hey guys i've been checking around this forum for a few days after my dad allowed me to bring in a 100 gal tank in my room that has been sitting in the garage for a while now and will be getting 2 baby silver aro pretty soon. i never had an aro in my whole life and always wanted one. before, i had huge koifish that lived in the 100gal tank but now aro will take over!! anyways i need help considering if a 100 gal tank is too much for 2 baby aro (3-4 inches), what kind of chemicals should i put in the tank before letting the aro into the water, food to feed to make him bigger asap and not make the water dirty, i have a mini heater but i dont think its enough for the whole tank; do you think i need another one or get a bigger one, do i need air bubbles, and could i get any tankmate as well. thanks for your time.
