I have two oysters, three fish, and two snails that I love very much. In this post today, I’m going to share what I feed them all.

Many people often ask me what I feed my oysters, mostly because they’re such an uncommon pet. However, the oysters are far easier to feed than the fish. Oysters are filter feeders, and live off of phytoplankton. I buy mine off of Amazon, and keep it in the fridge. I’ve been buying this particular one since I first got oysters, back in the spring of 2016. Once one of my friends almost convinced our other roommate it was a green juice, but luckily she knew better than to try drinking it.
I shake it regularly, to prevent the plankton from accumulating too much on the bottom and dying, and pour in a tiny amount every day or every other day. I make sure my air pump is on, to make sure the plankton will float around the tank and make its way past my oysters’ shells. I can tell they can tell when I put the plankton in—they open up and start feeding almost immediately.
My two picky eaters are Nemo and Kai, a clownfish and royal gramma, respectively. Though occasionally both will respond to NutriDiet Marine flakes, usually they both just stay in the spot where I feed them from, hoping I’ll give in and feed them something better.
Nemo is a huge fan of Hikari Marine S pellets. She will speed across the top of the tank, chasing after every pellet. Though the pellets say they will sink, they take a long time to do so and my clownfish usually eats them from the surface, ignoring them if they do happen to sink before she gets to them. Kai, being very shy, refuses to venture to the surface. He used to occasionally gobble the pellets that sink. However, since I’ve introduced frozen brine shrimp as an option, he now completely ignores even those pellets that sink.
I’ve been using Fish Gumdrops, of frozen brine shrimp. I buy them at my local Petco, since shipping frozen food is extremely expensive. Though the package encourages dropping the gumdrop in straight, since Kai is the only one that eats them I usually defrost it in a small cup of tank water. I add a clove of garlic, to make it more appetizing, since I was worried Kai wasn’t eating much due to his shyness. The defrosted shrimp also float for a bit in the middle of the tank, rather than sinking immediately or resting on the surface, so they’re ideal for a shy feeder like my royal gramma. Nemo chases but ultimately never eats the shrimp, while Kai will actually pop to the front of the tank to snag a larger morsel (the only time I can see him so clearly).
I even tried making my own fish food, based on a YouTube video, but the food was completely ignored. So for now I’ve settled on these, though I would like to find more types of food they like in order to diversify their diets.
As for Kona, my lawnmower blenny, and the snails (who have not yet been named), the algae in the tank is plentiful, enough so that they do not require any supplemental feeding. If one day my algae actually subsides, I’ll be looking into how to make sure they’re still well-taken care of.
