How big of a tank do I need for a oscar and what equipment do I need. I want this tank to be my best.
with both the above posts. for one oscar I'd go with a 75 gallon tank or larger (bigger is always better). if you go with a 75, personally I'd put on 2 Aquaclear 110 filters and a Visitherm stealth 250 watt or 300 watt heater. titanium heaters are also very nice but more expensive. the reason I suggest the visitherm stealth or titanium is because oscars get very big and could possibly break a glass heater if it got spooked and rammed into it once full grown. for the equipment I'd either order from www.bigalsonline.com or print out the pages on big als with the prices and take them to Petsmart who may price match for you.
