I have 4 clown loaches they are approx 5-6 years old and are in a 120 gal tank. The tank is well established as is the filter. I have live plants, no c02 and do water changes weekly and sometimes be weekly. The only thing i test is nitrates which is about 4. One of my loaches who is the shyest of the 4 can only swim upside down and seems to lay on ground on it's side with heavy breathing. I know how loaches behave and this is not the normal behavior of a clown loach. I do not have a quarentine tank as I haven't had a sick fish in long time. I just cleaned the filter a couple days ago. I recently added some new plants. I did notice that for temp on the aquarium had dropped to 73 degrees which is lower than I usually have it. I have turned it up and I did another water change this morning. Is there anything else I can do?

Keep water temps stable. I had aquarium in garage, fish would act really weird at low temps. For tank that old, nitrites should always be zero. Do you keep any media away from tap water while doing cleanings? And is tap water treated before doing water changes?
