20 gal tank

[Makavelli02]

Ok I have acquired a 20 gal tank. Kina given up on my oscars having friends. They are now in the 120 g tank and happy. Now I would lime to have some cool fish for my 20 g tank what can I do and how many can I get I. There I really liked the look of the rainbow shark at petland is it possible in the 20 g and are they aggressive

They can get up to 6 inches long, a bit too big for a 20.

have you got any other ideas for cool fish? Like community or semi-aggressive?

I am open to suggestion I am totally new to this

Just don't want the same situation I have with the oscars. They kinna kill everything.

Red tailed sharks will also get extremely aggressive and for a small tank, there arent many place for other fish to hide.
