it's definitely a disease then. I used "Garlic X-treme" before to make picky eaters eat. Garlic is a smelly irresistible treat, so you can soak the seaweed or rinsed mysis in a little cup with a few drops of garlic x-treme or other garlic additive. Some of these additives also have different vitamins so you may as well get that one. Extra vitamins = extra strength, which is what your tang needs at this moment. I really hope it gets better, bud. Keep us updated.
