I am a new RES owner ( got him from a friend that couldn't take care of him anymore) his name is Angus and is approx 4 yrs old.....i was told he eats cooked chicken ..and cooked roast beef...i also bought him some Turtle bites pellats but i cant get him to eat them... do i put them in the water? or will he take them in on his own? was also told to get him some plants to chew on...which ones are better? he wont take any romaine lettuce or any other veggie i offer... another question...how often do these guys eat?? thanks in advance i appreciate the help :)
