Hello, I have a 12 inch male red dovii in a 5ft 120 gallon tank (eventually I wanna upgrade to at least a 180 for him) I got him about 2 months ago from a bad situation in a small tank, since he’s been with me hes been eating pretty well but I still find him quite skittish and not fully comfortable in the tank, any suggestions how to make him feel more at home?
