I need help to determine wether this is a set of injurys to my oscar or is he comming down with some kind of illness. I have a 1 2.5 in RES with 5 in oscar and 1 3.5 in oscar a 20 gallon long. (I know this is to small my LFS has my 75 gallon on back order, and this is to grow them out and will be my turtles home) My water parameters are within range and only affected by green algie blooms (tank is near a window) so its expected. It started yesterday with teh white what looks like 3-4 white dots,I have researched ICH and viewed pics of it and this looks to be localized to just this one oscar and looks to big to be a parisite. Then, today I wake up to find that he has what looks like a fat lip, looks a little red. I thought ICH at first then movede to teritorrial aggresoin but the other fish looks healthy and happy and is a good 1.5 in smaller. I never see any fighting even during feeding all fish are happy. I bought them 5 months ago when they where about an inch.
