I try and feed a varied diet. The puffers get frozen shrimp, clams, or mussels most days, frozen bloodworms some days, and live snails once a week with two fasting days each week. They get freeze dried shrimp as "treats" on occasion. My marbled crayfish gets hikari crab cuisine as a staple with occasional frozen bloodworms as a treat. Sometimes to switch things up I'll give her a shrimp pellet instead of the crab cuisine, and I drop in a little zucchini or cucumber or a small chunk of the seafood I'm feeding the puffers that night at least once a week. The freshwater fish get a staple of shrimp pellets, omega one flakes, and omega one pellets, with frozen bloodworms and fresh zucchini or cucumber about twice a week. I buy most of the seafood I feed at the grocery store instead of the LFS
to save some money, and I slice and freeze zucchini and cucumber to keep it around and easy to feed. I also drop in algae wafers for my bottom feeders from time to time. Every once in a whiles hatch baby brine shrimp as an extra treat. And if it seems like I spoil my fish, before I had to rehome my cat I was weaning her onto a raw diet, and when I had rabbits they ate mostly fresh veggies. My pets eat just as well as I do.
