I currently have 12 blue danios and 1 panda cory. (I know that the cory can’t be there on his own. I’m rehoming him on Sunday.) They eat flake food, sinking pellets (although the danios always seem to get to those before the cory) and occasional peas or cucumbers. Are there any glaring gaps in the nutritional content of their diet? How should I supplement their diet/add variety to it? Is there any homemade food I can make that doesn’t require cooking invertebrates?
