Oh - Jim - I wish I could help you. I have been posting for about 3 weeks regarding my Ich problem. Here is what I have learned so far.......
Options
1. Remove all fish - treat in separate hospital tank with a quick freshwater dip and some antibiotics
2. Try feeding with garlic soaked food - theory is that the parasite supposedly doesn't like the garlic taste the fish emits so they don't stay on the fisha and eventually die off.
So far I haven't been able to remove my fish because of the rockwork etc. I lost my Hippo Tang and a Spotted Hawk. My
Royal Gramma looks like it is going to go today and the
Flame angel will probably soon follow.
I have learned that Ich is caused by stress - Since my system is relatively new I must have had some type of chemi bloom that freaked all the fish out....then if one comes in with a 'cold' the rest have their resistance down and bingo.
I also heard that warm water doesn't help - so look at your temperature. This is another thing I can't control without a chiller because my tank is in a closed system and I live in South Florida - my water stays at 82. ( I was getting a 3 degree daily shift which could have been the cause of the stress as well - but now that is stabilized).
I wish I could be more helpful to you. But without removing the fish from the inverts there isn't really a medication that will work on one without killing the other.
I will watch this thread in hopes that someone can be more helpful to both of us!
GOOD LUCK!
