I am new here so forgive me for any ignorance. I need help! I have a new black arowana that I just put in my tank a few days ago. I have 2 peacock bass and 1 teacup stingray with it in the tank. I think the arowana might have some type of skin parisite, ICH. It looks like tiny pieces of sand on the sides, top and eyes of the fish. I started using Rid-Ich that was recommended by the place I got him from. I also have slowly raised the temp to 86deg. This is the third day/treatment and I think it has helped. But I have noticed a few changes and wanted to know if this is normal. The two wisker type entenas on the top of his mouth have shriveled up and I have noticed he is breathing a bit more rapid. Is this something I should be concerned with? Any advise would be greatly appreciated. Thanks in advance.
