I'm on the verge of buying a new tank and the space I have in which to put it is only 44 inches wide; therefore, the widest standard tank I can use is 36 inches wide, which means I'll probably be getting a 45 gallon tank. Got it? My original plan was to stock it with African cichlids with a pair of Yellow Labs as the focal points. I also considered Oscars (love 'em), but after reading posts on this site, I now know that 45 gallons is too small for Africans or Oscars. Sigh! Now I'm thinking along these possible lines: Maybe a tank of colorful schooling fish like neons or cardinals Maybe some angels (just not as colorful as I like) I would enjoy reading your thoughts on schooling fish or other fish that would thrive in a 45 gallon tank.
