    Buyers Guide – Choosing the Best Foods for Silver Dollar Fish

    Silver Dollar Fish Diet Basics

    Silver Dollar fish are not overly picky eaters, but you do have to feed them the correct foods. What is really funny to note is that Silver Dollar fish are in the same family of fish as piranhas. However, unlike piranhas which are exclusively carnivores, silver dollar fish are virtually 100% vegetarian.

    Although they are mostly vegetarian, they do enjoy the occasional meaty treat. Things like mosquito larvae, brine shrimp, and blood worms make for good meaty treats.

    When it comes to vegetable and plant-based foods, things like algae and algae flakes, vegetable flakes, spirulina flakes, as well as lettuce, watercress, and cooked romaine or spinach are all go-to options as well.

    What Do Silver Dollar Fish Eat in the Wild?

    In the wild Silver Dollar fish eat mostly all plant matter, and they do enjoy algae, various water plants, and veggies too.

    Do Silver Dollars Have Teeth?

    Yes, Silver Dollar fish do have teeth. They actually have fairly large and sharp teeth for their size. They may not look like a whole lot, but they can definitely do some damage.

    These fish are actually known for being quite aggressive and will destroy all sorts of aquarium plants (here are some safe plant options). If they feel threatened, if they feel as though their territory is being invaded, or they just have a temperamental tankmate, these guys can be very aggressive. They do often attack other smaller fish, often injuring them with those sharp teeth.

    How Often Do You Feed Silver Dollar Fish?

    Silver Dollar fish are very voracious eaters in the wild and will eat constantly. They constantly graze on plants, insects, and small water-borne animals. These are hungry fish and they need to be fed lots of food—and quite often too. Silver Dollar fish should be fed 2 to 3 times per day, and about as much as they can eat in 3 to 5 minutes.

    Overfeeding Silver Dollar fish, while technically possible, is much harder to do than with many other aquarium fish. Due to the fact that these fish need to be fed very often, many people choose to get automatic feeders for them.

    The fact of the matter is that as long as you give your Silver Dollar fish lots of plant-based pellets and flakes, an algae wafer here and there, some fresh or boiled veggies, and an occasional meaty treat, they will be happy and healthy. Although they do eat a whole lot, they certainly are not picky in the least.
