Hello, my neighbor has just passed his 2 year old fish tank down to me, a 55 gallon. It's my first tank and I know nothing about maintaining fish, except for what I've been reading in the last day or so. He passed down all sorts of equipment and things I dont really need as well. My question is about my set up, I have a BIO-wheel power filter hooked up, a heater, hood with lamps, gravel and decorations, and thats about it. Is there anything else I am missing? Will just the power filter do? This question answered and any other begginer advice would be awesome. Thanks, nice site.
