I have 3 irredesent sharks with my new 8in arowana. It appears as though the sharks had ich (which I didn't see at first) and now my new arow has it. I have spiked the temp to 84,added salt and ich medicine, and I am now doing a 50% water change every other day. It has been almost a week and the ich is still not gone! The arow looks kinda pale, and I noticed that all of her back fins are falling off. SOMEONE HELP PLEASE!!! The white spots are everywhere and I don't want her to die. Any advise?
