I just got this cute lil fella couple days ago...he's still a baby around 2 1/2-3 inches..he is tanked with a baby tire track eel(which are like best friends..always sleep together, swim around together) and a baby silver arowana..around 3 1/2 inches..they all get along in a 55 gallon but the gold dat hasn't been eating..i tried feeding bloodworms and small cichlid pellets but no luck...any tips?
