Hello I have been indecisive regarding what to stock my 120G tank with. the tank is 5 foot long and 2 foot deep. I would like a single large fish, but not sure what yet, I was thinking a Flowerhorn. I have just started the first cycle so I am in no rush. Also the tank is an outdoor aquarium (under complete shade) if that is any issue. EDIT additional information: -I am seeking Tropical Fish -I live in a tropical climate, it is coming into winter now 25C-27C (Water temp) Summer is 28C (Water temp) - I will have a fluorescent bulb over the tank -I do have a heater, however I think the water temps will be okay.
