I have not seen him poo so im not sure about the color. I just tried digging out a earthworm from the garden and gave it to him. He looked at it and then ignored it. Im hoping RedRaven is correct. Maybee he just needs a little more time to settle in. I dont want to foul the water by adding to much food. Ill try a few nls pellets again later tonight. Ill add a little garlic like suggested.
