Red Zebra Cichlid Sick?

Ebonynivory06

I have a Red Zebra cichlid that appears sick. Hanging out on top of water. This one gets chased a lot by the other Red Zebra. There are also two guaramis in the tank. Amm was at about .25, nitrites were kind of high, as were nitrates. Just did water change on tuesday. Seems very lethargic except for when being chased. Established tank of 6+ years, bought from someone recently. Should I put it in an isolation tank so it can rest?

You tank is tank is not established. There should be no ammonia in the tank at all. That i your first problem. What is your stock and what size tank and what filters are you running?
