I want to start making my own food for my fish. Heres what im doing. I just bought HBH Super Soft Spirulina and Hikari Micro wafers, im going to grind those two in a pepper grinder and cut up some shrimp, then im gonna throw all that in some ice cube trays w/bottled water and freeze it. I was wondering if i should add any other foods to the mix such as romaine lettuce, cucumber ect.
