1: The color of the fish, they seem to be changing to a tan and blck instead of staying their normal black color.
2: I dont know the ph level.
3: They dont get a variety of food, because they are my friends fish.
4: We have just raised the water level a little to make it warmer.
5: The water is changed at least every two weeks.
6: They are breathing kind of slower. They havent eaten in about two weeks. I dont know what else to tell you but hopefully this will help a little.
Hmm no food in 2 weeks, thats not a good sign.
Is there a heater in the tank? Do you age the water before changing it or use a good quality conditioner?
Maybe if you put them in a hospital tank and treat them and do a 100% water change along with disinfecting the tank. Then once the main tank is ready do small water changes every day or 2 to keep the water quality high and keep the carbon out for a while. Also dont put in any gravel so its easier to do the above.(oscars are realy messy)
If you do this there will be no need to keep an eye on the ph just the temp, maybe keep that at about 29 deg celsius (you will have to convert this to farenheight, we only use metric in australia)
Anyway sounds like they are in bad shape maybe one of the over members who have more experience than me can make some suggestions.
Hope I have helped
