Hello. I am a wanna-be aquarist. The only things I have purchased so far are eight books. I am a huge reader/researcher. Unfortunately, the books are only so helpful. I have set my sights on a 65 gallon acrylic tank (with stand and canopy). The tank is 48x18x20. I want to have as many fish as is reasonable (community) and live plants. With this in mind, what would be a good filter choice? (Based on what I have read, I like the external canister filter best.) Of course, money is somewhat of an issue, but I believe in spending more if it means a better product. Also, I would appreciate any other help with regards to lighting. Right now I'm trying to figure out what fish I want so I can set up the tank with specifics in mind. I've thought about creating a spreadsheet with the different categories of fish characteristics (temp, ph, etc.) that all the books list. I was going to list the fish that I find appealing from the pictures; then cross-reference those fish to find ones that would be compatible. Does this sound like a good idea? I really want to do this right, so any help would be appreciated. Thank you.
