Well I got up this morning and was sitting in front of my aquarium eating breakfast, and I noticed that my 3'' Oscar has a big white spot on his uupper fin.. Thanks to the research ive done on this site, im pretty sure that its ICH. Hes in a 55gallon along with a 3''Jack Dempsey, and a 3'' Green Terror, and 2 4'' common pleco,none of the other fish are showing any signs of the disease.. Ive read on some other post that I need to raise the temp,and and add some aquarium salt. Im gonna wait until next week to do this because I just changed my water yesterday. My question is, will my fish be alright unitll next wendsday,or do I need to act immedietly? And what temp and how much salt per gallon should I use for these specific fish? Thank you..
