New To Having A Silver Dollar Fish

Attached Thumbnails

Minimum for this fish is 30 gallons. This fish grows huge, but usually about 6 inches average, so a ten gallon tank will hold it only for a while. It is a tropical fish, so goldfish are incompatible as these fish require warmer water, 78 degrees will suffice. It is a rather hardy fish though, and it will peacefully live with other larger robust fish that will not harass it, such as the larger blue gouramis, dwarf cichlids, larger barbs and larger tetras. To keep this fish with multiple specimens, I would recommend a tank no smaller than 55 gallons.

Welcome to fishlore!

Silver Dollars are a schooling fish and grow to about 6 inches. A 10 gal tank is much too small for him. You need at least 2 more dollars for him to feel safe and a bigger tank. They are a tropical fish and can't be housed with goldfish. As goldfish need to be in cooler water as Silvers need 78-80 as most tropical fish do. They eat flakes, plants, frozen bloodworms and brine shrimp. Mine also love veggie rounds and romaine lettuce. They are fairly easy to care for. Also prefer low lighting and are skiddish so make sure you have nothing sharp in there.

It looks as though he may have finrot.

Good morning and Welcome to Fish Lore. I agree with the above posters that he really should be homed in a larger tank. They are tropical and should not be housed with goldfish. He looks fairly large in the picture and guessing him to be 3 to 5 years old. They really need to be with several of their own kind as they do like to school and it helps them to feel much safer in their environment. A very peaceful fish. They will eat flake food, or pellets, but they love veggies like lettuce, peas. If you have live plants in the tank they will probably be eaten.

You can add other tropical fish with him but research the species that you want to add before doing so. The additional fish need to be peaceful as well.

Thanks for the tips. We have him in a 10 gallon tank in our daughter bedroom for her pet and he acts like he is doing alot better then he was when we gotten him. But we have seen when someone goes around the tank he goes and hides for awhile and when the light is on he will hide until the light is off then he will come out and swim around. So we have been keeping the light off for him since her room already gets alot of light. But when our daughter goes around the tank he wont hide...So I'm taking it that he don't like a lot of moving done around his tank.

Any chance they left behind the aquarium he was in? Maybe you could get that tank.

Glad to hear that he is showing signs of improvement. Silver Dollars can be shy and take a while to adapt to their new environment. Yes, they can be startled easily.


Just wanted to say that I enjoy all your posts

Reading celebrity gossip is my guilty pleasure... lol.
Are you guys (who post pictures) the photographers, or do you find them on other sites to post here?
Saw Sinbad today, at a tropical fish store in Chatsworth. He'll be back there on Saturday to drop off his 9ft boa that they are going to sell for him. Couldn't figure out why he looked so familiar, so I said "You look so familiar..." and he replied that it's because he's always in the store. Then someone called his name from the back of the store and he laughed and said "Or maybe you've seen me somewhere else" Ha! I felt like an idiot, but at least I wasn't gushing at him or something equally annoying; we just talked snakes & reptiles while they finished my sale & his paperwork about the snake
