Hi my red foot tortoise now believe to be a yearling has stop eating hibiscus flowers & other plant leaves all together, I have been feeding him/her more often with other alternatives since a few months ago with green peas, fruits, fish, chicken & Mazuri tortoise pellets. Certain types of tropical fruits are preferred & I am thinking of introducing it to cactus but fear he/she is too young to consume them, what's your suggestions?
