Silver Dollars won't eat

I have 11 dollars in my 75 gallon tank for 2 years now. These days I found that some of them aren't eating as they used to. I have tried veggies and even changed their food too but no change is seen. What should I do?

Silver Dollars love their veggies

I bought two on a whim and added them to my beautifully planted aquarium. They seemed to get along great with the other fish. In the morning it looked like the Tazmanian devil had buzzsawed through the forest. Aquatic moss seems to be the only live plant I've found they don't eat. For about a year I nursed a serious grudge, hoping they would die so I could replant (I even put them in a tank with Mississipi map turtles and gold fish for a while...). Well, they outlived all of my other fish and currently share their 55 gallon tank with a lone plecostomus, who is a recent addition. It has been about 9 years, maybe more, and I'm now very attached to them. With the exception of switching to plastic plants, they've been great. Entertaining to feed too as mine like to strike the food and splash a lot. I'd recommend them to anyone, but they do get big, so I'd be cautious putting them in with very small fish.

Shiny Dollars

I bought my first SD back in 05, and going strong. I have bought 4 more since and do great with my South American cichlids.

29 years old

I have 3 Metynnis Argenteus (Silver Dollars) The oldest was given to me in 1983! As hard as it might be to believe, she is still with us after 29 years! She is so old, her fins are wrinkled, like a typical senior. I make my own tank water, 100% Reverse Osmosis water then I ad the minerals and essential chemicals for a 175-225 TDS at 7.0 PH.

I have 7 silver dollars. They are very sweet and get along well in my 75 gallon tank with pleco, catfish, cardinal tetras, 3 large clownfish, 5 rummynose, etc. They love dry squid, romaine, zucchini and flakes. Very timid. They are about 8 inches and I've had them about 3 years. I love them. Some come right up to me and greet me. The person with the silver dollar that eats stones should immediately take it to a vet. Not funny at all. Sad.

Silver Dollars won't eat

My Silver Dollars won't eat. I've had them for 3 weeks, now 5" and looking thin and sunken at the bottom. Going to try earthworm and bloodworm tomorrow, thanks for your tips mk.

5 inch and 13 yrs old

I forgot to say my lone SD bought summer 98 refuses to eat every summertime, hope it gets its appetite back soon, the big one that died after 6yrs jumping off the aquarium used to eat earthworms, this one does not eat earthworms. SD has lived in my 30 gal bare tank for 13 yrs now, all by itself since its 3 SD companions did not live as long.

Your SD looks like a Piranha because they are in the same family. My SDs have always been very peaceful, but I have Angels in with them that are around the same size. I've never had anything smaller than them in the tank but my understanding is that they WILL eat smaller fish, especially if that fish is ill.

My silver dollars

I have 6 silver dollars that are about 3-4 inches. Last week I found my 6 inch pleco bones scattered around the tank. With all the similar stories I read, these awesome fish should be classified omnivorous

Silver Dollars Eating Rocks

I have 5 silver dollars and one of them likes to eat the rocks from the bottom of the tank. He is now so full of rocks that he is lumpy and one is actually poking through his skin and halfway out of it. Its wierd and no one that I have talked to has heard about a silver dollar doing this. It is usually common that goldfish eat rocks from the bottom of the tank.

Deadly Silver Dollars?

I just receiver 3 silver dollars as a gift. When I researched them the concenses seemed to be that they are peaceful and good in community tanks. The fish are only 2-3 inches. I added them to the tank on Sunday afternoon. Now 7 neons, 1 male fancy tailed guppy and 2 electric blue german rams are gone. Should I get rid of them?

Silver Dollar eats small fish

I have 2 Silver Dollars for almost a year in my aquarium along with some other tropical fish species which I dont know the name of (they are really small compering to SD). One day one of the small fish was dying, it was floating upside down. Then one of my Silver Dollars ate it - it pretty much split it into two halfs with few bites. I was really suprised becase so far they had eaten only my plants in the tank. Well I dont know if my Silver Dollar would eat the small fish if it was fine, but in a case the rest of small fish dies out, I wont buy a new one and I will keep SD in tank alone.
