2 days ago i added a vine in his cage to help him get to the feeder bowl i put in. Ever since i did this he has been climbing and staying on the top screen just doing circles on it. yesterday his color was normal now its more black. The temps are normal as they have been. cage is 18x36x48 lights are rasied about a inch of the top screen to keep him from burns. basking area is 85-90 with the middle around 70. I have a 18 week old nosy be. any advice would be great. also he normally eats about 5 or so medium size crickets a day lately its been about half that. im trying to get him to use the feeder bowl.
