OK.. so i guess then i'll try the tropical mix, and the bloodworm, and anything else I can pick up, and will rotate the food, and feed little amounts twice a day (will cut each blister into quarters, feed 2 quarters a day unless there seems to be a need for more food.
it's generally recommended that food should be eaten within 2-3mins of adding to the tank, otheriwse you could be over-feeding. This doesn't relate to things like algae wafers or cucumber slices though, as these will be eaten over a longer period of time.
just a heads-up on the frozen food, you should thaw it before adding to the tank. You probably know that but just in case. I use the same plate for thawing and never wash it with cleaning products, just rinse with boiling water. You dont want household chemicals ending up in the food/tank.
