Anyone ever have problems with a fish stop eating any particular food? The past few days my chocolate cichlid won't eat either of the pellets that I feed my tank in rotation. It shows interest and pulls the food in its mouth but spits it back out. It then proceeds to go around the tank and goes up to the pellets in other places and either does the same thing or get close to the pellets then backs off. I feed Hikari Bio-gold and Excel. Fed the tank the same rotation of food for the past 5 years. Haven't noticed any other behavior changes other than this. Full grown Chocolate, had it around 3 years I think. Nitrates were a little higher than I would have liked them before I started a water change. Was around 40 ppm, Pushed the water change a few days longer than normal. Any ideas? Should I be worried about the possibility of a developing sickness?
Any help would be great!
