I bought a 100 gal tank(I think it's the 72 1/2 x 18 1/2 x 19 3/8 one) about 2 months ago and it just finished cycling, I am using a fluval 404 and I am thinking about adding a hang on marineland penguin 200 but I am very undesided about what fish to go with. I have been looking at different types of tanks and I really like the ones with gars, cats and rays("monster fishes")...I also like the Oscars. I am not thinking about upgrading to a bigger tank for now so I would like some fishes that I could keep in a tank that size. Please I would appreciate any ideas in case mine is not possible...Thanks
