
...one of my feather dusters lost it's crown, but I understand this is normal with changes in water chemistry.
I guess my big question is.. once a tank has Ich.. how to reduce a possibility of a relapse once it is cured? My original plan was to add a tang (probably a Regal).. but now that the tank has had Ich.. am I limited to tough fish like the grouper and Lion I have now? I can't treat with copper as I plan on keeping my live rock, hermit crabs, feather dusters.. and later.. some starfish. Please tell me I haven't made a mistake getting into the saltwater hobby again!
