LOL, wise response, as I save my roaches for later also.
Seeing as how i got 3 fish in my tank, all cats, my shopping list is relatively small. Hikari sinking carnivore pellets, hikari algae wafers, tetra river shrimp(for handfeeding) frozen beefheart, frozen brine...
for smaller fish, get a glass of warm water, throw in a frozen block of brine, along with some tubifex and bloodworms... stir it around and pour it into the tank, fish go crazy
