+ Be very very carefull with bought live foods, especially bloodworms, tubifex and even glass worms if they are stored uncooled and dry, in room temperatures they loose most of their nutritional value too. There are loads of bacteriae in them so you have to rinse them extremely well and remove all the dead ones. Especially bloodworms and tubifex are collected on highly poluted localities for commercial reasons and mostly contain high levels of cumulative poisons.
