i got him about a week ago. he hasn't eaten since. i've been trying to feed him nature zone probiotics, crickets and romaine lettuce. nothing seems to work :/ he has adapted to his enviorment however i noticed he rubs his eyes and one of them is swollen. i'm assuming its an eye infection so i bought drops and now they're opened. water temps are 75ish nothing less. he has a filter, basking spot, plants to hide. heat and uvb lamps. whats wrong with my little guy? how can i get him to eat? and he's sleeping a lot what's wrong with him?
