My juvy Yellow Rat is refusing to eat. I believe the last time he ate was 2 1/2 weeks ago and he only ate ONE pinkie when he usually will eat 2-3 a sitting every 7-10 days. I have left the pinkies/fuzzies in the tank with him for several days and he doesn't touch them. The temp.has NOT changed and has been around 80-84 degrees on the warm side and a few degrees lower on the cool side. Any ideas or suggestions? Thanks for the help in advance!!
