Where do my fish eat?
Surface feeders will tend to have “superior” mouths. These are up-turned and looks a bit like a frown. Examples of these include the danios, white clouds, butterfly fish and hatchet fish. Those with down-turned mouths are termed “inferior”. Not surprisingly, these fish feed off the bottom. Some examples include various catfishes and loaches. Fishes with “terminal” mouths tend to be more versatile and can accept feed throughout the water column.
