Hey ive had oscars with various personalitys for 10 years,age 14 now. So i9m not a complete noob to big fish but i was looking into gars i know they need a massive tank and all that. I was juts wondering about which species is a good one,feeding agression level, hunting skills and personaility. THe store guy at the fish store near me was under the impression they only eat fish but i found that wrong with my oscars and usually find them wrong. Dont worry about tankmates the only thing im considering with gars is another gar. I ws also wondering about mixing gar species.
