How much should I be feeding guppies and tetras?

It depends how many fish you have, start with a small amount a few times a day. Only give as much as they can eat in a few minutes or your tank will get polluted with uneaten food. Hope this helps

1.5kg is a big tub,but works out so much cheaper,but.....any idea what (if any) the sell by date would be?

I bought the 120g tub and I have 2 tanks a 1000litre and a 57 litre, I feed once a day, this lasted me at 5 months granted it was mixed with other foods as I have an assortment of fish. I would say unless you have a lot of tanks 1.5kg tub will probably go off by the time you get to the end of it. There is a best before date on the tub on mine it was just over 2 years from date of purchase

Can I feed my goldfish this too as I have some temperate fish in with them in another tank?

I have no idea but it does say for tropical fish. Fish eat pretty much anything so they'll most likely gobble it up still!!

Is this a medicated fish food ? I need an medicated antibiotic fish food

No it's not medicated, but I understand the confusion with the name of this product. This food contains probiotic bacteria ensuring your fish digest and absorb more of the nutrients, resulting in less waste and improved water quality. Stimune supports a fish’s immune system keeping them healthy and primed to fight off disease.
