Despite its robust nature, Silver Dollar Fish are quite timid. They thrive best in the company of their kind, ideally in groups of six or more.

To ensure their comfort, opt for a tank capacity of 75 gallons. Remember, your aquatic pals prefer dim lighting and plenty of hideaway spots – no need for fancy decorations or bright lights!

Keeping the Ideal Water Conditions

Water temperature of between 75 and 82 degrees Fahrenheit suits Silver Dollar Fish the most. Consistency is key here – especially during water changes! A moderately acidic environment is preferable. Make sure to frequently change their filter as these fish are sensitive to high nitrate levels.

Feeding Your Fish

Part of the piranha family, Silver Dollar Fish have a more vegetarian palate. They love vegetable flakes and you can pamper them with some cooked peas, squash and zucchini.

However, remember to remove any leftovers to prevent dirtying the water. Every now and then, treat them with live food such as bloodworms or brine shrimp, but be mindful not to let the poor things go hungry.


Thinking of expanding your Silver Dollar Fish gang? Move the parents-to-be to another tank. These fish are very similar to angelfish in terms of reproduction habits.

With soft, warm water, dim lighting, and fine-leaved plants, you are all set for spawning. If all goes well, the female will lay up to 2,000 eggs, which hatch within three days. Remember, you will need specific foods like freshly hatched brine shrimp for the new arrivals.

Your Silver Dollar Fish will happily cohabitate with many other friendly underwater species. They are known to befriend angels, swordtails, mollies, white tip shark cats, and pictus catfish.

With enough space, they can also share the tank with zebra danios. Remember, understanding the needs of each species is the key to a harmonious aquarium life.
