Milk causes a reaction that deoxegenates water which causes fish to die so a milk spill into a watercourse is pretty devastating to fish, weather they can survive in milk alone or not I couldn't tell you
alavahalf, that is an amazing idea, why has nobody ever thought of that, I might try that with my next fish, they keep dying when i put the in my cereal, nt sure why.
Full fat is more like bl00dy cream than milk, horrible, skimmed is like watered down milk and semi skimmed is just right, as for humans milk, well its been a few years since i tried that so i forgot, i'd say we're talkin about semi skimmed, its most popular. Isn't it?
