I'm not sure what you want to know, 220 gal 72x30x24 is my largest tank 1 arrow 15-18 inches , rtc, tsn, 2 gt, 2 poly sen, also have 2 90 gals, a 72bow, 40 breeder , and 2 20 gals.
@OP: I think that if you want a good home for your Aro, I would skip this person. No offense Tskstorm, 220 gallons isn't the best for a Silver Aro, and theres another silver plus other massive fish.
Moonstruck, is there a Zoo you could donate him to? I know a guy who donated his silver aro when it was 18" here in Houston, I went back to the Zoo a few months back.. That Silver is close to 3 and a half feet now.
