Thanks for the advise. I have only had the black aro for 9 days now. I have checked my water parameters every day and I must say their right on. The ich seems to be just about gone after 4 days of treatment. I am really upset about his barbs shriveling up and everyone I talk to can't explain why. I just want to know if their going to grow back. Today I have noticed that my one peacock bass's eye color has changed. The outer ring has gone from a redish color to a bright orange. I hope that's not a problem. I must add that I have a teacup stingray in the tank and he is doing exellent, (knock on wood). Anyone ever have the barbs shrivel up on an arowana?
