Im hoping to get a silver aro, but my mom isnt sure about lettin me get a big tank. I think i might try to build a 315 gallon aquarium. 7'L 3'W 2'D, Is that a good size for one? (and of course some other fish) Maybe one could go in a smaller aquarium? If i built one that big it would take up like 1/3 of my room lol. I thought i read that plecos can suck on to aros, maybe im wrong. Thats what i was worried about. Thanks for the replys!
