My new little clown(2 weeks) is looking really thin. He is more interested in the anemone than the food. The food goes by and he swims after it for a second and goes back. Should I move him to the seahorse tank, and how long can I keep it by itself before it turns female? I don't want to move th female too but I guess I might have to. Please Help Me! I don't wan to lose my Black Clown!
