Not Eating

[golfin0304]

I have a 55 gallon tank and 6 large silver dollars that I have had for 7 years. On occasion I notice that some of the fish don't eat and the food just floats by their faces. The last couple of days I have one large silver dollar that hasn't eaten in a few days and all the others are eating normal. Any ideas?

First off, fish can survive for weeks without food so until it has been a LONG time, thats when you should be worried. Does your fish look bloated at all? Also, Welcome to MFT!
