So I was offered a 100 gallon tank (assumingly for free or dirt cheap) and plan to set up the tank rather soon. This is more or less an opinion based question, but what South Americans do you all recommend? I love red terrors, JD, GT, Oscars, whatever. Feel free to post your favorite South American fish or options that I can keep together (I hear red terrors are super aggressive). After I get some majority suggestions I'll probably post a pole to see which fish win out :)
 
Are you after pairs, community, solo male. Just south American or Central American as you mentioned jd.

South and Central between 1-3 fish. For example I could get Maybe a male and female oscar together or a solo Flowerhorn. Just looking for suggestions on a tank setup with those new world cichlids in general I guess.
 
What are the dimensions? What you can keep changes quite a bit depending on if it's a 4' 100 gallon or a 6' 100 gallon.

You mind putting your suggestions for both? It's likely to be the 4' 100 gallon but I was just told it was 100. It's coming from a friend of a friend for free.
 
Personally I think 100 gallons is on the small side for 2 adult oscars.
It would be a nice size for a group of thorichthys or a pair of cichlasoma like portalegrensis.
You could keep a few tetras and smaller cats with the ports or a group of livebearers with the thorichthys.

If you want a single fish, go for something showy and aggressive like the flowerhorn, grammodes, tetracanthus, lyonsi, something along those lines that doesn't get much bigger than 12" for this size tank.

If you want more fish, I would look at south americans, they are easier to keep together generally. severums, Oscar, chocolate cichlids, maybe some geophagus. not all together of course.
Something like
1 severum , 1 chocolate, some tetras

Stanzz ideas are good if your not locked into having 1--2 larger fish. A large group of smaller fish would probably be more entertaining, like thoricthys.

1 Oscar 1 JD and an eel perhaps?
 
It will be interesting to see what the dimensions of the tank are. 100g isn't a standard size for most glass aquarium manufacturers. There are 2 acrylic tank manufacturers (Sea-Clear and Clear-For-Life) that make a 60 x 18 x 20. Which is a pretty sweet footprint.

Beware though, someone who isn't well versed in the hobby may call something a "100 gallon" when it isn't. Twice I have responded to craigslists ads for "100 gallon fish tank" asking for dimensions and have been given dimensions for a 55g
