I spend about $30 a month on random foods i find at every new fish store that i visit.
Ocean nutrition 's frozen foods are my least favorite, with exception to their invertibrate food in the purple carton. It is the only one you can thaw and disperse in water.
Hikari frozen are not my favorite either, but they are inexpensive and make a good delivery system for aminos and garlic.
Rod's and PE mysis are the most expensive for a reason, however, v2o foods are the inexpensive amazing frozen food product that is worth purchasing if ever you see it.
