While pinkie mice are relatively high in protein (approx 64%) and relatively high in fat (approx 17%) warm blooded animals contain the wrong type of fat, which harden within a cold blooded fish, and over time can eventually lead to blockages & fatty deposits around the liver. Over time this can have a cumulative effect, even when fed on a non regular basis.
Also, the relative proportions of amino acids within mammalian proteins are different than those required by fish, so much of that 64% protein will be excreted as nitrogenous waste placing an extra burden on your bio filtration, and your overall water quality.
