What do I do with frozen food, i've looked at the packets in the store and there's no instructions. Do i leave it to defresot over night, or place it in a cup of hot water or? i want to buy some but i dont want to harm my betta.
then my hubby shouts "what the f.. is this in the kitchen"

I am amaized how complicated people make things when feeding frozen food.
I get a cube of bloodworm for example out of the freezer and literally "waft" it around in the fighters tank. As it defrosts, small amounts of bloodworm fall off the cube and the fighter eats it. You can feed small amounts or large...it's up to you and you just put the unused food back in the freezer.
I've heard people say various things in the past about this method....including "won't it chill the fish" and "what about all the juice that goes in the tank" ???
Been using this method for 25 years on ALL my reef aquariums and trops and it doesn't seem to bother my fighters either.
Try it....it's very easy, honest.
