Feeding a tang

[tebstan]

So it seems I should be worried more about the goby not eating enough than the tang eating too much. He's looking emaciated and sad. Its only been recent, since the tang was added. I've had the goby for 8 months. Everyone else is fine, and the parameters are good. He just doesn't go after the food like he used to, so I'm adding more to give him a chance around the piggy tang.
