Silver dollars

yippee

Thanks for the info and link, very helpful. The angels are going in a new tank i will be getting. I definitely plan on feeding the SDs lots of vegetable matter, along with algae wafers and bloodworms and brine shrimp on occasion. I definitely do a weekly water change on all of my tanks as i believe strongly in maintaining a very healthy environment for all of my fish.

Will 6 cories, and 6 SD work well?

will different SD shoal together? Say 3 silvers, 3 spotted. or 4 silver, 2 spotted?

Yes, six and six are OK now when they're young--just remember the SD will grow and require more space. And fish that attain a largish size as adult need adequate conditions to grow in or they can face internal problems (development, immune system issues, etc) arising from what is termed "stunting" which is probably due more to the water quality than the actual space; but space enters the equation because a smaller quantity of water will deterioriate more rapidly than a larger volume. If this doesn't make sense, ask and I'll explain further. For this reason I would recommend partial water changes of 40-50% weekly.

As for your last question, I have not personally kept this species (or more correctly, these species, since there are several similar in appearance and behaviour), but here's a link to one site that says they can be housed together. Silver Dollar | Metynnis argenteus You might want to do a Google search of this fish and check other sites. As others here will tell you, one can find differing information on the internet, so it is wise to check several authorities for consistent advice. This is something I have always done whenever I have considered acquiring SA fish that are new to me. I want to know exactly what I'm acquiring before I bring them home. It can save a lot of bother over unsuitable fish.

I've heard they need a six foot tank, but i'm looking into a five foot 100 gallon tank. Will this be okay for full grown SDs?

I currently have 3 SD's in a 55 gallon tank with 5 cories, a pleco and some community fish. I got the SD's as small fish and they are doing great. They've grown to about 4 inches so far. They never go after the community fish but I keep them well fed.

Hey Yippee, Sorry I didn't see your post sooner. I had 3 or 4 silver dollars along with 3 or 4 angels and some other fish and they did quite well for a long time. The SD grew up big and the angels grew big too and even had eggs, pretty neet. I had a lot of filtration but not an over kill. I had 1- magnum 350, a UV light, and the larger whisper filter. I think that's all I had. I was not good with the water changes but they did real good even with a WC every 3 months. When I moved I gave them all to the LPS. Here is pics of my tank after I moved and repopulated it. I don't see the angels but I did have them, probably after this was taken. Well, I don't know how to upload the pics here, I'll try and upload them to my profile.

And two power heads, you can see them in the pics. I got the pics on my profile

I have 3 redhooks and a spotted SD in my 55 (also a bushynose and a few corycats). When I bought my redhooks, the guy at the LFS gave me a spotted SD that had outgrown one of his customers tanks. He said that it needed a home and would do well with the redhooks. They swim together like they were all the same type of fish. At the time the spotted one was twice as big as the redhooks. In no time the red hooks were more than twice as big as the spotted. Four years later the red hooks are now 7-8 inches long. For filtration I have a penguin 350, emperor 280, and a hot mag 250. I have very hard water and and high ph. As long as I do a minimum 40% water change a week(preferably 20% twice a week), they do very well. Anything less(while I 'm on a long vacation) their fins split and get a little ragged. A few extra water changes and they are back to normal.
